Isolated Two-Wire Current Loop Circuit (XTR101, ISO100)

Published:2011/5/20 9:35:00 Author:Robert | Keyword: Isolated, Two-Wire, Current Loop | From:SeekIC

As shown in the picture below, this circuit uses the XTR101 in conjunction with isolated amplifier ISO100 to change and amplify the 4~20mA current to be +1~+5V output voltage. At the same time it should have isolation on the power. This circuit has a excellent anti-jamming feature, which can be used in the case of long-distance signal transmission or the scene where has a large disturbance.
