Product Description
Overview
GE IS220PDIAH1B (also referenced as IS230SNCIH2A) is a Discrete Input Module (PDIA) for the GE Mark VIe turbine control system. It provides a reliable interface between field devices—such as limit switches, pushbuttons, and contact closures—and the control system. The module converts external discrete signals into logic inputs for the controller, ensuring accurate and safe input monitoring. Designed for gas and steam turbines, it offers electrical isolation, fast response, and diagnostic capabilities for mission-critical industrial environments including power generation, oil & gas, marine propulsion, and heavy industry.
