Are triggering voltages standardized?
Good question. I don't think that there are absolute standards,but there are common ranges. IIRC it is 3v to 12v but I would need to double check. I think Paramount and Wein (probably others too) sold protected cords that limited the voltage to the sync contact to 6v, so that is probably the target range. (that is synced to a cord and not the hot shoe) I think most radio trigger systems are 12v or less. I'm working from memory here, so best advice is to double check if you have a mismatched set up. You do not want to put that old Vivitar 283 with it's 300v trigger on your new DSLR. I'll have to dig around later and see what info is out there.
