Less wiring in your system ultimately reduces installation time as well as installation costs, making you up-and-running in no time. CA 622 communication module enables communication with up to 9 devices, such as variable frequency drives, soft starters, or energy meters, using RS 485 communication via a Modbus RTU protocol. Incorporating them in this way can reduce the need to install additional cables and ports.
Connect peripheral devices via the module’s RS 485 galvanic isolated communication port and access them via the same web interface as other equipment in the system.
Connecting the peripherals over RS 485, not only simplifies the installation, it also enables access to much more data and information than connected via discrete cables!
