| Zener Barrier ZbC2+ | COMET SYSTEM, s.r.o. | The Zener barrier ZbC2+ is a certified intrinsically safe interface. It is used to connect a certified intrinsically safe device located in a potentially explosive atmosphere (Hazardous area) to a non-certified device that is in a safe area. The Zener barrier prevents the transfer of unacceptably high energy from the safe area into the hazardous area. The ZbC2+ Zener barrier contains two identical diode return barriers in a common housing and it is designed for DIN rail mounting in a safe area. | More | |
