GE IS200TREGH1B IS200TREGH1BDB Emergency Trip Board

The GE IS200TREGH1B IS200TREGH1BDB Emergency Trip Board MK VI IS200 executes immediate turbine shutdown upon fault detection. You will find this board critical for personnel and equipment safety. Its redundant design guarantees trip execution even with single component failure.

Dimensions, Weight, and Physical Layout

This emergency trip board measures 17.5 cm in length and 12.8 cm in width. Its height reaches 2.4 cm including all safety-rated components. The total weight stands at 0.52 kilograms for secure rack mounting. A conformal-coated PCB resists moisture and chemical exposure effectively.

Trip Interfaces and Component Count

The GE IS200TREGH1B IS200TREGH1BDB Emergency Trip Board MK VI IS200 provides four independent emergency trip relay outputs. Each relay features forced-guided contacts for SIL-3 safety integrity level. You also receive six dedicated trip request inputs from protection modules. In total, this board contains 165 individual electronic components. These include 4 safety relays, 6 optocouplers, and 98 monitoring resistors.

Energy Storage and Power Parameters

A 3.3V supercapacitor bank provides onboard energy storage for 72 hours. This backup maintains trip history and timestamp data during power loss. The board draws 5.5 watts from a nominal 24V DC supply. Peak inrush current stays safely below 2.5 amperes.

Memory, Processing, and Environmental Limits

You get 64 MB of flash memory for trip logic configuration storage. The board also includes 32 MB of SRAM for real-time fault recording. A 200 MHz dedicated processor handles independent trip verification. Therefore, the operating temperature ranges from -25°C to +70°C. Storage temperatures extend from -40°C to +85°C without degradation.

Connectors, Diagnostics, and Additional Features

Two 40-pin ribbon cable headers connect to protection termination boards. A single 10-pin diagnostic port provides real-time trip status monitoring. For similar static trip system emergency protection, see the RMS-TSG-TZ-C model from the same manufacturer. However, this emergency trip board specializes in failsafe turbine shutdown exclusively. The board also includes a hardware watchdog timer for independent safety verification. Mean time between failures (MTBF) exceeds 180,000 hours in continuous use.
