2 XTM/XPx—XTM-905 Extension Module, XPx-xxx Expansion Modules
Introduction
The XTM-905 Extension Module and XPx-xxx Expansion Modules
provide additional physical inputs and outputs for DX-9100, DX-912x
(LONWORKS® compatible), and DX-9200 (LONWORKS compatible)
controllers. The XTM module provides the processing power and
communications interface, and the XPx modules provide the analog and
binary inputs and outputs. The XTM-905 replaces the XT-9100 extension
module.
The DX controller communicates with the XTM-905 via the XT Bus. By
connecting XPx modules to each XTM-905, sets can be built with up to
eight binary inputs/outputs and up to eight analog inputs/outputs, or up to
sixteen binary inputs/outputs with eight counter functions. XPx modules
provide triac outputs or relay outputs.
The status of all binary inputs and outputs and the value of analog outputs
are indicated by Light-Emitting Diode (LED) displays built into the front
panels of the modules. On XPx output modules with the manual override
function, switches are provided to set outputs to manual mode for
maintenance or emergency override purposes, if required.
The modules are designed for installation on standard DIN rails within a
control cabinet. The outer dimensions of the modules also conform to a
DIN standard for small, wall-mounting enclosures, which allow access to
the indicator lamps and controls on the face of the module, yet protect the
user from the internal wiring.

Features Some of the features of these modules include:
• range of modules for flexible configuration of from 4 to 16 input/output
points
• analog inputs 0-10V, 0/4-20 mA, Resistance Temperature Device
(RTD) (Pt1000, Ni1000, A99, Pt100, and Ni100), or 5K ohm
potentiometer
• analog outputs 0-10V or 0/4-20 mA, with LED indicators (and the
option for manual override on the XPA-4x2 module)
• binary inputs with LED indicators
• binary triac outputs for switching 24 VAC with LED indicators and
option for manual override
• binary relay outputs (for up to 250 VAC) with LED indicators and
option for manual override
• standard screw terminals or screw terminals with quick disconnect
feature
• communications serial port (RS-485) for the XT Bus from the DX
controller
• enclosure to DIN dimensions in self-extinguishing ABS (polycarbonite
plastic material)
• DIN rail mounting
• parameter entry by personal computer and GX-9100 Graphic
Configuration software (GX Tool)
• self-checking diagnostics for correct hardware configuration
• the ability to reside on XT Bus with XT-9100 extension models
(eight extension models maximum on XT Bus)
Application The modularity of the design makes the extension modules ideal for
distributed monitoring and control in conjunction with the DX-9100,
DX-912x (LONWORKS compatible), or DX-9200 (LONWORKS compatible)
controller, and reduces wiring costs to a minimum.
However, for large, centralized plant monitoring and control, the design
enables high density installation in large control cabinets and requires no
extra terminal blocks for field wiring. The modules are also available with
disconnect terminals where required for conformance with local
termination codes for supervisory systems.
The XTM-905 configuration and operating parameters are entered using a
Personal Computer (PC), and configuration software is available from
Johnson Controls. Configuration data is downloaded via the DX controller
and is stored in EEPROM memory, which requires no battery support.
XTM/XPx—XTM-905 Extension Module, XPx-xxx Expansion Modules 5
For details of the configuration requirements for the DX controller, refer to
the DX-9100 Configuration Guide (LIT-6364030).
Note: XTM-905 modules are designed to connect to the XT Bus of a DX-
9100, DX-912x, or DX-9200 controller. For connection to the
N2 Bus, use XTM-105 modules. Refer to the XTM-105 Extension
Module, XPx-xxx Expansion Modules Technical Bulletin
(LIT-6364200).

XTM/XPx—XTM-905 Extension Module, XPx-xxx Expansion Modules 7
Note: The modules with disconnect terminals differ from the modules
with standard screw terminals only in the extra height of the body
needed to accommodate the larger disconnect terminal blocks. The
characteristics and specifications of the two types of modules are
otherwise identical. Where the technical descriptions or
diagrams in this document name or show the standard screw
terminal model codes, the discussion applies equally to the
module with disconnect terminals.
8 XTM/XPx—XTM-905 Extension Module, XPx-xxx Expansion Modules
Design Considerations
Power is supplied to the XTM-905 by a standard 24 VAC power
transformer (not supplied). Interconnecting ribbon cables supply 24 VAC
power from the XTM to all the expansion modules connected to the XTM.
Additional ribbon cables connect the XTM’s communications bus from
module to module. For environmental requirements, see Specifications
and Technical Data in this document.
XTM-905 An extension module assembled unit consists of one XTM-905 extension
Hardware module and one or two expansion module positions known as XP1 and
Configurations XP2.

Figure 5: Extension Module Configuration Positions
Each position may contain either one 8-point module or two 4-point
modules. If 4-point modules are installed in either position, then the half
positions will be referred to as XPxA and XPxB (for example, the
two 4-point module positions in XP1 are called XP1A and XP1B).
Analog modules XPA-8x1-5 are 8-point modules and modules XPA-4xx-5
are 4-point modules. All binary modules with inputs and outputs are
considered to be 8-point modules by the XTM-905. Only the binary
modules XPE-444-5, XPE-454-5, XPE-464-5, and XPE-474-5, which
have only four outputs, are considered 4-point binary modules by the
XTM-905.
XTM/XPx—XTM-905 Extension Module, XPx-xxx Expansion Modules 9
The following rules apply to the choice and placement of the various
modules connected to one XTM:
• The position XP1 may contain analog type modules or binary type
modules (but not both) and any binary inputs will have the counter
function.
• The position XP2 is optional and may contain only binary type modules
without the counter function.
• One 4-point binary module may be installed in the XP1 position
(XP1A) if there is an 8-point binary module or no module in the XP2
position, and one 4-point binary module may be installed in the XP2
position (XP2A) when the XP1 position is filled. A 4-point binary
module placed after XP1A will be configured as XP1B and not as
XP2A, and three 4-point binary modules will be configured as XP1A,
XP1B, and XP2A.
• An 8-point binary module placed after XP1A will be configured as
XP2.
• The XP1 and XP2 positions each can be filled with two 4-point binary
modules, or filled with an 8-point binary module.
Correct configurations can be built up from the currently available
modules using Table 2:

Input Expansion modules with analog inputs accept 0-10V, 0-20 mA, or passive
Characteristics RTD sensors by jumper configuration (XPA-8x1) or software
configuration (XPA-4x1). For 0-20 mA DC inputs, a zero offset of 4 mA
may be set by software configuration. The measurement unit of each RTD
input can be configured for degrees Celsius or degrees Fahrenheit.
Voltage and current inputs, and 5K ohm potentiometer inputs of the
XPA-4x1 module can be ranged using the programmable range parameters
as follows:
• lower end of range (LR) for 0V/0 mA/4 mA/0 ohm
• higher end of range (HR) for 10V/20 mA/5K ohms
The analog input value is calculated as follows:
% PR
AI = ∗ (HR − LR ) + LR
100
where %PR = the analog value in percent of the physical range (0-10V,
0-20 mA, 4-20 mA, 0-5K ohms).
XTM/XPx—XTM-905 Extension Module, XPx-xxx Expansion Modules 13
Notes: For a potentiometer input, the value of %PR is always related to a
maximum resistance of 5K ohms. For potentiometers with another
resistance value, the maximum value of %PR is as follows:
100
Maximum %PR = r∗
5
where r is the potentiometer resistance in K ohms.
The value of HR must correspond with a %PR value of 100 or an
equivalent input of 5K ohms. For example, for a 2K ohm
potentiometer representing a physical quantity of 0-250 units, the
value of HR must be set to:
5
250∗ = 625
2
Voltage and current inputs from a differential pressure sensor, for
example, can be linearized by a square root function which
operates over the complete range of the input according to the
following equation:
% PR
AI = ∗ ( HR − LR) + LR
100
where %PR = the analog value in percent of the physical range
(0-10V, 0-20 mA, 4-20 mA).
For all analog input types, a configurable filter is incorporated for the
reduction of signal instability. The filter function is:
1
FVt = FVt −1 +
1 + Ts
( AI t − FVt −1 )
where: FVt = Filtered Analog Value at current time
FVt-1 = Filtered Analog Value at previous poll
AIt = Actual Analog Value at current time
Ts = Filter Time Constant (seconds)
A Ts value of 0 disables the filter.
14 XTM/XPx—XTM-905 Extension Module, XPx-xxx Expansion Modules
Expansion modules with analog inputs will accept Ni1000, Pt1000, A99,
and, on the XPA-4x1 only, Pt100 and Ni100 passive RTD sensors. The
measurement ranges for these sensors are fixed, as shown in the table
below:

Ni 1000 (Landis & Gyr) Sensor -50 to +160°C (-58 to +320°F)
An offset parameter (OFS) is available, which is added to the analog input
value to compensate for wiring resistance.
Expansion modules with analog inputs provide a 15 VDC supply for
analog input sensors. The maximum current supplied from this power
supply must not exceed 30 mA for the XPA-8x1 and 20 mA for the
XPA-4x1.
A high and low alarm limit setting with alarm limit differential can be
assigned to each analog input.

Output Expansion modules with analog outputs provide 0-10 VDC, 0-20 mA or
Characteristics 4-20 mA outputs by software configuration. The type of output (voltage or
current) is selected on the XPA-8x1 by a jumper, and on the XPA-4x2 by
the output terminals used.
The output signal is proportional to the requested analog output value from
0 to 100%.
Manual Override The XPA-4x2 Analog Output module with manual override has
Operation of the four pushbutton switches on the right of its front panel and a vertical
Analog Outputs column of eleven LEDs on the left. The LEDs display either the current
(XPA-442 and status of all four outputs or the current value of a selected output. The
XPA-452 Only) buttons are used to change the display mode and to manually override the
output value of the currently selected output.

The functions of the four pushbutton switches are as follows:
• Use the top button labeled Ù to toggle the display mode between status
display for all four outputs and actual value display of the selected
output.
• Use the button labeled A/M to toggle the selected output between
Automatic (DX-91x0) and Manual (local) operation. The button is
active only in the status display mode and for the selected output.
• Use the two buttons labeled × and Ø, depending on the display mode,
either to select an output or to change the value of the currently selected
output when it is in Manual mode. When selecting an output, either
button, when repeatedly pressed or held down, cycles in the indicated
direction through the four outputs (AO1 to AO4).
In the status display mode, two LEDs for each output are used. The upper
LED of the pair flashes when the output is selected. Otherwise, it is off.
The lower LED of the pair is constantly lit when the output is in Manual
mode, and is off when the output is in Automatic mode. Only one output
may be selected at one time, but any number of outputs, or none, may be in
Manual mode.

Figure 8: Output Status Display
By pressing the Ù button, you can change the display mode to show the
actual value of the selected output, which uses all 11 LEDs. The lowest
LED represents an output of 0%, and a full column of 11 lit LEDs
represents 100%. Each LED in the column represents a 10% step in the
value of the output.
Note: When setting the value of an output in Manual mode, each press of
the × or Ø button changes the value by 5%. Therefore, you may
have to press a button twice to see a change in the displayed value.
If no button is pressed within a period of one minute, the display
automatically returns to a quiescent state where only the lowest LED is on.
Pressing any button will restore the display to operational mode.
Binary Input The two 8-point binary input expansion modules currently available are

(normally open), or when disconnected from the common by the opening
of an external, normally-closed contact. The red LED is lit when the
corresponding input is active. Eight LEDs indicate the status of each input
on the binary expansion module.

A binary input may be defined as maintained or pulse type by software
configuration. With maintained type contacts, the status reported by the
XTM follows the status of the contact. With pulse type contacts, the XTM
sets and resets the status at each pulse of the input contact. This type is
recommended only for manual override functions, such as in lighting
control, where the user gets confirmation of the override request by a
verifiable response.
Counter The counter function is provided for the binary expansion module if
Function installed in position XP1. The number of input contact transitions required
to increment the counter can be set in the XTM module. The counter
values are stored in 4-byte memory locations in Random Access Memory
(RAM, Items CNT1-CNT8), and, on power failure, the values are
automatically saved in EEPROM and then restored to RAM when power
returns. The pulse frequency at the input should not exceed 25 Hz and the
pulses must have a minimum On time of 20 ms, and a minimum Off time
of 20 ms.
For consistency with the DX controller display, the counters will roll over
at the decimal value of 9,999,999.

Input Binary inputs are powered by the XTM module. By software
Characteristics configuration, the input is active (set) when connected to the binary input
common via an external potential-free contact (normally open), or when
disconnected from the common via an external potential-free contact
(normally closed). The green LED is lit when the corresponding input is
active (set). Normally open contacts are recommended for all status
feedback indicators.
Binary inputs may be defined as maintained or pulse type by configuration.
With maintained type contacts, the binary input status follows the status of
the contact, and this type is recommended for all status feedback indicators
and alarm signals.
With pulse type contacts, the binary input status is set and reset at each
pulse of the input contact.
Counter The counter function is available for the four inputs of a binary expansion
Function module in position XP1. The number of input contact transitions required
to increment the counter on each input can be set in the XTM module. The
counter values are stored in 4-byte memory locations in RAM (Items
CNT1-CNT4), and, on power failure, the values are automatically saved in
EEPROM and then restored to RAM when power returns. The pulse
frequency at the input should not exceed 25 Hz, and the pulses must have
a minimum On time of 20 ms, and a minimum Off time of 20 ms. The
counters will roll over at the decimal value of 9,999,999.
Binary Output The binary outputs associated with binary output modules XPM/L/E-4x1
Characteristics do not have to be configured, as the module always drives the output
(XPM/L/E-4x1) relays as momentary (XPM), magnetically latched (XPL), or electrically
latched (XPE), according to the type of module. The only exceptions are
the XPE-4x4 modules (see Relays [XPE-4x4 Modules] and Triac Outputs
[XPT-4x1 and XPT-8x1] later in this chapter).
Momentary Two contacts are provided for each binary output, one for the On
Relays (XPM) command (1) and one for the Off command (0), and will change over
momentarily upon request. The contacts are interlocked such that only
one output can be active at one time, and the length of the active pulse is
determined by configuration (default is 20 ms). Activating the off
command removes power from the holding circuit output terminal.
Magnetically The change-over contacts for the binary output change state on command
Latched Relays and remain in the commanded state (0 or 1) by a magnetic latch on the
(XPL) relay. The magnetically latched contacts do not change state on 24 VAC
power loss.

Relays (XPE-4x4 The binary outputs of XPE-4x4, XPT-4x1, and XPT-8x1 modules are

Triac Outputs contacts with a single supply terminal for all four outputs. Triac outputs
(XPT-4x1 and are electrically separated. The contacts or triac of an output configured as
XPT-8x1) an on/off binary output will close or open on command and will remain in
the commanded state. If the module loses 24 VAC power, the triac will
open, and the relay will go to the Off state.
The contacts or triac of an output configured as a pulse binary output will
change state momentarily on each command (on or off). The length of the
pulse is determined by configuration (default is 20 ms).
Manual Override The binary output modules with manual override have three to
Operation of the four switches (depending on the number and type of outputs) on the right
Binary Output side of their front panels. The switches on the XPL/E modules have
Modules three positions and latch in each position (up, middle, down). The switches
on the XPM modules have two or three positions (up, middle, down).
However, since the outputs are momentary, some of the switches do not
latch but are instead spring loaded to return to the middle position after
they have been pushed either up or down.
By software configuration, the manual override operation may be disabled
when the module is connected to an active DX controller. In this case, the
manual override operation is enabled only when XT Bus communication
fails and the module is in a Standalone mode.
The LEDs on the left side of the front panel show the last commanded
state from the DX controller.

Each binary output on an XPL/E/T module has one switch with positions
labeled A, 0, and 1. The A position sets the output to Automatic mode,
which means the output is controlled by the DX controller. Setting the
switch to either 0 or 1 sets the output both to Manual mode and to the
selected output state.

Each binary output on an XPM module has two switches, where the first
switch has positions labeled A and M, and latches in each position. The
second switch has Positions 0 and 1, and is spring loaded to return to the
middle position after having been pushed either up or down. The
A position on the first switch sets the output to Automatic mode for
control by the DX controller. The M position sets the output to Manual
mode. Once in Manual mode, the second switch can be used to pulse the
output to either State 0 or 1.

Installation
The XTM-905 must be supplied with a 24 VAC power source. All models
are suitable for 50 Hz or 60 Hz through software configuration. The
extension modules are then supplied with 24 VAC power from the XTM
via the expansion module supply bus, which is connected with the ribbon
cables provided.
Two modules (XTM-905 and XPA-8x1) require that hardware settings
(jumpers and DIP switches) be made before power is supplied to the
modules. See Commissioning and Troubleshooting in this document for
instructions.
! CAUTION: Shock hazard. Connections to the terminals of XPM,
XPL, and XPE expansion modules may carry up to
250 VAC. Isolate before servicing.
General While every reasonable precaution has been taken to prevent electrical
Guidelines disturbances from adversely affecting the operation of the modules, lack of
attention to generally accepted control wiring installation practices can
lead to module problems in high electromagnetic field environments. In
general, follow the guidelines below:
• Do not mount the modules in heavy-duty switch gear cabinets or in
cabinets with frequency converting or phase-cutting equipment.
• Low voltage wiring in electrical cabinets must be physically separated
from line voltage and power wiring, and a distinctive color (e.g., white
or pink) for each type of wiring is recommended.
XTM/XPx—XTM-905 Extension Module, XPx-xxx Expansion Modules 23
• To avoid electrical interference in field cables:
- Keep input and output point cable runs as short as possible
(< 50m [165 feet]).
- Use twisted pair cables.
- Run low voltage cables separately from line voltage/power cables
(minimum 30 cm [12 inch] separation from 230V, 30A circuits).
- Do not run low voltage cables parallel to power cables for long
distances (> 3m [10 feet]).
- Do not run cables close to transformers or high frequency generating
equipment.
- Use shielded cable in high electromagnetic field environments.
Ground the shield at one end, preferably at the cabinet housing the
modules.
• For the communications bus (XT Bus), use a cable recommended for
RS-485 transmission. The cable must be shielded and the shield
grounded at one end only.
• Do not connect switched inductive loads to the 24 VAC transformer
which supplies the modules, and cable each connected load from the
transformer separately, as shown in the figure below:

Mounting and Figure 12 shows the dimensions of the XTM-905 module. All other
Wiring modules have the same dimensions except for those with disconnect
Instructions terminals, which have the height indicated by dotted lines in this figure.
When mounted on a DIN rail, the modules of an XTM device set must be
placed side by side so that the overall width of the unit is the sum of the
widths of the individual modules.

Mounting Snap the module onto the 35 mm DIN rail. To release the module, insert a
screwdriver at the base of the module (Point A), pull down to release the
retaining clip, and tilt the bottom of the module forward and up. Since the
retaining clip is spring loaded, you can also remove the module without a
screwdriver by carefully pushing the module up against the clip and then
tilting the top forward to release the top lug from the DIN rail.
