Description
. . . . . The Johnson Controls PCX2723-0 is an expansion input/output module from the Facility Explorer FX-PC Series. Expansion modules of this kind increase the number of field points connected to an FX-PCA, FX-PCG or FX-PCV programmable controller, or to a supervisory controller, without replacing the controller itself.
PCX modules operate on an RS-485 field bus as BACnet Application Specific Controllers (B-ASCs), so the additional inputs and outputs appear to the control system as network points. The existing control logic and field wiring stay in place, and the extra capacity is added on the bus - the standard remedy for a controller that has run out of points.
Please note: the exact input and output count for this particular variant is not stated in the documentation available to us. Within the same PCX27xx family the PCX2721 provides eight universal inputs and two analog outputs, but we would rather not carry that figure across to a different suffix, since the point count is the whole basis on which one of these modules is selected. Please confirm the configuration before ordering.
