Working Principle:
The 1C31181G01 receives electrical data from the local I/O bus via its RS485 interface and converts it into optical signals for transmission to up to two remote I/O nodes through its fiber optic ports. In the reverse direction, it receives optical signals from remote nodes and converts them back into electrical data for the local controller. The onboard 24 VDC to 5 VDC power conversion ensures proper operating voltage for the internal circuitry.
Installation Requirements:
- Mount the card on a DIN rail or within a compatible control rack
- Connect the RS485 interface to the local I/O bus
- Connect fiber optic cables to the two remote node ports
- Ensure proper power supply connection (24 VDC input)
- Maintain operating temperature within the specified range
- Follow Ovation system grounding and cable routing guidelines
Usage Precautions:
- Verify fiber optic cable polarity and cleanliness before connection
- Do not exceed the specified input voltage range
- Ensure proper ventilation around the module for heat dissipation
- Perform communication verification after installation
- Handle fiber optic connectors with care to prevent contamination
- The module contains no user-serviceable parts and shall not be disassembled
