Re: [CAD_CAM_EDM_DRO] VOLTAGE APPLIED TO PLC INPUTS

Be careful.
Not all PLC inputs are created equal.
To verify what type of input your PLC is, check the label near the input. If
there is none then find the manufactures name and model number and go to
their website and find the spec's or manual of that model.

Some are 24 volts DC , 5 VDC, or even 120 VAC. So be careful.

Hopes this helps
