Goodday

To answer in short NO it wont work with DC Volts on the Primary side.

The switching device in the SSR are called TRIAC/SCR that are an AC switch it needs an Zero Crossing to turn the flow of current off

else it stays in an ON state when you trigger the input with DC volts normally 3-30Vdc
