Features:
- Eight isolated 24 VDC inputs accepting PNP and NPN signals.
- Six 250 VAC relay outputs arranged across two common groups.
- CS31 remote-unit architecture with local extension capability.
ICMK14F1 1SBP260050R1001 brings field inputs, relay switching and the CS31 network interface into one AC31 remote station.
The input electronics filter transitions for at least 5 ms and isolate the field channels from the unit electronics through the specified test barrier.
Its relay section switches externally powered loads; protective devices remain part of the field circuit rather than the relay module itself.
The ABB ICMK14F1 1SBP260050R1001 Central Extensible Remote Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the field points are divided
- Input Side: Eight isolated 24 VDC channels evaluate PNP or NPN field signals.
- Transition Handling: The 5 ms minimum filter separates normal input states from short changes.
- Output Side: Six relay contacts switch externally powered loads at up to 250 VAC and 2 A.
- Common Groups: The relays are divided into one two-output group and one four-output group.
Remote-station and local-extension path
- Controller Context: The remote unit is specified for AC31 Series 50 and Series 90 basic units.
- Network Link: CS31 carries the remote I/O relationship back to the basic unit.
- Local Expansion: Central extension modules attach through the extensible-unit interface.
- Station Role: Integrated inputs and relay outputs remain available at the decentralized location.
Supply demand and field-protection boundary
- Supply Window: The unit operates from 19.2 to 30 VDC with reverse-polarity protection.
- Load Change: Typical demand rises from about 80 mA alone to 400 mA at maximum configuration.
- Module Heat: Dissipation is specified at 5 W.
- External Devices: Relay circuits require field-side short-circuit, overload and inductive-surge protection.
Cable-length and isolation limits
- Input Runs: Limits are 300 m unshielded and 500 m shielded.
- Output Runs: Limits are 150 m unshielded and 500 m shielded.
- Isolation Boundary: Input channels are tested at 1500 VAC against the electronics.
- Cabinet Wiring: Field conductors and protection must follow the documented AC31 installation rules.
