Caution: Explosive!
Universal genius – even under adverse conditions

Flexibility has a name:

More than 500 I/O modules, 60 controllers and 40 fieldbus couplers – that is the WAGO-I/O-SYSTEM 750. No automation system is so flexible, offers so many variants and can be adapted individually to the project – despite ambient conditions: The WAGO-I/O-SYSTEM has international approvals for the process and marina industry, e.g., ATEX, IECEx and UL ANSI/ISA, for worldwide use even in stricter operating conditions in potentially hazardous environments (dust, gas and mining). The WAGO-I/O-SYSTEM has reliably served in oil rigs and coal mines for years.

Customer Applications

Modular and Standardized Field Level Integration – from Zone 1

Filling above-level, sub-level or below bunghole – this is what you hear when experts talk about drum filling technology. Feige FILLING GmbH – headquartered in Bad Oldesloe, Germany – is an international leader of filling machines for liquid and pasty products. The manufacturer, located in the Northern German state of Schleswig-Holstein, develops Ex-proof solutions for ATEX Category 1 because their filling machines mainly operate in hazardous areas. To meet these requirements, Feige FILLING relies on the universal WAGO-I/O-SYSTEM 750 at the I/O level.

Reference Report

Das WAGO-I/O-SYSTEM verfügt über die gängigen Schiffbauzulassungen für den Offshore-Einsatz, wie DNV*GL oder ABS, und behauptet sich ebenso in explosionsgefährdeten Bereichen (Staub, Gas und Bergbau). Von der Bohrinsel bis zum Kohlenflöz ist das WAGO-I/O-SYSTEM seit Jahren zuverlässig im Einsatz.

Passt! Einfach! Da das System für den Einsatz im explosionsgefährdeten Bereich zugelassen ist lassen sich die Ex-i-Module mit den Standardmodulen ganz einfach kombinieren. Das sorgt für viel Flexibilität bei der Gestaltung des Automatisierungskonzept.

Keep up with the flow

New Level of Automation for Electrical Trace Heating Systems in Pipelines

The Russian company OOO SSTEnergomontazh intended to substantially increase the degree of automation of its electrical trace heating systems for pipelines to offer customer-tailored solutions and keep pace with the trend toward greater automation in the oil and gas industry. Using explosion-proof components from WAGO, the company succeeded in doing this easily and economically.

Explosion Protection for Wastewater Plants

Several specialized and general regulations complicate the construction and operation of a technical wastewater plant and make it anything but trivial. Planners and operators can significantly lower their expenditures by selecting an intelligent control system that supports standard and special applications equally.
