Key Features

1. High-Density Digital I/O: 32 input and 32 output channels support large-scale digital signal collection and control for complex turbine systems.
2. Galvanic Isolation: Opto-isolation between field circuits and internal logic (1500 V AC) protects the board from voltage spikes and EMI interference.
3. Real-Time Monitoring: 10 LED indicators provide immediate visual feedback for channel status (ON/OFF, fault), simplifying on-site troubleshooting.
4. Flexible Configuration: 8 jumpers allow users to set board addresses, communication modes, and input/output types without firmware changes.
5. IONET Communication: Connects to the Mark V system via high-speed IONET fiber-optic network, supporting redundant data transmission for enhanced reliability.

Application Scenarios

• Turbine Control: Gas/steam/hydro turbine systems for monitoring limit switches, pressure switches, and temperature switches; controlling solenoid valves, relays, and motor starters.
• Power Plants: Thermal, combined-cycle, and hydroelectric power stations for generator synchronization, breaker control, and safety interlock monitoring.
• Oil & Gas: Refineries, pipelines, and LNG facilities for turbine-driven equipment control and safety system monitoring.
