Hello, Just a quick question. I'm using C0-16TD2 modules for outputs (transistor outputs). Should same power supply that is used for powering CPU and inputs be used to power outputs, or I can use other power supply? I know this isn't a problem with inputs because of optical isolation, but I'm not so sure about outputs.

The same power supply can be used for the CPU, inputs, and outputs.
There will most likely be more noise on the DC line when this is done, especially if the outputs are inductive loads like relay coils.
A separate power supply can be used on the outputs when this is a problem.

That's what I needed. Thanks.
