H-System – Isolated Barriers and Termination Boards for HIMA
Product Specifications

System Components
2.2.1
Isolated Barriers
H-System isolated barriers are available in two different housing widths
depending on the function and application:
• HiC devices with a width of 12.5 mm
• HiD devices with a width of 18 mm
Both versions cover all functions and the interoperability of the H-System.
The pin assignment and terminal designations are consistent for all termination
boards. Each H-System isolated barrier can therefore be mounted in each
termination board slot.
• HiC isolated barriers on HiC termination boards
• HiD isolated barriers on HiD termination boards
The board can be coded together with the isolated barriers. This prevents the
isolated barriers being mixed up on the termination board. The safety-relevant
data for the connected field devices is backed up.
