N420I 4-20 mA Input Node
The 4-20 mA input node (N420I) is a LONWORKS® Technology-compatible node that uses twisted pair communications. The N420I uses an externally powered 4-20 mA loop. This allows for various instruments to be used by the 2000 series controller. The N420I can be used to receive up to four channels of 4-20 mA input.
The N420I can be used with OSMONICS® Lakewood 2000 Series Controllers. It can be used on cooling towers, boilers, wastewater, reverse osmosis and other processes. Up to two N420I's may be used with the OSMONICS® Lakewood 2000 Series Controllers.
One Network Interface Node (NIN) per 2000 Series Controller is required to operate network nodes such as the N420I.
