Description
GE IS200TPROH1BCB Mark VIe Protect terminal board
Product Overview
The GE IS200TPROH1BCB is a protective terminal board purpose-built for the GE Speedtronic Mark VIe turbine control system. It acts as the critical signal interface between field speed sensors and the VPRO (Voting Processor) board, serving the independent emergency overspeed and synchronization protection loops.
This board conditions, buffers and routes turbine speed pulse signals to the voting protection processor. It works in tandem with TREx and TREG boards to form a comprehensive, redundant emergency protection architecture. Designed for rugged turbine hall environments, it delivers stable, noise-immune signal transmission for mission-critical turbine safety functions.
Core Product Features
- Delivers conditioned speed and timing signals to the VPRO voting processor for independent overspeed protection logic
- Supports an MPU pulse rate range from 2 Hz to 20 kHz, matching common turbine speed sensor outputs
- Powered by 28 VDC directly from the system backplane, requiring no external field power supply
- Integrated signal isolation and filtering suppresses electrical noise and ground loop interference from field wiring
- Works with TREx and TREG modules to form a layered, redundant emergency protection system
- Front-panel status indicators provide at-a-glance visual feedback for on-site diagnostics
- Industrial-grade conformal coated PCB withstands dust, humidity and temperature extremes in power plant environments
- Standard Mark VIe plug-in form factor enables direct drop-in replacement and fast on-site maintenance
