I have a CompactLogix PLC that I am looking to integrate into a new application. I see that the unit operates by taking power from the +/- 24V DC terminals as well as the +/- FP terminals. I believe the FP terminals are used to power the output pins, etc?
My question is this: For simple testing purposes, is there anything wrong with using a standard lab workbench power supply with +/- 20V DC hooked directly into the screw terminals on the device? I also see that the back of the controller has a metal contact for a DIN rail. I don't have any such setup currently - could I just put in a small cut from a DIN rail I have on hand and connect that with alligator clips to the ground of the power supply I have on hand?
Apologies if these are stupid questions. I'm not much of an electronics guy and he won't be back until next week. Thanks for any guidance.
