Working Principle

The module acts as the main controller of the remote I/O bus, polling slave devices on the bus according to the defined communication protocol to collect remote I/O signals and issue control commands. The electrical isolation circuit blocks the electrical connection between the field side and the system side, preventing ground loops and surges from damaging system equipment.

Installation Requirements
  • Install in the corresponding slot of a 2005 system rack
  • Use shielded twisted-pair cable for communication, with shield grounding at both ends
  • Install matching termination resistors at bus terminals
  • Route cables away from strong electromagnetic interference sources
Usage Precautions
  • Do not plug or unplug communication cables while power is applied
  • Do not set duplicate device addresses on the bus
  • Inspect communication cable connections periodically
  • Install repeaters when communication distance exceeds the maximum limit
