H-System – Isolated Barriers and Termination Boards
Product Specifications
2.2
Isolated Barriers
H-System isolated barriers 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.
The termination 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.
