Contactron pro is a hybrid motor starter that simplifies wiring and safety integration. It has a T-bus backplane system that rapidly distributes 24-V power, bridges the e-stop enable signal and adds auxiliary contact modules. These modules allow motor state feedback and implementation of self-sealing motor circuits. When used with the PSR-MC38 safety relay, the motor can permit a SIL 3/PLe group of emergency shutdowns via one interface. The modules incorporate Phoenix Contact’s hybrid technology, which offers three-phase motor switching up to 5 hp. It has a service life of up to 30 million switching cycles.
