MeloAuto-Trusted PLC & DCS Parts Supplier
The GE IS200VTURH2B IS200VTURH2BAC Turbine Protection Circuit Board monitors critical turbine parameters for safe operation. You will find this board essential for overspeed, overtemp, and vibration protection. Its redundant architecture guarantees failsafe shutdown when necessary.
Dimensions, Weight, and Physical Layout
This turbine protection board measures 18.2 cm in length and 13.5 cm in width. Its height reaches 2.4 cm including all safety-rated components. The total weight stands at 0.58 kilograms for secure rack mounting. A conformal-coated PCB resists moisture, dust, and chemical contaminants effectively.
Protection Interfaces and Component Count
The GE IS200VTURH2B IS200VTURH2BAC Turbine Protection Circuit Board provides eight independent emergency trip relay outputs. Each relay features forced-guided contacts for SIL-3 compliance. You also receive twelve analog monitoring inputs for temperature and pressure. In total, this board contains 212 individual electronic components. These include 8 safety relays, 12 analog front-ends, and 132 monitoring resistors.
Energy Storage and Power Parameters
A 3.3V supercapacitor bank provides onboard energy storage for 72 hours. This backup retains trip history and configuration during power loss. The board draws 6.8 watts from a nominal 24V DC supply. Peak inrush current stays safely below 2.9 amperes.
Memory, Processing, and Environmental Limits
You get 128 MB of flash memory for protection logic storage. The board also includes 64 MB of SRAM for real-time parameter monitoring. A 300 MHz dual-core processor handles independent protection channel 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 and temperature sensors. A single 10-pin diagnostic port provides real-time protection status. For similar static trip system protection, see the RMS-TSG-TZ-C model from the same manufacturer. However, this turbine protection board specializes in comprehensive turbine safety exclusively. The board also includes a hardware watchdog timer for failsafe operation. Mean time between failures (MTBF) exceeds 150,000 hours in continuous use.
