I previously testing the following wiring:1. The I/O module has the 4-20mA (-) connect to the L(-) terminal. If the 4-20mA is not an isolated output (which I doubtt given that terminals 2 & 3 are tied together on the transducer), you could have a ground loop problem between the transducer DC supply/transducer 4-20mA return and the I.O L(-).
Is there some reason you're not using the I/O modules L(+) for DC power to the transducer? The DCT100 needs 2VA or 85mA
Got a new DCT and did the same testing I did above, this time I am getting 0.0-0.02mA. I have also tried using the +24V and GND from my PLC module for my + and -Power, with no output. I am using a HRP-150-24 PSU, is there some issue with the power supplies I am using or a different way I should try measuring this?I removed the display unit and +Power and -Power was connected to +V and -V of my 24V PSU. Red lead on MM on +Out and Black COM lead on MM on the -Out. I connected to power and confirmed it was receiving 24V
