Johnson Controls S352 Pressure Stage Module

Pressure Stage Module

The S352 Stage Module is used in conjunction with the P352 On/Off Pressure Control to add multi-stage capability. Using a Y350R, up to five S352s can be added to the P352 via the 5-pin plug-together connector. Using a 40 VA or greater external transformer, up to nine S352s can be added. The S352 has a SPDT output relay and three adjustments including offset (stage setpoint), differential and mode (reverse or direct acting).



• reverse or direct acting mode, field selectable
• adjustable differential and offset
• 5-pin connector for easy installation
