Although this a 4 wire AI module, it expects that its DC power supply will power 4-wire field devices, because in doing so, there is little or no likelihood of a common mode, ground loop problem. However, When you use an external power supply, the prospect of creating a ground loop is quite likely. So there's no fixed answer for your situation, you'll have to try it and see. manual (4-wire wiring on page 12) |

Thanks for the reply, but you said "Signal (+) to In+ and Signal (-) to nA", but my transmitter has only DC(+)/DC(-) and S pin (4-20mA), not S(+) and S(-). I am bit confused :( |
