GE IS220PDOAH1A Steam Turbine Control System Module

Product Description

GE IS220PDOAH1A is a Discrete Output Pack for the GE Speedtronic Mark VIe turbine control system, a distributed I/O unit. Equipped with an embedded processor and dual redundant Ethernet ports, it transfers control signals between the main controller and discrete output terminal boards. It can drive up to 12 relay outputs and collect feedback signals from terminal boards. It is compatible with both electromagnetic relay and solid-state relay terminal boards. It is fitted with status LED indicators and an infrared local diagnostic port. Featuring redundant communication, fast response and excellent noise immunity, it serves as a critical spare part for interlocks, valves and auxiliary equipment control of gas and steam turbine generator sets.
