S7-1200 1214C AC/DC/RLY Wiring diagram

Hi,

I am using the internal 24Vdc to supply all of my inputs and outputs.

When I shunt L+ with 1L and 2L, all of my outputs go high! Why?

Also All the negatives sides of the inputs and outputs are connected to M.The outputs and inputs devices all together do not exceed the 400mA limit.

Do I have to use a separate DC supply for the outputs?

Does anyone have a wiring diagram that uses the internal power supply for all of the outputs and inputs?

Thanks in advance,

Bruno
