The Festo CPX-FB14 is a modular electrical terminal slice for the CPX system, sitting in the PLC Expansion Modules category. It's the fieldbus node that handles the I/O communication between the CPX manifold and the controller — no relay or valve driver inside this one, just the communication interface.
Panel integration
Snaps onto the standard DIN rail inside a control cabinet. The CPX system is modular — you build the manifold stack with the FB14 as the bus head, then add I/O slices and valve terminals downstream. No special tools; just clip it on, wire the fieldbus connector, and address it via the rotary switches on the front face.
