Omron CJ1WSCU41V1 Serial Communication Module

The Omron CJ1W-SCU41-V1 Serial Communication Module is a plug-in two-port interface for Omron CJ Series PLCs that enables serial data exchange between the controller and external devices such as HMIs, sensors, barcode readers, printers, and other serial equipment. Mount this module in a CJ PLC rack to add two serial ports and support RS-232/RS-422/RS-485 communication (model dependent), with standard serial data speeds up to the model’s maximum. Connector options include DB9 or terminal block variants depending on the specific CJ1W-SCU41-V1 version, and it features status LEDs to indicate active communication. Common applications include packaging machines, conveyor systems, machine controllers, and factory floor setups that require legacy serial integration, retrofit, or expansion within Omron automation projects, designed for industrial temperature ranges and an industrial environmental rating.
