I was wondering if anyone can tell by the datasheet if this SSR is triggered at the zero crossing or "random firing" as it doesn't seem to indicate that information anywhere. The reason I wonder is because I'm using it to control a larger non-SSR relay which has a 24VAC coil, and that coil being considered an "inductive" load, I'm concerned it may not always "turn off" as expected. Or, maybe because the coil on that regular relay draws such little current, if it even matters.
Thanks,
John
It would be considered random turn on. In reality, its instant turn on if your input is dc, random if ac driven.
Your concerns about turn off do not apply since this relay is not triac or scr based, it is dual mosfets which do not require the load to go through zero current to turn off.
Thanks avr_fred, especially for such a quick response!
The load is AC, in which I've experienced problems with turn-off of inductive loads such as motors with zero-crossing SSRs, before when I understood nothing about it. But did not even consider the use of the dual mosfets making that into a non-concern - great to know. 
Hi,
You can use a zero crossing SSR for your application. Like the Mouser part number 653-G3MC-202P-DC5 . You need to make sure it meet your load.
Zero crossing for this application, being inductive load of the coil for the larger relay it's serving?
I've used the non-zero crossing G3MC-202PL-xx in similar situation before, considering the G3MC-202P-xx is for resistive load. In this application, because of a small load, I can make use of a smaller form factor, thus the one I chose. I suppose for larger application, but still low wattage either one zero or non-zero crossing would work okay though? I've used the non zero crossing G3MC-202PL-xx for switching the 24vac solenoid controlling a rainbird sprinkler valve.
