Interface module
No wires, no tools allows the H-System interface module a plug & lock installation that snaps right on to the termination board. Galvanic isolation is secured by the modules between safe field signals and the secure non-EX-side. These modules of the H-System feature simple commissioning, space requirements are reduced, single loop integrity, and a high channel density. There are two groups of modules available. The HiD-Interface modules are 18 mm wide and they feature lower power dissipations, high packing density, and ratings of SIL 2/3. For a 16 position termination board up to 64 channels can be installed. The HiC-Interface modules are only 12.5 mm wide. These modules are single channeled with a single loop integrity and a 33% reduced cabinet space requirement with a rating of SIL 2/3. The cabinet stays cooler with the lower powered dissipation thus increasing modules lifespans.
