2. Core Product Functions

1. Electrical-optical signal conversion: Convert DS100 PBC electrical bus signals to optical fiber signals, realize long-distance interconnection between separated control racks, eliminate signal attenuation caused by long copper cables.
2. Strong anti-EMI interference: Optical transmission completely isolates electrical interference from high-power equipment such as inverters, motors and power circuits, ensuring stable bus communication in high-noise industrial sites.
3. Rack activation & configuration management: Complete remote rack activation by writing specified address parameters, support virtual rack monitoring and expansion bus signal distribution across multiple racks.
4. Real-time bus status monitoring: Front panel LED indicators display power status, fiber link status and bus communication faults, quickly locate link disconnection or signal loss problems.
5. Multi-rack system expansion: Realize distributed expansion of DCS/PLC control system, expand the number of I/O racks without loss of communication real-time performance.
6. Hot swap compatible rack design: Matched with ABB standard automation racks, support non-stop maintenance replacement of the modem module in partial system scenes.

3. Application Scenarios
