IS200TTURH1CFD GE Mark VI Turbine Terminal Board
H2 Overview
IS200TTURH1CFD Product Introduction
IS200TTURH1CFD is a GE terminal interface board belonging to the Mark VI Speedtronic turbine control system. It acts as a signal termination and relay interface board, working in coordination with PTUR speed board and VTUR voltage board to complete generator synchronization, breaker control and turbine protection signal routing.
This terminal board routes speed pickup signals, generator PT voltage signals, breaker status and relay control signals between field side and the Mark VI main controller. It integrates terminal blocks, signal conditioning circuits and protection relays, isolating high-voltage field signals from low-voltage logic circuits. It is a vital hardware component for gas and steam turbine grid synchronization, breaker closing logic and turbine protective trips in power plant control racks.
The board includes on-board fuses and relay outputs for trip circuits, built-in fault monitoring to detect loose wiring, loss of input signals and relay failures. It is designed for continuous heavy-duty operation in power plant cabinets with strong electromagnetic interference.
