No output voltage

Recommended Posts



I have a very basic question, I am not sure if I don't know something or the PLC is broken. My PLC is the M90-T1 model. When can I measure the 24V on the output side? I have measured 0V on the main output... I also installed a sample program which would blinks a lamp on output0... that doesn't work.

Hello Senszey,

Please have a look at the attached image.

Basically, it describes the digital output configuration for the PLC.

In general, digital outputs are not getting their voltage supply from the PLC's power input, but from another circuit. Hence, to energize your outputs you will need to add another 24V source which will be wired as stated in the attached image.
