The Festo CPX-FB37 is a fieldbus node in the CPX modular automation platform, classified as a PLC expansion module. It's the communication gateway that ties the CPX I/O island to the higher-level controller — the part that makes the valve terminals and I/O modules talk to the PLC.

Frequently asked questions
Where can I buy CPX-FB37 and how is it quoted?
Sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here.
Will CPX-FB37 drop into a panel that was specified around CPX-FB40 without rewiring?
Yes — both weigh 0.13 kg and share the same PLC expansion module category, so the physical footprint and DIN-rail fit are identical. No rewiring or bus-cable change needed.
