Isolated Barriers (H-System)

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.

• ​​No expensive and manual individual wiring thanks to fixed wiring
• Fast and safe connection to the process control system
• Less effort for planning and wiring, installation and commissioning, documentation
• High availability thanks to diagnostic function and fault monitoring in modules and terminati-on boards

• Termination Boards

Tested and cabinet optimized solutions are obtainable for many control systems. Versions with universal design are available, either with terminals for selectable contacting, or with sub-D-connectors for adaption to control system specific cables.

• Modules

The H-System module portfolio includes with the 12 mm wide HiC versions the narrowest modules. The 18 mm wide HiD modules offer the highest density with regard to termination board based systems.
