The CJ1W-CLK21-V1 unit is a controller link unit manufactured by Omron. It is designed to provide wired communication capabilities for various Omron programmable logic controllers (PLCs) in the CJ series. The CJ1W-CLK21-V1 unit is intended to be mounted on a DIN rail and features screw terminals for easy wiring connections. The CJ1W-CLK21-V1 unit supports all CJ series CPU units, and it supports seamless integration into existing setups. However, it does not support the Omron NJ system with a CPU or extension rack, nor the Omron NSJ system with an NSJ controller. Each CJ1 system can accommodate up to eight CJ1W-CLK21-V1 units, while the CP1H PLC system can accommodate up to two CJ1W-CLK21-V1 units. The CJ1W-CLK21-V1 utilizes wired communication with shielded twisted-pair cable and with Manchester code as the coding scheme, baseband code as the modulation technique, and flag synchronization for synchronization purposes. It offers different transmission rates, and the maximum transmission distance varies depending on the baud rate. For example, at 2 Mbits/s, the maximum transmission distance is 500 meters and at 500 kbits/s, the maximum transmission distance is 1 km. The CJ1W-CLK21-V1 unit is lightweight, weighing approximately 0.110 kg, and it consumes 0.35 A of current at 5 V in the PLC. It features an LED indicator to provide visual feedback and a unit number switch for easy identification and configuration. Additionally, there are two-pin DIP switches for setting the transmission rate. It does not need any installation devices. In summary, the CJ1W-CLK21-V1 controller link unit by Omron is a wired communication module designed for controller link communication applications with Omron CJ series PLCs.
