IS220PSVOH1A Servo Control Pack
The IS220PSVOH1A is crucial in General Electric’s Mark VI or Mark VIe systems for controlling steam and gas turbines.
The electrical interface connects a TSVO servo terminal board to one or two I/O Ethernet networks.
The IS220PSVOH1A’s primary function is to manage two valve position loops using the WSVO servo driver module.
This allows for precise control over the turbine systems, ensuring optimal performance and efficiency.
The IS220PSVOH1A provides the electrical interface between one or two I/O Ethernet networks and a TSVO servo terminal board.
The IS220PSVOH1A uses the WSVO servo driver module to handle two servo valve position loops. The PSVO has:
