Product Overview

The General Electric IS220PDIAH1B is a Mark VIe I/O pack used to interface discrete field contact signals to the control system through a matched terminal board. It functions as a distributed I/O node in Speedtronic architectures, supporting reliable signal acquisition and cabinet-level integration for turbine and balance-of-plant control applications.

Designed for industrial duty, the module supports common 24 VDC control power practices and is suited for installations where robust environmental tolerance and compliance requirements are important. It is typically selected for like-for-like replacement in existing Mark VIe systems and for maintaining installed-base configuration consistency.
