PCX Expansion Input/Output Module The PCXs are expansion I/O modules with integral RS-485 MS/TP communications. Note: At Controller Configuration Tool (CCT) 13.0 or later, using 10.1 Release Mode, the PCGs, PCAs, and PCVs can communicate by using either the BACnet or the N2 field bus networking protocol. The operation of the PCX is not affected by the selection of the BACnet or the N2 protocol in the host controller. 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 PCA controllers, the PCXs expand the I/O interfaces of the controllers. When installed on the Field Controller (FC) Bus, PCXs can be used as I/O point multiplexors to support monitoring and control from a supervisory controller. The point multiplexor can also be useful for sharing points between other PC controllers on the FC Bus using peer-to-peer connectivity. A full range of PCA models combined with the 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. Features and benefits Standard Protocol with BTL Listing Provides interoperability with Johnson Controls and third-party Building Automation System (BAS) products that use the widely accepted BACnet ® standard. Standard Hardware and Software Platform Uses a common hardware design throughout the family line to support standardized wiring practices and installation workflows. Also uses a common software design to support use of a single tool for control applications, commissioning, and troubleshooting to minimize technical training. Universal Inputs and Configurable Outputs Allow multiple signal options per channel to provide input/output flexibility.. Complete Product Family with Modular Components Meets any HVAC equipment or building system control requirement using only the needed components. Ability to reside on the FC Bus or SA Bus Provides application flexibility PCX Series point type counts per model PCX Input/Output Expansion Modules Catalog Page LIT-1900671 2020-11-23Next >
