The direct way is always the better way: The new Segment Protector – zone 2 communication made easy

Simplicity leads to faster, better and safer solutions. That's why simplicity is the core idea behind the innovative solutions for FOUNDATION Fieldbus H1 and Profibus PA from Pepperl+Fuchs. One typical example is the new series R2 Segment Protector. It allows fast connection of field devices with all safety characteristics, such as short-circuit protection and the High-Power Trunk for explosion hazardous applications. It is a smart idea, designed for fast installation, easy wiring and guaranteed reliability.

The new series R2 Segment Protector by Pepperl+Fuchs is an intelligent wiring block designed to add simplicity, speed and safety to the installation of any fieldbus infrastructure. Up to twelve field devices can be connected to the fieldbus via its own spur connection with built-in short-circuit protection. Using the High-Power Trunk concept guarantees Zone 2/Div. 2 explosion protection. In this configuration, the main line is fed with up to 500 mA, while the energy supplied to each individual spur is limited. Built-in short-circuit protection takes care of the needed reliability during operation. Live working on the field instrument does not require any hot work permit, since the trunk is free from feedback and remains fully in operation.

The R2 Segment Protector: Short circuit protection included.
And your choice of spur connections for your fieldbus distribution 4 to 12 spurs.

Fast installation

The new Segment Protector combines compact dimensions with easy operation and is designed for quick installation into any cabinet. A variety of pre-configured housing models offers a suitable solution for just about any situation. Easy-to-use clamp fasteners securely attach the unit to the DIN rail. All plugs feature retaining screws for reliable connection.

Manual intervention in the field

Connection to the trunk is done via a T-connector. This allows easy trouble shooting or replacement of the Segment Protector without disturbing the operation of the overall system. The fieldbus terminator finds its well-defined and easily visible position at the T-connector where it can be easily verified. In this way, faulty termination is avoided during the installation process. Specific test points are included to efficiently hook up diagnostic tools. Measurements during installation and trouble shooting can be performed without having to interfere with the wiring.

Many small details such as the T-Connector allows manual intervention in the field and there is always a secure place for the one fieldbus terminator.

Easy wiring and guaranteed reliability

The new Segment Protector features innovative and well thought-out solutions which result in reduced wiring and considerably lower hardware and operating costs of the fieldbus infrastructure. The Segment Protector is a vital component to add reliability to the fieldbus. It leads to a continuously superior signal quality, thereby improving the overall availability of the system. Only the fieldbus guarantees unlimited flow of information from the process control system all the way to the field device. This allows comprehensive remote configuration and offers the technical basis for effective asset management.

The new series R2 Segment Protector is another example of intelligent fieldbus solutions from Pepperl+Fuchs.
