OMRON CP1W-SRT21 CompoBus/S I/O Link Unit for CP Series PLC

The OMRON CP1W-SRT21 (CP1W-SRT21) is a CompoBus/S I/O link unit designed for expansion with OMRON CP-series programmable logic controllers, including CP1H, CP1L, and CP1E CPU units. Functioning as a high-speed slave station on a CompoBus/S sub-network, this communication interface module connects seamlessly to the PLC expansion bus to facilitate distributed I/O data exchange between the host controller and remote field devices. It provides an efficient link consisting of eight input points and eight output points assigned directly to the PLC internal memory, eliminating complex point-to-point field wiring. The unit mounts directly onto the CPU unit or adjacent expansion modules using an integrated expansion connector, making installation straightforward in compact control cabinets. Engineered for industrial automation environments such as packaging machinery, material handling systems, and assembly lines, the module enables deterministic remote control and rapid cycle times. The OMRON CP1W-SRT21 ensures reliable operation across distributed manufacturing networks, reducing field wiring costs while optimizing system architecture.
