GE IS220PSVOH1B

Product Overview

The GE IS220PSVOH1B is a servo control I/O pack designed for the Mark VIe turbine control system. It provides an electrical interface between the I/O Ethernet network and a compatible servo terminal board. Working with the associated servo driver, it supports precise control of hydraulic servo valves used in turbine systems.

The module plays an important role in actuator positioning. It processes position feedback and control signals to help regulate turbine valves and maintain stable equipment operation.
