Hello to everyone and thanks for the help!!!!!

I have a PLC s7 1200 CPU 1212C AC/DC/RLY and I was trying to use the outputs to connect them to a fan of 24v 0.07Amps, first of all I probe the outputs whit a multimetter but I only get 0 volts reading, I connected the 1L to the positive terminal of the multimmeter and .0 digital output to the negative terminal of the multimetter. I hope someone can help me, I hope I didn't broke the PLC  but if it is that what happen i hope it has a solution, THANKS FOR THE HELP AGAIN!!!!!

I connected the 1L to the positive terminal of the multimmeter and .0 digital output to the negative terminal of the multimetter.

Hello Antonio776,

I do not use S7 1200 but it seems that your PLC have a relay outputs (RLY), why did you put on .0, the negative of your multimeter, should be the continuation of 1L, the output LED is lit? Look below the wiring diagram of your PLC
