IS200WETAH1AEC is the complete part number. It is a dedicated interface PCB board for GE Mark VI gas turbine and steam turbine control systems.

2. Main Functions

1. Designed for GE Mark VI turbine control system and acts as an internal signal transition interface board.
2. Realizes signal matching, level conversion and signal isolation between main control boards, external equipment and various acquisition boards.
3. Performs routing and distribution of multiple control signals, feedback signals and communication signals.
4. Built-in filter circuits reduce electromagnetic interference from industrial sites and ensure stable signal transmission.
5. Equipped with standardized terminals and signal channels to simplify internal wiring connection of the system.
6. Exchanges data via the system backplane and assists in transmitting interlock signals, measurement signals and control commands.
7. Supports hardware circuit self-testing and reports circuit fault information in coordination with system diagnosis functions.

3. Applications

1. Applied to control systems of gas turbine and steam turbine generator units based on GE Mark VI platform.
2. Mainly deployed in control cabinets of turbine units in thermal power plants and combined-cycle power stations.
3. Builds signal links inside the control system to connect functional modules with different roles.
4. Used for signal transition of unit speed monitoring, excitation control, protection interlock and process parameter acquisition loops.
5. Widely adopted as key spare parts for maintenance and fault replacement of power plant control systems.
6. Ensures reliable signal transmission of turbine control loops and prevents false alarms and unplanned unit shutdown caused by signal distortion.
