hi guys, im having difficulty with this issue, in trying to understand why this happens. ok let me begin....
im using a 4 wire instrument, current signal is being connected back to the plc analog i/p card. but no mA signal at the plc, so this obviously forces me to use a loop isolator.
so why does this happen? and how do i refrain from using a loop isolator, pls help
