Vivitar 285 Zoom Thyristor - will it work?

So I found one of these when I was going through the stuff my grandpa had given me and i set it up and put it on my film camera. It works fine on that but I was wondering if it would work on my Canon Rebel XS. Don't want it to mess it up. It's not the HV version. Thanks!

NO Do NOT even attach it to your Canon digital camera, the old ones had much higher trigger voltages that will fry the circuits in your digital camera in a heartbeat, Those flashes were made for film cameras w/o all the electronic circuitry in our digital cameras.

Is my old flash unit safe for my new camera?

With that unit I would not rely on someone else's table. I would get a voltage tester and test it myself.
