System 350 Display Modules
The D350, D351, and D352 Display Modules are
TM
designed for use with System 350 temperature,
humidity, and pressure controls to provide a digital
readout of sensor or setpoint values—at the push of a
button.
As are all System 350 products, the display modules
are housed in a NEMA 1 high-impact thermoplastic
enclosure. The modular design provides easy,
plug-together connections for quick installation and
future expandability.

The display modules are housed in a compact NEMA 1
plastic enclosure designed for standard 35 mm DIN rail
mounting. The modules are not position sensitive, but
they should be mounted for convenient wiring and
adjustment. Four key-slot mounting holes on the back
of the control case are provided for surface mounting
Figure 2: Display Module Features when required.
The display modules plug into the control and other
System 350 add-on modules via 5-pin connectors
located on either side of each module.
O peration System 350 modules can be arranged in any order;
The display modules receive their power, sensor, and external wiring is not required to interconnect
setpoint information from a System 350 control components. (For optimal system accuracy, mount the
module. A 3-digit LCD (Liquid Crystal Display) provides D350 series modules at the far right end of the

power is applied.
To view the setpoint reading, press the PRESS FOR

IMPORTANT: The D350, D351, and D352 Display
Modules are matched to the A350,
W351, and P352 controls,
respectively. If an incorrect display
module is used on a system, the
display provides inaccurate readings.
