IS200VSVOH1BEF VME Servo Control Board
The General Electric IS200VSVOH1BEF is a GE Mark VI VME servo control board designed for precise electro-hydraulic valve regulation. It combines servo-current control, LVDT excitation and valve-position feedback processing for gas- and steam-turbine applications.
Four bidirectional servo-output channels for fuel or steam valve actuation.
LVDT excitation and feedback processing support closed-loop valve positioning.
Designed for the GE Speedtronic Mark VI VME platform and TSVO/DSVO interfaces.
Power generation, oil and gas, petrochemical plants and turbine maintenance.

FAQ
1. What is IS200VSVOH1BEF used for?
It is a Mark VI VME servo board used to regulate electro-hydraulic valves through position feedback and servo-current outputs.
2. Does it process valve position?
It processes LVDT feedback associated with valve position. Correct wiring, board pairing and controller configuration remain essential.
3. Can another IS200VSVOH1B suffix replace it?
Not solely because the base number matches. Verify the full revision, interfaces and site requirements before substitution.
4. What should be checked before installation?
Verify the nameplate, revision, connectors, rack and terminal-board compatibility; use ESD protection and back up the configuration.
5. What do the LEDs indicate?
RUN, FAIL and STATUS provide a quick state reference; use Mark VI diagnostics and maintenance procedures for final troubleshooting.
6. Where is the board typically applied?
In Mark VI-controlled gas or steam turbines across power, oil and gas, petrochemical and cogeneration operations.
