CJ Series CompoBus/S Master Station Unit for Deterministic Device Network Control
The Omron CJ1W-SRM21 is a dedicated CompoBus/S Master Station Unit designed for integration with CJ Series Programmable Logic Controllers (PLCs) and Programmable Automation Controllers (PACs). This industrial network controller module establishes a high-speed, deterministic master-slave network, enabling precise synchronization and control of up to 32 remote I/O and sensor/actuator slave devices. Operating on a 24VDC power supply, the SRM21 master unit facilitates rapid data exchange with a maximum 1.5ms communication cycle time for 32 points, optimizing performance in synchronized motion control, assembly, and packaging applications. Its direct integration into the CJ Series CPU rack simplifies system architecture, reducing wiring complexity and installation time while providing reliable, noise-resistant communication via dedicated CompoBus/S cables for robust operation in demanding industrial environments.
