I'm guessing the PC socket will have the same ratings as the hot shoe on that camera. But without telling us which camera, no one will have any way of knowing anything.
And sure, you can use a radio trigger. I do that all of the time. You just need to make sure the radio trigger can handle the trigger voltage you intend to subject it to and make sure you have all of the proper adapter cables. And what voltages it can handle with which cables you need will depend on which model of radio trigger you use. I specifically chose Phottix for my radio triggers because their receivers can handle high voltages, and they're not crazy expensive.
