Allen-Bradley 1756 wiring

[serpesus]

Hi there,

Maybe a bit stupid question, but I have a ControlLogix5573S with IB32 DI module installed in 1756 chassis and I am a little confused about the wiring - let"s say I want to connect a simple switch to the input. So I wire up the DC power source to the switch, switch to the input, but I cant find where to ground the power source. My question is basically where to put the ground.

Thanks

Card GNDs to power supply common. Just to confirm you are using 24vDC correct?

Okay so now, I feel really stupid, because I tried to find any sort of pin layout for the module, but I didnt have any luck doing so. Right until now

My module didnt had any documentation about pins, when I received it, so I didnt know where the GND were located.

Still, thanks for help
