The TVA a transducer for a Pt100 temperature sensor. PT 100 is shot as a four-wire and operated by the device with approx. 2.2 mA constant current. The device has a broken wire detection, monitoring the connected sensor.
Is about 24 VDC powered. The negative voltage of power supply and the zero point (0 V) have the same potential. The analog output can be maximum 10 V at 20 mA. The maximum load is 500 W.
The connections are made through 2-pole Pluggable screw terminal (max. 2, 5 mm²). The TVA is contactless and thus maintenance-free. He is to be protected against moisture and stubborn dirt. The installation position is arbitrary.
