Description

The ABB ICMK 14 F1, product ID 1SBP260050R1001, is an extensible remote unit engineered for the Advant Controller 31 (AC 31) automation system. It serves as a decentralized connection point on the CS 31 master/slave bus, enabling localized distributed applications close to sensors and actuators. The unit features 8 built-in isolated binary inputs and 6 relay outputs. Designed for modular flexibility, it supports the local addition of up to 6 binary or analog extension units to expand system I/O capabilities up to a maximum of 8 analog input channels and 8 analog output channels.

Features

Decoupled architecture supporting up to 6 local binary or analog extension units.
Integrated CS 31 multipoint serial interface for high-speed fieldbus communication.
Configurable input processing accommodating both PNP and NPN sensor types.
Electrical isolation between inputs and internal electronics up to 1500 V a.c..
Direct diagnostics via localized status visualization LED indicators (POWER, RUN, ERR) on the front panel.
Built-in rotary selector switches on the front panel for manual decade and unit addressing on the bus.

Applications

Distributed machine control networks.
Industrial manufacturing processes (e.g., ceramic, floor board, and electrical contactor assembly lines).
Water treatment plant automation.
Infrastructure management including building power and tunnel ventilation systems.

Installation Guidelines

Mounting: Secure the unit to a standard 35 mm DIN rail using the integrated mounting lock, or use 4 mm diameter (M4) screws for panel mounting.
Wiring: Utilize removable terminal blocks supporting a maximum wire cross-section of 2.5 mm². Tighten connection screws to an indicative torque of 0.5 Nm.
Earthing: Ensure robust earthing by connecting the rigid or multi-conductor AWG 14 wire to the unit's grounding plate fixture.
Bus Termination: Connect a 120 Ohm, 0.25 Watt line termination resistor across each extremity of the RS 485 CS 31 bus network.
