I am trying to use existing spare c

[Katy1163]

I am trying to use existing spare circuitry on a board to supply the controlling inputs to an SSR. It seems what I have most readily available are a comparator circuit and some optoisolators. The relay is the Crydom CMX60D10. Anyone have any suggestions?

Thanks!

Since you provide no other info it's not possible to say.

One of your outputs needs to be able to supply 3V to 5V and 15 or more mA that you can control.

But, what's going to drive the comparator or optoisolator? Seems like either could be configured to drive the 3-10V control input

Note that the Crydom datasheet shows an internal optoisolator:

and the p-channel MOSFET is completely powered from the load side.
