  • SISNet communication ports for network connection
  • Status indicator LEDs for communication monitoring
  • Backplane or terminal connections for power and signal integration

Working Principle:
The KJ2222X1-BA1 receives SISNet network signals and regenerates or amplifies them to extend the communication distance. It acts as a signal repeater that maintains data integrity while allowing SISNet nodes to be located farther apart than the base network specification permits. This ensures reliable safety communication across large installations.

Installation Requirements:

  • Install the module in a suitable DIN-rail or panel mounting location
  • Connect SISNet network cables to the appropriate ports
  • Ensure proper power supply connection
  • Verify the extended network topology complies with SISNet specifications
  • Maintain environmental conditions within the module’s operating range

Usage Precautions:

  • Do not exceed the maximum extension distance specified for the SISNet network
  • Verify network signal quality after installation
  • Ensure proper cable shielding and routing for extended network segments
  • Do not disassemble the module as it contains no user-serviceable parts
  • Follow all safety system installation and commissioning procedures
