The Model N420I Node is a LONWORKS®-compatible node that uses twisted pair communications. It accepts four 4-20 mA inputs which can be tied into most 2000 series controllers. Up to two N420I nodes may be installed on the 2000 series controller for a total of eight 4-20 mA inputs.

One Network Interface Node (NIN) per 2000 Series Controller is required to operate network nodes such as the NDIG, and contain Rel 98 Firmware. All controllers shipped after 1 June 98 will have Rel 98 firmware.

Relay configuration and datalogging

After a N420I is installed, not only will you be able to view external 4-20 mA inputs you will also be available to datalog information and control relays based on the external device.
