The different types of SSR's are rated with an input control voltage which can be logic 5v only or 24vdc or 3-36vdc, this is the control voltage used to switch the SSR, the output can be various types and voltages, i.e. the output can cover 110vac to 240vac or DC types can cover 65vdc for example. The output should not vary as long as you have the correct input switching voltage.
