The digital input node (NDIG) is a LONWORKS® Technology-compatible node that uses twisted pair communications to monitor any dry contact input. There are four input channels on each NDIG. In addition it can be used with open collector type water meters on the first two channels. SNVT's such as flow rate, total gallons/liters can be utilized. K factors for water meters or gallons/liters per contact allow for compatibility with most water meters.
