Working Principle PT100, pressure transmitter, and speed sensor signals enter the module. The CPU compares measured values to setpoints. Limits trigger alarm or shutdown relays. Events are logged with timestamps. CAN bus uploads data to the main control display. Sensor wire-break is diagnosed.
Installation Requirements
- Panel or rail mount
- Waterproof cable glands tightened
- Shielded sensor cables
- DC24 V supply
- Grounding
- Temperature -25 °C to +70 °C
- Set protection values after power-up
- Classification society acceptance
Precautions
- Handle sensor wire-break promptly
- Do not modify protection values arbitrarily
- Periodically perform function tests
- Store spares in dry packaging
- Disconnect power before service
- Check waterproof cable glands
