CH-PCXs can serve in one of two capacities, depending on where they are installed in the control system. When installed on the Sensor Actuator (SA) Bus of CH-PCA and CH-PCX controllers, the CH-PCXs expand the I/O interfaces of the controllers. When installed on the Field Controller (FC) Bus, CH-PCXs can be used as I/O point multiplexors to support monitoring and control from a BCPro™ Workstation.

A full range of CH-PCA models combined with the CH-PCX models can be applied to a wide variety of building applications ranging from simple fan coil or heat pump control to advanced central plant management
