OMRON CS1W-SCB21-V1 Serial Communication Board for CS1 Series PLCs

The OMRON CS1W-SCB21-V1 is a serial communication board designed for use with OMRON CS1 series programmable logic controllers. Installed directly into the inner board slot of a CS1 CPU unit, this communication board expands the system's serial connectivity by providing two independent RS-232C ports. It enables versatile industrial data exchange with peripheral devices, operator interfaces, bar code readers, temperature controllers, and third-party automated machinery. The board supports multiple standard communication protocols, including Host Link, Protocol Macro, 1:N NT Link, and serial gateway modes, allowing custom communication sequences without complex PLC ladder programming. Each RS-232C port connects via standard D-sub 9-pin connectors, facilitating dependable point-to-point connections across factory automation networks. By offloading serial handling directly from the main processor, the CS1W-SCB21-V1 ensures rapid data throughput and consistent CPU cycle times. It is widely utilized in manufacturing, packaging, process control, and material handling systems requiring seamless integration between CS1 automation architectures and serial field equipment.
