The H-System consists of isolation barriers for signals from or into potentially explosive areas with galvanic isolation which are mounted on a termination board. The termination boards are mounted in the control cabinet on a 35 mm DIN rail. The signal loop between field and control side is closed by plugging in the module. The H-System is an efficient solution in medium-sized to large systems in combination with process control systems.

Intrinsic Safety Isolated Barriers from Pepperl+Fuchs - K-System Intrinsic safety barriers from Pepperl+Fuchs limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres.
