Hi everyone!
I have a micrologix 1400 with an 1762-OF4 analog input module and I'm trying to wire a vacuum transducer outputting 0-10V to it. 0V = 0Torr 10V = 1024 Torr. I have the Vout (+) wired to IN 0 (+) and analog return to IN 0 (-).
While the sensor is sitting at atmosphere the voltage output is 7.4 (checked with a meter) before I wired it into the input module. However when I wire it in, the PLC reads 5.6V....which I also confirmed with a meter...giving me a reading of ~560Torr while the vessel is at atm.
Did I wire the input wrong? Is there something I have to configure in the plc?
Any help is greatly appreciated!
Thanks,
Denny
