OMRON CJ1W-DRM21 Product Description

OMRON CJ1W-DRM21 is a DeviceNet communication unit for CJ1 series PLC, supporting both master and slave functions for industrial DeviceNet fieldbus network. It enables connection with remote I/O modules, inverters, sensors and other DeviceNet compatible devices to build distributed automation control systems.

This unit delivers stable fieldbus communication for DeviceNet industrial networks. The fieldbus communication supports multiple baud rates and adjustable transmission distance. The fieldbus communication can manage up to 63 slave nodes under master mode. Reliable fieldbus communication realizes synchronous real-time data exchange across the whole network.

The dual master-slave function achieves flexible network configuration. Network configuration allows the module to act as master and slave simultaneously in one system. Network configuration supports memory card storage for parameter backup and fast commissioning. Adjustable network configuration fits small and medium-sized distributed control projects.

Built-in monitoring logs provide effective network diagnosis. Network diagnosis records communication error information and operating status continuously. Network diagnosis uses LED indicators to show network faults intuitively. Sensitive network diagnosis helps engineers quickly locate wiring or node failures.

OMRON CJ1W-DRM21 is widely used in packaging machinery, material handling lines and assembly automation equipment. It adopts plug-in backplane installation, supports remote I/O control and explicit message communication. It features compact size, strong anti-interference performance and compatibility with CX-Integrator configuration software. It perfectly matches CJ1 series CPU modules and complies with international industrial fieldbus standards.
