NTC Inputs Digital Inputs & Router


The ZR-TID-M can read the temperatures of 2 on board NTC inputs and the 2 digital inputs and send them at regular intervals to one of a Gateway of the 4-noks products family. This device may be configured to manage alarm thresholds when exceeding maximum or minimum levels of temperature.


This device can perform data transmissions automatically and immediately (regardless of configured sampling rate) in order to signal a status change in one of the two digital inputs. The device is supplied at 12-24 Vdc/Vac continuously; therefore it can also act as a repeater or a parent device for battery-powered sensors.
