The Benefits of
THE BARRIER
at a Glance:
■
■
An isolated barrier for AI, AO, DI, and DO
■
■
Automatically adjusts to signal types
■
■

Keep it Simple! This motto puts THE BARRIER – a smart universal
barrier – into practice perfectly. It’s the first isolated barrier to replace several traditional
modules with a single multifunctional I/O module, combining standardization with flexibility.
It saves space, and simplifies planning, engineering, configuration, and maintenance.
self-adjusting I/O module is optimally designed for modern, universal I/O
cards from leading control system manufacturers and covers more
that 90 percent of all applications,” explains Andreas Grimsehl, Product
Marketing Manager for Interface Technology at Pepperl+Fuchs.”
Because you no longer have to worry about different signal require-
ments, THE BARRIER significantly reduces planning and engineering
effort. “Since the user only has to use a single barrier, the cross-connect
level with the switch cabinet is not required, meaning that the amount
of required wiring and storage costs are greatly reduced. Furthermore,
configuration and maintenance in the field are considerably simpler,”
states Grimsehl. “In this way, THE BARRIER intelligently optimizes flex-
ibility and standardization – in short, this means more possibilities with
fewer variants.”

same language – or if an interpreter who understands both languages
facilitates their communication. The situation is similar in the process
industry: For field devices to be able to relay their message to the
control system, all components involved in signal transmission must
be capable of understanding the same language, or in this case, the
same signal type.
For process technology plants, there is one more requirement: explosion
protection. For tried-and-tested interface technology, isolated barriers
are often used for intrinsically safe protection. These isolated barriers
limit the power that can enter into the hazardous area.
Previously, if different signal types were used, different barriers were
required. But this is not the case with the new HiC2441 universal
barrier, which is a member of the tried-and-tested H-System from
Pepperl+Fuchs. THE BARRIER automatically adapts to the required
signal type and the universal input cards of control systems. “The
