S350A Temperature, S351A Humidity, and S352A Pressure Stage Modules Product/Technical Bulletin
A
pplication
The S350A, S351A, and S352A Stage Modules
receive power, setpoint, and sensor input from the
respective System 350 control modules. When
connected, the individual modules act as a multistage
control system.
The maximum number of stages that can be used in a
system varies with the control module type
(temperature, humidity, or pressure) and stage module
design.
Refer to Table 1 or Table 2 to determine the maximum
number of stages that may be used with each control
module. When mixing stage module designs, always
use the lower number.
Note: When using an external transformer, the
Y65 Series or other 40 VA Class 2
transformers are recommended.
