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.
? H-System interface modules
H-System interface modules easily snap on to the termination boards with plug & lock installation—no wires, no tools. The modules secure the galvanic isolation between the intrinsically safe field signals and the secure non-Ex-side.
H-System interface modules feature high channel density, reduced space requirements, single loop integrity and simple commissioning. Two module groups are available.
? HiD-Interface modules
The 18 mm (width) HID-modules feature high packing density, low power dissipation, and SIL 2/3 ratings. Up to 64 channels can be installed on a 16-position termination board.
? HiC-Interface modules
Only 12.5 mm wide, single-channelled HiC-interface modules feature single-loop integrity, SIL 2/3 ratings, and reduced cabinet space requirements by as much as 33%. Their low power dissipation keeps the cabinet cooler and increases the life of the modules. Even though more channels can be packed into a cabinet, less power is turned into heat.
