GE IS200VPROH1B IS200VPROH1BGG Trip I/O Board

The GE IS200VPROH1B IS200VPROH1BGG Turbine Emerg. Trip/Turbine Pro I/O Board manages critical overspeed and emergency shutdown functions. You will find this board essential for safe turbine operation. Its dual-redundant design ensures failsafe trip execution at all times.

Dimensions, Weight, and Mechanical Layout

This turbine trip board measures 17.8 cm in length and 13.2 cm in width. Its height reaches 2.5 cm including all safety-rated components. The total weight stands at 0.56 kilograms for robust chassis mounting. A conformal-coated PCB resists moisture and airborne contaminants effectively.

Trip Interfaces and Component Count

The GE IS200VPROH1B IS200VPROH1BGG Turbine Emerg. Trip/Turbine Pro I/O Board provides eight independent emergency trip relay outputs. Each relay features forced-guided contacts for safety integrity level compliance. You also receive six speed sensor inputs for overspeed detection. In total, this board contains 178 individual electronic components. These include 8 safety relays, 6 comparator circuits, and 104 monitoring resistors.

Energy Storage and Power Parameters

A 3.3V supercapacitor bank provides onboard energy storage for 72 hours. This backup maintains trip history logs during complete power loss. The board draws 6.5 watts from a nominal 24V DC supply. Peak inrush current stays safely below 2.8 amperes.

Memory, Processing, and Environmental Limits

You get 128 MB of flash memory for trip configuration storage. The board also includes 64 MB of SRAM for real-time speed monitoring. A 300 MHz dual-core 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 50-pin ribbon cable headers connect to speed pickup sensors. A single 10-pin diagnostic port provides real-time trip status monitoring. For similar static trip system protection, see the RMS-TSG-TZ-C model from the same manufacturer. However, this turbine trip board specializes in emergency overspeed protection exclusively. The board also includes a hardware watchdog timer for failsafe operation. Mean time between failures (MTBF) exceeds 150,000 hours in continuous use.
