Overview
IS220PSVOH1A is a servo I/O pack for GE Speedtronic Mark VIe turbine control system. It outputs high-precision drive signals to hydraulic servo valves, regulating fuel valves, inlet guide vanes and other actuators of gas turbines. This module receives position feedback signals and forms a closed-loop servo control circuit. It supports simplex, duplex and triple modular redundant (TMR) configurations. Paired with dedicated terminal boards, it provides accurate actuator positioning for turbine governing control.
Key Features
- Dual 10/100Mbps full-duplex Ethernet ports for IONet communication
- Front panel LED indicators: PWR, RUN, LINK, ATTN, WDOG for quick on-site status diagnosis
- IR local service port for module configuration, calibration and troubleshooting
- High-resolution analog output for hydraulic servo valve driving
- Accepts LVDT position feedback for closed-loop position control
- Fast response to adjust turbine actuators dynamically
- Rugged hardware designed for continuous operation in power plant control cabinets
