Performance Parameters
- Relay Capacity: Rated for industrial switching currents.
- Response Time: Fast thermal response to prevent equipment overheating.
Material Composition
- PCB: High-reliability, multi-layer board with conformal coating.
- Components: Heavy-duty electromechanical relays and solid-state drivers.
Structural Characteristics
- Form Factor: Standard Mark V board size.
- Connectors: High-density backplane edge connectors.
Working Principle
Receives temperature or status signals from the Mark V processor, executes control logic, and energizes relay coils to switch high-power circuits that drive fan motors or signal external panels.
Installation Requirements
- Follow Mark V installation manuals for proper board placement.
- Ensure all relay output cables are properly shielded and grounded.
Usage Precautions
- Never disconnect relay wiring while the system is energized.
- Inspect relay contacts periodically for arcing or pitting.
