Key features
|
DB2-2EO-2RL is provided with a thermal resistor input, two digital inputs and two relay outputs. It can perform the function of thermostat in programmable warm-cold operating mode with relay outputs and manages alarms based on preconfi gured thresholds. Moreover it sends data at regular intervals to a Gateway belongings to the Digitron products family.
The thermostat functionality may be disabled; in this situation inputs and outputs are directly managed by PLC or SCADA connected to the Gateway.
The device is supplied at 24Vdc/24Vac continuously; therefore it can also act as a repeater or a parent device for battery-powered sensors.
