I have a couple of older installs that I am converting from S5 PLC's. On several of the honeywell valve actuators there were 135 ohm to current converters made by Barber -Coleman. I am in deserate need of wiring diagrams or a link to a site. I am not sure but the possible model # is MPR-5633.I will have a better identification of these as soon as I get on site to look at one.
I know thi is vague - just thought I'd get the wheels spinnin
