Working Principle Field signals enter analog and digital channels. The module samples, conditions, and isolates signals before sending over serial bus to the main controller. Output commands from controller activate internal relays or analog outputs to drive field devices. Diagnostics monitor wiring and channel health.
Installation Requirements
- Bulkhead or panel mount
- Tighten waterproof glands
- Shielded marine cable
- DC24 V supply

- Configure module address after power-up
- Classification society acceptance
Precautions
- Do not open housing in humid area
- Keep glands sealed
- Verify channel wiring
- Store spares in dry packaging
- Periodically test I/O channels
- Replace gasket at major overhaul
- Follow classification inspection intervals
