The Benefits of

THE BARRIER

at a Glance:

■

An isolated barrier for AI, AO, DI, and DO

■

Automatically adjusts to signal types

■

Fast, easy commissioning without any

adjustments to hardware or software

■

Part of the H-System; power supply via

termination board

■

Cross-connect level can be omitted;

less wiring required and no need for

a marshalling cabinet

■

Simplified maintenance and storage

thanks to a reduced number of parts

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.”

Two people can understand each other only if they communicate in the

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
