Module with 2 NTC inputs, 2 ditigal inputs and router
DB2-2NTC-IO-BOO
 |
Key features
|
The DB2-2NTC-IO-BOO 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.
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.
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.
