Description
The Johnson Controls S350PQ-1C is a System 350 proportional plus integral temperature stage module with a dual Fahrenheit and Celsius scale and analog outputs.
Per the Johnson Controls System 350 Accessory Modules Catalog Page (Code No. LIT-1922615): S350P - Proportional Plus Integral Temperature Stage Module. The S350P is used in conjunction with the A350 Series Temperature Controls to add proportional or proportional plus integral staging capability with analog 0 to 10 VDC and 0 to 20 mA outputs.
The A350A/B data sheet lists this code as S350PQ-1C Dual Scale (F and C). Per the A350 bulletin, the S350P receives power, sensor and setpoint input from the A350 control and responds with an analog output based on the A350's setpoint and sensor information, with the offset, throttling range and minimum output selected at the S350P itself.

Johnson Controls' 2025 Product Discontinuation notice describes the S350PQ-1 as a temperature expansion module with one analog output and lists it as discontinued with no direct replacement. The notice advises that System 550 C550AQN-001 control modules include two analog outputs but do not support expansion modules; for three or more analog outputs it directs users to the C550CQN-001 control module with additional C550SQN-1 expansion modules. Check availability before specifying.
