The Omron CS1W-BC083 Backplane Connector Unit is the eight-slot backbone for CS1 series PLC racks, providing module interconnection between the CS1 CPU, power supply, and I/O modules. It mounts in a panel rack and distributes power across connected modules while enabling internal bus communication. Widely used in control panels, manufacturing lines, process automation systems, and industrial machinery to secure stable PLC rack communication. Operating from 0°C to 55°C, the CS1W-BC083 supports CS1 CPU, power supply, and I/O modules in CS1 rack configurations. Common replacements include CS1W-BC053 and CS1W-BC103.
