Omron CJ1W-CLK23 Controller Link Unit

The Omron CLK23 is a Controller Link communication module for CJ-series PLC systems, enabling high-speed, deterministic networking using a 2-wire twisted pair connection. Designed for factory automation systems requiring reliable and synchronized data sharing across multiple nodes, this CPU Bus Unit supports data transmission rates up to 2 Mbps and features a screw connector interface for robust, secure wiring.

The CJ1W-CLK23 is ideal for peer-to-peer communications, data link applications, and distributed control architectures, particularly in systems with multiple PLCs, HMIs, or SCADA nodes requiring cyclic and acyclic data sharing.
