Working Principle: The module acts as a data gateway between the 3500 monitoring system and the external world. The main card (288055-01) handles backplane communication and Modbus RTU functions. The Ethernet daughter card (146031-01) plugs into the main card, adding TCP/IP network capability. Together they collect machinery data from the rack and transmit it to external control and information systems.
Installation Requirements:
- Install in the designated slot of the 3500 rack
- Ensure the daughter card is properly seated in the main card
- Ethernet cable should be shielded CAT5 or better
- wiring must observe proper termination and polarity
- Verify firmware compatibility with rack configuration software
Use Precautions:
- The complete module consists of two physical parts: main card and daughter card
- Both components must be properly installed for full functionality
- Ethernet network configuration must match plant network requirements
- network termination must be properly configured
- Replace only with compatible main card and daughter card combinations
