Trying to determine the best way to have a pc controllable (via usb, serial, or ethernet) 3 phase power. My setup now uses a watlow 97 limit controller that turn on and off a squared-D 3phase 3pole 30A contactor DPA33 V09.
I think choose a solid state relay and a relay control module is the appropriate route.
Any advice on a 3phase 30A 230V SSR and control modules? THanks.
