He was talking about the output, so I assume we're talking about the voltage that's being switched, not the input.

Are we talking about AC on the contacts?

Coil will only work with what it’s specified for (AC or DC).

Contacts will be fine with AC if they have a DC rating.   The inverse isn’t necessarily true.

But the reverse is generally not a problem. AC RMS  current is much less demanding than continuous DC current.

I have had AC coil relays get stuck closed with putting DC on them.

Yes, some do.  Some will get magnitized if they are AC relays and you use DC
on them.

The Specsheet for the 4 channel relay output unit says 1A@24VDC.  I want
to control some HVAC Dampers that are running at 24VAC.  The Relay
doesn't care if it's VAC or VDC right?
