Industry leaders team up to build hazardous area intrinsically safe subsystems

19 May 2009

Two of the hazardous area industry's leading suppliers have entered a technical collaboration to offer an intrinsically safe I/O interface for distributed control systems.

Invensys Process Systems (IPS) and Pepperl+Fuchs can now supply a seamlessly integrated interface solution for the I/A Series distributed control system.

With built-in barriers and field connections, the integrated modules are claimed to be the lowest-cost, smallest footprint and easiest-to-maintain solution for mounting I/O modules in hazardous locations. And this tight integration provides users with a transparent interface from which they can set up, configure and maintain intrinsic safety using standard I/A Series tools. The solution is
certified for Zone 1 and Zone 2 hazardous environments.

Betty Naylor-McDevitt, IPS Director of DCS Business explained:"Our clients are looking for proven, cost-effective ways to prevent disasters in hazardous environments, not simply contain them. Traditional explosion-proof cabinets are too costly to install and maintain, and our clients need reliable equipment that is easier to maintain and has a smaller footprint."

Seamless integration brings other benefits. Because the intrinsically safe modules are hot-swappable without a hot work permit, maintenance is easier and safer and with built-in redundancy in communication modules, power supplies and bus interfaces, availability is high.

The integrated solution is offered on Hart capable modules so I/A series system users can manage
intrinsically safe operation of any vendor's Hart field devices by utilising FDT compatibility available with IPS's Field Device Manager. Users will be able to set up, commission and maintain smart devices within a common engineering environment.
