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.
Technical Details
MPN: 820KCG2485. Slots used on docker: 1

Frequently Asked Questions
Do I need the Docker to use this module?
Yes — the Docker Interface clips to the rear of the N20K48 and provides the slots the ClickNGo modules fit into.
Can the N20K48 act as a Modbus Master with this module?
No — this module configures the controller as a Slave device, responding to requests from a Master such as a PC, PLC, or SCADA system.
What other ClickNGo modules are available?
See our N20K48 Docker Interface listing for the full range of compatible modules.
Industry Applications
- SCADA/PLC Integration — connects the N20K48 into an existing Modbus serial network.
- Centralised Monitoring — read process data and status remotely from a supervisory system.
- Multi-Controller Installations — network multiple N20K48 units on a shared RS485 bus.
