Key features
|
The DB2-2NTC-B00 is a battery powered ZigBee device which can read at the same time the temperature with the 2 on board NTC inputs and the 2 digital inputs and send them at regular intervals to one of a Gateway of the Digitron products family.
This device may be confi gured to manage alarm thresholds when exceeding maximum or minimum levels of temperature. It is also possible to adjust the sampling and data transmission rate to improve battery life.
This device can perform data transmissions automatically and immediately (regardless of confi gured sampling rate).
in order to signal a status change in one of the two digital inputs.
