Overview

IS220PSVOH1B is a servo I/O pack in GE Speedtronic Mark VIe turbine control system. It outputs high-precision drive signals to hydraulic servo valves, governing fuel valves, steam valves and inlet guide vane actuators of gas and steam turbines. This module receives LVDT position feedback signals and builds closed-loop servo control. It supports simplex, duplex and triple modular redundant (TMR) configurations. When paired with matched terminal boards, it delivers accurate actuator positioning for turbine governing and combustion control.

Key Features

• Dual 10/100Mbps full-duplex Ethernet ports for IONet communication
• Front panel LED indicators: PWR, RUN, LINK, ATTN, WDOG for fast on-site status inspection
• IR local service port for module calibration, configuration and troubleshooting
• High-resolution analog output for hydraulic servo valve excitation
• Supports LVDT position feedback for closed-loop actuator positioning
• Fast response to dynamically adjust turbine control actuators
• Industrial rugged design for continuous operation in power plant control cabinets
