Current sensor Sensor 0-20mA 1W-UNI, 0-20 mA DC converter, electrically isolated, RJ11 1-Wire UNI - HW group 600566

Plenty of industrial probes only speak current loop, while the monitoring unit in the plant room does not. The Sensor 0-20mA 1W-UNI converts that signal for the 1-Wire UNI bus with ±2 % accuracy across the full range, galvanically isolated and with up to 8 calibration points.

Benefits

• Galvanic isolation: the 0-20 mA input is electrically isolated from the 1-Wire UNI bus, so ground potential differences between probe and monitoring unit do no harm.
• Real units instead of mA: an 8-point calibration table and unit conversion inside the sensor deliver readings in litres, bar or ppm.
• Protected input: a 63 mA fuse guards the measuring input.
• Simple wiring: two RJ11 sockets let you daisy-chain further sensors on the same bus.
• No separate supply needed: powered from the 1-Wire UNI bus at 5 V and 20 mA, up to 2 sensors per active port.

Technical data

Applications

• Tank level measurement, for example for standby diesel generators in data centers
