Re: VFD interface to other equipment.
The SSR shown is an AC version, you need a DC version, also that is ~10amp rated, way overkill, you can get the older style smaller Opto22 modules cheap that are used typically in this application.
They come in 5vdc or 24vdc input power
And that is shown sourcing configuration, you need to sink the VFD input. Just as is done with a relay (sink) contact
