Function

This isolated barrier is used for intrinsic safety applications. It converts a 2-wire voltage or current in the hazardous area to a 4 mA ... 20 mA signal
in the safe area.
The device can be used to double signals in 20 mA measurement circuits due to the limited current signal input load of 50 Ω.
DIP switches and potentiometers make field calibration easy.
Since this isolator is loop-powered, use the technical data to verify that the proper voltage is available to the field devices.
