GE IS200TREGH2B IS200TREGH2BDC Mark VI Gas Turbine Emergency Trip Board

The GE IS200TREGH2B board executes emergency shutdowns for gas turbine protection. This emergency trip board also carries the revision code IS200TREGH2BDC . It monitors critical parameters and initiates rapid fuel cutoffs. The board serves as the last line of defense for turbine overspeed events.

Technical Specifications of GE IS200TREGH2B IS200TREGH2BDC

Component Count and Board Construction

This GE IS200TREGH2B board contains over 250 discrete components on its surface. You will find four high-reliability trip relays with forced guidance contacts. Furthermore, the board includes redundant power supply inputs for fault tolerance. The assembly also features diagnostic LEDs for each trip channel.

Interfaces, Energy Storage, and Voting Logic

The IS200TREGH2BDC revision provides screw terminal blocks for all trip wiring. Moreover, the board uses capacitors for coil hold-up during power dips. These capacitors store enough energy for 50 ms of operation. Each channel implements Triple Modular Redundancy (TMR) voting logic.

Functional Logic and Application Context

This Mark VI board receives trip commands from overspeed and vibration protection modules. It then energizes the trip coils to shut off fuel supply. The GE IS200TREGH2B requires two-out-of-three voting before activating a trip. Additionally, it continuously monitors coil continuity for open circuit conditions. Consequently, the board prevents false trips while ensuring genuine emergency response.

Installation and Environmental Limits

You must isolate the 24 V DC supply before servicing this trip board. The operating temperature range spans -30°C to +65°C . Furthermore, the board withstands 5 g vibration without contact opening. Always verify the IS200TREGH2BDC wiring against the trip schematic before power-up.
