Hey guys I am looking at this wiring diagram for a Johnson actuator, and its not making a great deal of sense to me. Its the common that's confusing me, So does the -negative for the control signal and the -negative for the 24VAC power share the same -negative? Or is the Feedback the Negative for the control signal? Not too knowledgeable on these things and don't want to fry the actuator, I know a few people have used these previously just looking for some insight. The setup I am using has the following pieces , the Power supply is a 24vac 3.2va transformer, PID is a C700 powered by 240v. I am guessing that the following is correct but I am just as likely to be wrong!
FB = mA -negative VDC/mA = mA +positive +24 = 24VAC +Positive COM = 24VAC -Negative
