Isolated barriers for motherboard termination

July 2011 IS & Ex

For process application requirements the H-System from Pepperl + Fuchs secures galvanic isolation between intrinsically safe field signals and the secure safe side signals of the control system. The interface technology of the H-System offers an ideal PC board termination solution, allowing users to customise the termination board, I/O specification and system connectors.

The H-System is available in two ranges: HIC for single loop integrity and the smallest footprint and HID for the highest channel density and functionality. The H-System has worldwide certification and is SIL2 as standard with SIL3 available.

The solution is designed to save cost and space with connection to the control system via connectors for reduced planning and start-up time. Simple maintenance due to pre-wired boards and snap on interface modules, combined with minimum space requirements and power dissipation in the cabinet, make the H-System a cost optimised solution.

The digital communication from the field devices to the asset management software can easily be implemented by the HART communication board. Collective errors from the termination boards are signalled via the fault indication relay outputs.
