• Power & Electrical: 24VDC standard input, power consumption ≤20W; PCB with conformal coating for EMI resistance and vibration tolerance, suitable for industrial field environments

• I/O & Interfaces: Multi-channel analog/digital I/O for sensor, encoder, and actuator signal access; RS‑232/RS‑485 communication interfaces for data exchange between system modules and host computers

• HMI & Diagnosis: Onboard 10 LED indicators for real-time status and fault code display, enabling on-site quick troubleshooting; field-reprogrammable and soft-reset supported for system recovery without shutdown

• Environment & Physical: Operating temperature -40℃~+85℃; dimensions approx. 200×55×120mm, weight approx. 0.39kg; standard embedded mounting for direct integration into Mark V system racks

3. Core Functions

• Drive & Exciter Control: Executes precise speed, torque, and position control algorithms for motors/exciters, processing analog/digital signals to ensure stable and reliable power output

• Signal Conversion & Processing: Performs bidirectional conversion between analog (temperature, pressure, flow) and digital signals from sensors, ensuring accurate data transmission and computation

• System Communication & Coordination: Acts as a system communication node, managing internal bus and external device interaction to ensure collaborative operation of Mark V turbine control system modules

• Fault Diagnosis & Protection: Monitors real-time operating status, triggers alarms and protection logic for overvoltage, overcurrent, and overtemperature faults to reduce equipment damage risk

4. Typical Applications

• Drive and exciter control systems for gas turbines, steam turbines, and combined-cycle power plants

• Spare replacement, upgrade, and maintenance of Mark V control systems, as well as motor/drive control units in industrial power units and chemical processes
