System 350™
S350A Temperature, S351A Humidity,
and S352A Pressure Stage Modules
The S350A, S351A, and S352A Stage Modules are
intended to be used with System 350™ controls. Each
of these stage modules plugs into the respective
control module to add multiple-stage capability. These
stage modules have Single-Pole, Double-Throw
(SPDT) relay output with Light-Emitting Diode (LED)
indication.
As are all System 350 products, the stage modules are
housed in NEMA 1, high-impact thermoplastic
enclosures. The modular design provides easy,
plug-together connections for quick installation and
future expandability.
Figure 1: System 350 Stage Module
Features and Benefits
Modular Design Permits system to be configured to
equipment, with convenient, future expansion
made easy
Plug-together Connectors Eliminates wiring between modules and
and 35 mm DIN Rail reduces installation costs
Mounting
Selectable Mode of Provides independent relay energization,
Operation either above or below setpoint, for
cooling/heating (S350A),
dehumidification/humidification (S351A), or
direct acting/reverse acting (S352A)
Adjustable Differential Enables user to match the range of
temperature, humidity, or pressure stage
modules to specific application requirements
Adjustable Offset Allows multiple stage sequencing of 1-30F°
(0.5-17C°) (S350A), 2-30% RH (S351A), or
2-50 psi (S352AA-2)

The S350A, S351A, and S352A Stage Modules
provide SPDT relay output. A front panel LED lights to Operation Mode Selection
indicate when the relay is energized. The S350A, S351A, and S352A utilize jumpers (at
jumper terminal J2) to select the operation mode. (See
