The Model NPH pH and ORP Node is a LONWORKS®-compatible node that uses twisted pair communications. The NPH works with several different temperature compensation inputs and with pH or ORP sensors. These multiple-sensor input options allow for various sensors to be used. Temperature compensation is adjustable by pH per Celsius for use with various processes. Up to four NpH nodes may be installed on the 2000 series controller.

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 NpH is installed, not only will you be able to view additional inputs you will also be able to datalog information and control relays based on the external device.
