Material Composition & Structural Features:
- PCB Assembly: Multi-layer printed circuit board with conformal coating against moisture and corrosive gases.
- Connectors: Spring-loaded or screw-type terminals ensuring secure field wiring.
Working Principle:
Receives raw electrical signals from field sensors, conditions them through isolation and amplification circuits, and transmits the digital data to the controller via the system backplane.
Installation Requirements:
- Install in a well-ventilated control cabinet with ambient temperatures within specified limits.
- Use shielded twisted-pair cables for all field signal connections.
Usage Precautions:
- Ensure proper grounding of signal shields at the cabinet ground bar.
- Never disconnect field wiring while the module is powered to prevent transient voltage spikes.
