Novus N20K48 - CG-485 ClickNGo Module - RS485 Comms

The CG-485 ClickNGo module clips into the N20K48 Docker Interface (sold separately) and adds RS485/Modbus communication terminals, allowing data exchange between the N20K48 and a wider serial network. The controller acts as a Slave device, responding to requests from a Master — computer, PLC, or SCADA.

Please remember to purchase the N20K48 Docker Interface, which is required to fit ClickNGo modules to the N20K48 controller.
