It is in applications such as these that Pepperl+Fuchs is putting the universal barrier to successful use: The self-adjusting I/O module for AI, AO, and DO signal types covers the vast majority of all applications that occur in processing systems in a wide range of industries. For the signal type DI, the module is optimized for universal I/O cards such as the Experion Series C from Honeywell — with a Namur current level instead of voltage level.

In addition, the use of a switch amplifier makes the universal isolated module compatible with other, comparable input cards. The ability to record all signals using just one version of an intrinsically safe barrier significantly reduces the complexity of planning and engineering work. What’s more, the universal barrier adjusts itself, meaning it does not need to be configured.

During commissioning, it is sufficient to configure the universal input card of a DCS from the control room in line with the functionality required from the individual channels.

Parameterization work in the field is no longer required, a fact that also applies to the marshalling panel. In the case of conventional isolated barriers, field signals accumulate in the marshalling panel, where they are subsequently put into order for each specific signal and for each input card.

With the “soft marshalling” function that has become available, the IO channel can now be defined at the click of a mouse button. This significantly reduces the amount of time required for the manufacturer to perform the factory acceptance test. A marshalling switch cabinet is therefore not necessary.
