CLX analog output module

Hi all,

I cannot find any analog output module for ControlLogix that can output a negative current: -20 mA --> +20 mA ???

Did I miss something ???

No, you haven't missed anything - there isn't one.

You could get +/- 10mA from a voltage output card (minimum load = 1 kOhm).

Better still, use a +/- 10V output and drive a suitable signal conditioner/isolator - someone will jump in and give names and recommendations

phoenix contact makes a really nice configurable conditioner. I have used it several times and it will do almost anything with dip switch changes. I don't remember the price, but I think it was around $350.
