IS200TGENH1A - TGEN Generator Monitor Terminal Board | GE Mark VI | B7B

The General Electric IS200TGENH1A (TGEN) is a Generator Monitor terminal board for GE SPEEDTRONIC™ Mark VI turbine control systems, providing 4 analog current inputs (4-20 mA), 2 potential transformer inputs, and 3 current transformer inputs used to monitor generator three-phase voltage and current and calculate three-phase power and power factor.

TGEN works with the IS200VGEN processor board and supports both simplex and TMR applications; one TGEN connects to a VGEN board with a single cable, and in TMR systems TGEN connects to three VGEN boards using three separate cables. For large steam turbine applications, the VGEN/TGEN pair also supports power load unbalance (PLU) and early valve actuation (EVA) functions using fast-acting solenoids on an associated TRLY terminal board.

For maintenance and procurement teams, IS200TGENH1A should be matched to the existing VGEN board and redundancy configuration per GEH-6421 Volume II before ordering a replacement.
