FX-PCA Series Controllers are programmable controllers that can communicate using BACnet®/IP, MS/TP, or N2 communications protocols, depending on the model. The FX-PCA4911 communicates using BACnet/IP communications protocol, and is a BACnet Advanced Application Controller (B-AAC). The other FX-PCA Series controllers can be switched between MS/TP and N2 Communications protocols and when used as MS/TP devices are BACnet Advanced Application Controllers (B-AACs).
FX-PCA Series Controllers can also operate as stand-alone controllers in applications that do not require a networked supervisory device or for network applications where it is preferred to have the scheduling, alarming, and/or trending performed locally in the field controllers.
The FX-PCA4911 communicates using BACnet/IP communications protocol, and is a BACnet Advanced Application Controller (B-AAC). The FX-PCA4911 controllers operate on BACnet/IP networks and integrate into Johnson Controls and third-party systems. The FX-PCA3613 controller runs pre-engineered and user-programmed applications and provide the inputs and outputs required to monitor and control a wide variety of HVAC and other facility equipment. PCA36 controllers operate on an RS-485 BACnet® MS/TP Bus and integrate into Johnson Controls® and third-party BACnet systems. PCA36 controllers include an integral real-time clock, which enables the controllers to monitor and control schedules, calendars, and trends, and operate for extended periods of time as stand-alone controllers when offline from the system network.
FX-PCA2612 controller models feature line-voltage relay outputs, making these controllers well suited for use in terminal units. The FX-PCA2612-2 model uses a line-voltage power supply, eliminating the need for a 24 VAC transformer in line-voltage applications.
