Product Overview

The IS220PAICH1B is an analog input and output I/O pack developed by General Electric for Mark VI and EX2100 control platforms. Designed as a field interface module, it enables accurate acquisition of analog signals from sensors while delivering controlled analog outputs to actuators and other field devices. The module connects to dedicated terminal boards and communicates directly with the Mark control architecture, supporting stable and deterministic signal processing in critical automation systems.

This B-revision I/O pack operates from a standard 24 VDC or 28 VDC supply and incorporates enhanced internal monitoring to ensure reliable operation. Its compact design allows installation close to field wiring, reducing signal degradation and improving system maintainability in both hazardous and non-hazardous environments.
