- High and low shaft speed monitoring
- Structural Features
- Advanced epoxy resin coating for corrosion and environmental hazard resistance
- High-grade aluminum material for strength and heat dissipation
- Three TCEA boards (X, Y, Z processors) constitute the Protective Core P1
- Signals from X-position board transmitted via JX1 to STCA board in R1 core over IONET
- Application Scenarios
- Gas turbine protection and emergency shutdown
- Steam turbine safety systems
- Power generation critical control
- Compatible with Mark V / Vi / Vie, EX2100e excitation control, HMI/SCADA integrations
- Installation Requirements
- Install in the Protective Core P1 of Mark V LM series turbine control systems
- Connect JX1 and JX2 for daisy-chained IONET communication
- Properly seat J7, JK, JL, and JW connectors per wiring diagram
- Ensure input voltage within 24–60 V DC range
- Usage Notes
- Maintain operating temperature within -40°C to +60°C
- Military-grade connectors rated for 10,000+ mating cycles
- Verify jumper and configuration settings match system requirements before power-up
- Handle with ESD protection; epoxy coating provides environmental resistance but board remains static-sensitive
