Product Description
GE IS220PSVOH1A Mark VIe PSVO Servo Control Module
Servo Valve Position Control Module for GE Speedtronic Mark VIe Gas & Steam Turbine Control Systems
1. Product Overview
The GE IS220PSVOH1A is a PSVO (Position Servo Valve Output) Servo Control Module designed for GE Speedtronic Mark VIe and Mark VIeS turbine control systems, used in gas and steam turbine applications. It provides an electrical interface between I/O Ethernet networks and the TSVO servo terminal board, utilizing the WSVO servo driver module to manage two independent servo valve position loops. With 8 LVDT inputs, 2 pulse rate inputs, dual Ethernet ports, and real‑time diagnostics, it enables precise servo valve positioning, actuator stroking, and performance testing, ensuring reliable turbine control in power generation, oil & gas, and industrial energy systems.
