INTRINSIC SAFETY BARRIER

Intrinsic Safety BarriersIntrinsic safety barriers from Pepperl+Fuchs limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres. This simplifies maintenance and repair of Ex i circuits.

Pepperl+Fuchs offers a variety of intrinsic safety barriers for different requirements. Select between isolated barriers and Zener barriers that ensure safe signal transmission in hazardous areas.

Isolated Barriers
In addition to their explosion protection function, isolated barriers offer galvanic isolation to protect measurement and control circuits from signal distortion and dangerous surges. These interface modules also convert, standardize, and split measurement and control signals.
Zener Barriers
Zener barriers prevent the transmission of excessively high energy levels from the non-explosion hazardous area to the hazardous area. These interface modules are the right choice when galvanic isolation is not needed or otherwise provided.
Intrinsic safety barriers are the core of Pepperl+Fuchs' product portfolio. We offer the widest selection of products for protection of electrical signals located in hazardous areas. These intrinsic safety modules combine the energy limiting features of a zener barrier with galvanic isolation. Pepperl+Fuchs offers systems for different applications and mountings.


K-System
Our most popular intrinsic safety isolated barriers are the flexible DIN rail mounted K-System modules. The K-System intrinsic safety barriers connect easily with our Power Rail assembled in the DIN rail. The use of the Power Rail reduces the wiring by energizing the modules mounted on the DIN rail.

H-System
The intrinsic safety isolated barriers of the H-System are mounted on termination boards. This innovative product is ideal for applications requiring tight DCS or system integration.

ZENER BARRIERS

Zener barriers are a cost-eff ective solution for providing an intrinsically safe interface with field devices located in the hazardous area. As part of the intrinsic safety barrier family, Pepperl+Fuchs off ers two distinct zener barrier systems. The Z-System barriers are 12.5 mm wide and mount and ground directly to standard 35 mm DIN rail, while the SB-System barriers are the only termination board solution with pluggable modules available on the market. In addition to this wide product portfolio of housing and connection styles, we off er accessories for each application.

    MTL7700 range
    DIN-rail mounting safety barriers

    •     Removable terminals
    •     Bussed power feed to other modules
    •     Relay and solid state switch modules
    •     Dual channel variants – 6.3mm per channel
    •     Proximity detector inputs
    •     Electronic fusing
    •     Direct replacement for MTL700 range    barriers
    •     Compatible terminal numbering and safety descriptions

    The MTL7700 range follows closely in the footsteps of the MTL700, but as a DIN rail mounting barrier, providing quick and easy installation without the need for special hardware

    Removable terminals are used for ease of installation, maintenance and for providing a loop disconnect by simply unplugging the terminals from the side of the module. 

    MTL7700 barriers clamp simply and securely onto standard T-section DIN rail, simultaneously making a reliable IS earth connection.

    For applications where field power is required for switch inputs or 2-wire transmitters, the MTL7700 range provides a bussed power feed facility. When used in conjunction with the MTL7798 power feed module the user has a fully protected, electronically fused supply to many barriers with no additional wiring required.

    MTL7700 active modules are protected with an electronic fuse for the majority of applications.

    Shunt-Diode Safety Barriers and Galvanic Isolators  a Critical Comparison By L C Towle BSc CEng MIMechE MIEE MInstMC Technology Director The MTL Instruments Group plc Introduction The discussion on the relative merits of galvanic isolators and shunt diode safety barriers has been carried on for many years. The majority of other articles on this subject have aimed to prove the superiority of one technique over the other. This paper brings together the illustrations which have accumulated over a considerable time in response to various questions raised at presentations. It attempts to make balanced arguments so that the reader can decide the most suitable technique for a particular application. It ends with a score sheet which might be found useful if a decision is not completely self revealing. The paper has evolved over a considerable time, however it is unlikely that it covers all aspects and will inevitably need to be revised as techniques develop. If you have any comments on the contents or omissions within this document the author would like to receive them. In this way the document will become more comprehensive and more valuable.
