Johnson Controls P352AB Electronic On/Off Pressure Control

Electronic On/Off Pressure Control

The P352AB Electronic On/Off Pressure Control features SPDT relay output and LED indication. This control is used in conjunction with a pressure transducer and wiring harness. The pressure range is 0 to 600 psig with adjustable differential and offset ranges. The P352AB control can be used as a standalone device or in conjunction with accessory modules to control a wide variety of single and multi-stage HVAC and refrigeration applications. The Y350 Power Module, S352 Stage Module, and D352 Display Module can be used with the P352AB.



• field selectable reverse/direct acting mode
• adjustable setpoint, differential, and offset capabilities
• wall or DIN rail mounting
• stage (S352), display (D352), and power (Y350R) modules plug-together via 5-pin connectors
