Sensor 4-20mA 1W-UNI


4 to 20mA DC current converter for the 1-Wire UNI (RJ11) bus. Electrically isolated, sources current to power an external “sink” probe. The 1-Wire UNI (RJ11) output can be connected to Ares, Poseidon2 and other units.



Brand : HW-Group

Isolated DC current sensor for the 1Wire-UNI bus. Sensor for measuring currents in the 0–20mA range. It is typically used to connect an industrial probe with 4–20mA output – 2wire current loop (“sink”type). Sensor current output is processed in Poseidon2 or Ares units to ber accessible via LAN or GSM.

The sensor is equipped with 8-points calibrating table/curve to set measured output appropriate to related industrial sensors. The calibration process is supported by  1W-UNI USB calibrator.USB dongle.

For 4-wire industrial sensors 0-20mA use  alternative Sensor 0-20mA 1W-UNI.
