Mark A Posted September 5, 2012 Report Share Posted September 5, 2012 I am setting up a V130 to control an oil system, which will use a flow meter with a 4-20 ma input and an ultrasonic sensor also with a 4-20 ma. I have set up AN0 up as a 4-20 ma analog input in the hardware configuration. When I connect my 4-20 signal to terminal #4 my mili amp meter shows 3.5 ma. no mater what I do. I have checked my device and it puts out the proper 4-20 range but as soon as I connect it I get 3 + ma. I have taken the back off and checked the jumpers and they are all in the B position. I have several PLC's running with an analog input and have never had any problems before. What am I missing? Quote Link to comment Share on other sites More sharing options...
