GE IS200SRTDH2ACB is an original RTD terminal board developed for GE Mark VI turbine control system. It receives temperature signals from RTD sensors, delivers accurate signal conditioning and stable data transmission for gas and steam turbine temperature monitoring and protection.

GE IS200SRTDH2ACB is a high-reliability simplex RTD input terminal board belonging to GE Mark VI turbine control platform, widely deployed in power generation turbine control cabinets. It acts as the interface between field RTD temperature sensors and the Mark VI I/O pack, responsible for receiving, filtering and forwarding resistance temperature signals to the main control unit for real-time temperature calculation, monitoring and equipment protection logic. 

This board supports Pt100 and other common RTD sensors with 2-wire or 3-wire wiring modes. Built-in noise suppression and signal filtering circuits effectively filter electromagnetic interference from power equipment, motor drives and high-voltage cabinets, preventing signal distortion and false temperature alarms during continuous heavy-duty operation. It adopts industrial-grade PCB substrate and carefully screened electronic components, offering outstanding shock resistance, vibration resistance and wide temperature adaptability to fit the harsh environment inside turbine control rooms. Equipped with organized screw terminal blocks and dedicated backplane connector, it provides neat and convenient field wiring, lowers wiring mistakes during commissioning and overhaul. 

The compact board structure perfectly fits the standard Mark VI rack layout, supporting quick plug-and-play replacement for system maintenance and retrofit projects. Every unit passes comprehensive factory aging test, continuity inspection and signal accuracy calibration before delivery to guarantee stable long-term running and low failure rate. It undertakes critical temperature monitoring tasks for gas turbines, steam turbines and auxiliary power equipment. When abnormal temperature rises are detected, it transmits alarm signals to the controller to trigger protection interlock, avoiding turbine overheating damage and unplanned unit shutdown. It is a vital spare part for power plant Mark VI system maintenance, upgrade and reconstruction projects, maintaining full compatibility with original Mark VI hardware architecture without complicated program modification. Widely used in thermal power, combined cycle power station and oil & gas energy industries.
