Features:
- Receives generator and bus potential signals through the TGEN terminal interface.
- Combines voltage, current, and configurable analog measurement channels.
- Transfers twelve relay-output commands to a connected TRLY board.
IS200VGENH1B calculates three-phase power, power factor, and frequency from its generator-monitor input set.
Two three-phase potential-transformer groups and three single-phase current-transformer channels feed IS200VGENH1B through TGEN.
IS200VGENH1B adds four analog channels that can accept 4–20 mA, ±5 VDC, or ±10 VDC signals.
The General Electric IS200VGENH1B Generator Monitor Board may be available for purchase and support from Apter Power for installed Mark VI systems.

Terminal-Board Connection
- Field interface: TGEN terminates the generator-monitor voltage and current signals.
- Simplex path: One VGEN connection carries the TGEN signal set.
- TMR path: Three VGEN connections distribute the signals across redundant processors.
- Board pairing: IS200VGENH1B processes the TGEN terminal-board inputs.
Voltage, Current, and Analog Channels
- Potential inputs: Two three-phase PT groups represent generator and bus voltages.
- Current inputs: Three single-phase CT channels carry generator current measurements.
- Analog inputs: Four channels accept 4–20 mA, ±5 VDC, or ±10 VDC.
- Channel purpose: The combined inputs supply the generator-monitor calculations.
Computed Electrical Quantities
- Three-phase power: IS200VGENH1B derives power from the PT and CT input set.
- Power factor: The board evaluates the phase relationship between voltage and current.
- Frequency: Generator frequency is calculated from the incoming voltage signals.
- Protection functions: PLU and EVA processing is available for large steam-turbine configurations.
Command Transfer to TRLY
- Output count: Twelve relay commands originate from the IS200VGENH1B processing path.
- Terminal destination: The command set is delivered to a TRLY relay terminal board.
- Functional separation: Generator measurements remain on VGEN while field relay wiring terminates on TRLY.
- System path: The relay interface links calculated conditions to external control circuits.
