Interface for sensors, valves, pumps, circuit breakers, output control commands.

Power Supply: 24 VDC (18‑32 VDC) Communication: Redundant CAN‑Bus fieldbus Mounting: DIN rail Protection Class: IP20 Operating Temperature: ‑25℃ ~ +70℃ Weight: Approx. 390‑650g Certification: DNV‑GL marine approved Lifecycle: Discontinued by OEM. No brand‑new original orders. Only used and refurbished spare parts available.

Main Functions

1. Digital DI input acquisition, relay DO output; some variants support analog signal processing.
2. Full channel galvanic isolation for harsh marine EMI environment.
3. Communicate with Mega‑Guard main controller via redundant CAN‑Bus.
4. On‑board LED status indicators, built‑in self‑diagnostics for fault reporting.
5. Signal interface for engine room alarm, genset monitoring and propulsion auxiliary systems.

Compatibility Notes

1. Exact part number 98.6.032.702 must be matched. Verify hardware Rev (C/D/Da) and board ID. Different hardware revisions are not freely interchangeable; system re‑configuration may be required.
2. Dedicated for Mega‑Guard system; cannot run standalone, must work with Praxis main controller unit.
3. Prefer identical Rev version for replacement; perform bus scan and channel testing after installation.

Procurement Notes

• Check both outer housing label and PCB silkscreen 20.2.610.710.
• Confirm hardware revision and board ID.
• Inspect terminals and bus connectors for corrosion (common failure on marine used units).
