GE IS200TRPGH1B Mark VI Primary Trip Terminal Board

The GE IS200TRPGH1B board terminates critical trip circuits for turbine protection. This primary trip terminal board connects overspeed relays to the protection system. It provides reliable wiring termination for emergency shutdown functions. The board ensures fail-safe operation during turbine overspeed events.

Technical Specifications of GE IS200TRPGH1B

Component Count and Board Construction

The GE IS200TRPGH1B board contains over 130 discrete components. You will find four high-reliability trip relays with forced guidance contacts. Furthermore, the board includes suppression diodes for each relay coil. The assembly also features status LEDs for every trip channel.

Interfaces, Energy Storage, and Signal Routing

The GE IS200TRPGH1B 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 includes a dedicated test point for troubleshooting.

Functional Logic and Application Context

This Mark VI board routes trip signals from the protection module to field devices. It implements two-out-of-three voting logic for each trip channel. The GE IS200TRPGH1B also monitors coil continuity for open circuit conditions. Additionally, it provides visual feedback through channel LEDs. Consequently, the board ensures reliable emergency shutdowns while preventing false trips.

Installation and Environmental Limits

You must isolate the 24 V DC supply before servicing this terminal board. The operating temperature range spans -30°C to +65°C . Furthermore, the board withstands 5 g vibration without contact opening. Always verify the GE IS200TRPGH1B wiring against the trip schematic before power-up.
