Great video and on point. During my time in electrical industrial maintenance the most common PLC module we would find failed were both SLC relay output cards as well as Compactlogix. The relay outputs would typically be failed in the closed position especially on power open, power closed valves. Something to keep in mind is that 120V Triac outputs commonly leak current in the off state and can mimic almost full line voltage to a voltmeter with the output in the off state without a load attached.

Is it possible to attach the manual to see it clearly. It will be more clear for me if I can see the wiring diagram.

Good job sir, exactly how I would have done it. I’ve actually ran into this out in the field several times, had 2 output cards with bad relay terminals not putting out voltage. You don’t see it much but I always like to add circuit breakers on my outputs when I build and wire control panels, a lot of times the output in the field could possibly take out the output it’s attached to. Good video!

thank you so much im between a tech 2 and tech 3 at my profession and had a little hard time understanding this. Now if i may adk a question so in this case if i dont have a laptop available, how do i force the button to stay on while i check?

@KletteTech Ай бұрын

I do not believe you can. You would have to know the logic that is in the program and activate the inputs

What if it was wired with wetted voltage? If the output is sinking, the power goes to the bulb, and then to the output contact.

I had 6 outputs from a plc, these are nozzles that were opening accordingly as programmed. However, after some times the began to operate inappropriately. Instead of opening and closing sequencially as programmed, they began to open and close in a wild manner, what could be the cause, any idea on what i should do?

Is it common to wire 120V load through the PLC outputs or better to wire a low voltage relay first? Let's say I have an air solenoid valve (120V).

@scoutsx_d4441 5 ай бұрын

solenoid valves are inductive loads which will generate back emf. Typically the solenoids come with built in diode protection, but it is always good to put an interposing relay to separate the output from the load. Cheap solution and much safer.

Thanks, that's what I was thinking.

@KletteTech 5 ай бұрын

Agreed. For simple pilot lights and other low current devices you can wire through the PLC

@garrettsmith6679 2 ай бұрын

So you activated the output manually and it’s not coming on so you know it’s not the trigger signal or input to activate that output. But which input is suppose to active that output?

@KletteTech 2 ай бұрын

That is determined by the logic that is programmed into RSLogix 500

@garrettsmith6679 2 ай бұрын

@@KletteTech so the plc receives data from whatever that light is referencing to? Also how do the inputs work, do they correlate directly with a certain output or do you program any input to whatever output you want? Thanks for the responses

@daveb9370 Ай бұрын

@@garrettsmith6679you can program any input to any output. Another quick test is to use a jumper wire from the correct voltage source, in this case 120 vac, from the input to the output terminal, and if the device works, you know the output is bad.

Report back to the bosses lol that had me laughing my ass off! Just move the output to another open spot or just add another 120v output card. PLCs lose Inputs and output all the time. Don't make a bigger problem than it really needs to be. If you know the bulb is good, go straight to the output and check it there.
