NI cFP-CB-1 Integrated Connector Block

The NI cFP-CB-1 Integrated Connector Block is a field-wiring interface accessory for NI Compact FieldPoint I/O modules. It terminates external sensor and actuator signals to the cFP system via 36 screw terminals, eliminating complex internal wiring and reducing installation errors. The connector block mounts directly to the cFP backplane using standard 37-pin D-Sub connections and operates across industrial temperature ranges with built-in strain relief and wire management for high-vibration environments.
