PRODUCT INFORMATION
Product Overview
The General Electric IS220PSVOH1A is a Mark VI / Mark VIe PSVO Servo Control Module. It provides an electrical interface between I/O Ethernet networks and a TSVO servo terminal board. This pack operates within steam and gas turbine systems using Speedtronic control technology. The pack works with the WSVO driver module to regulate two servo valve position loops.
The internal processor board includes flash memory, RAM, local power supplies, and input power connectors. An onboard internal sensor provides continuous temperature monitoring. Diagnostic faceplate LEDs display status for ENet1, ENet2, Power, Attention, and ENA1/2. The unit connects to an acquisition board and features conformal coating protection. ToolboxST software enables auto-reconfiguration or manual reconfiguration when replacing hardware.
