4-20mA sensors

The Hydro-Logic

®

Flexi Logger 100 has one 4-20 mA input with 12V switched

power up to 120mA. It can be used for either loop-powered or 3-wire 4-20mA
sensors.

Loop powered sensors are wired as shown below. If there is a vent tube, cut it off
inside the connector body and ensure it is not blocked.

Process signals, where the loop is powered, should be wired as shown. A loop
isolator should be used.
