GE IS220PSVOH1B Mark VIe Servo Control Module

Product Overview

The GE IS220PSVOH1B is a Servo Control (PSVO) I/O Pack designed for the Mark VIe turbine control system. It provides an electrical interface between the I/O Ethernet networks and compatible servo terminal boards. Working with an adjacent WSVO servo driver, it controls two independent servo valve position loops, processes LVDT feedback signals, and supports turbine speed monitoring.

Technical Specifications

Key Features

• Controls two independent servo valve position loops.

• Supports up to eight LVDT feedback inputs.

• Provides two pulse-rate speed inputs.

• Generates LVDT excitation signals.

• Supports redundant I/O Ethernet communication.

• Integrated diagnostics and LED status indicators.

• Designed for GE Mark VIe turbine control systems.

Applications

• Gas and steam turbine control.

• Fuel valve position regulation.

• Steam control valve positioning.

• Electro-hydraulic servo systems.
