General Electric IS200VGENH1B Generator Monitor And Trip Board PCB Circuit Board

Product Overview

The GE IS200VGENH1B is a VME Generator Monitor and Trip Board designed for the Mark VI Speedtronic turbine control system. It interfaces with three-phase potential transformers (PTs) and current transformers (CTs) to monitor generator voltage, current, power, and power factor. The board provides specialized control functions for reheat steam turbines, including power-load unbalance protection and early-valve actuation logic. Built with a Xilinx XCS30 FPGA and XC95216 PLD, it delivers high-performance signal processing for critical generator protection applications.

FAQ

• Q: Is the IS200VGENH1B compatible with TRLY boards?
  A: Yes, it is compatible with TRLYH1B modules, but not with TRLYS1B modules.
• Q: Can it be used in TMR applications?
  A: Yes, the IS200VGENH1B supports both simplex and Triple Modular Redundant (TMR) configurations.
• Q: What generator parameters does it monitor?
  A: It monitors three-phase voltage, current, three-phase power, and power factor for comprehensive generator protection.
• Q: What is the difference between VGEN and TGEN boards?
  A: VGEN focuses on generator electrical monitoring; TGEN handles turbine-specific control functions. They often work in tandem.

Selection Tips

• Specify IS200VGENH1B for Mark VI generator protection and monitoring applications.
• Verify compatibility with existing TRLY relay boards before ordering.
• For reheat steam turbines, ensure early-valve actuation logic is enabled in the control configuration.
