Ex Control Units and Control Stations: Local Operator Interaction in Hazardous Areas

Explosion-Proof Control Units: Safe Interaction in Zone 1/2

Control Units and Control Stations from Pepperl+Fuchs are compact and reliable solutions specifically designed to ensure safe and efficient local control of equipment and process monitoring in hazardous areas (Zone 1, Zone 2, Zone 21, Zone 22). They serve as a key element of the Human-Machine Interface (HMI) directly in the field.

These devices are supplied as fully pre-assembled and certified stations, significantly simplifying installation and guaranteeing full compliance with ATEX and IECEx standards.

Design and Key Features

Control units combine various protection methods to ensure maximum safety:

• Enclosure Protection (Ex e): The housing is typically made of high-quality polyester or stainless steel using the Increased Safety (Ex e) method, which protects internal connections from sparking and overheating.

• Element Integration (Ex d): Control elements (pushbuttons, switches) can be either certified as separate components for Ex e or integrated via Flameproof Enclosures (Ex d) if they are sparking components.

• Modularity and Adaptability: Available in various sizes—from one or two pushbuttons to multi-section blocks. This allows for individual configuration of functionality: from a simple START/STOP button to a complex switching control panel.

Integrated Control Components

Control units can include:

• Pushbuttons and Switches: Latching or non-latching function buttons, key switches, mushroom-head Emergency Stop buttons.

• Indicators: Pilot lights that visually display the status of the process or equipment.

• Measuring Instruments: Ammeters, voltmeters, and other analog or digital meters.

• Cable Glands: Explosion-proof cable glands that maintain the integrity of the enclosure protection.

Customer Advantages

• Reliability: The enclosures are resistant to corrosion, chemicals, UV radiation, and moisture (high IP rating), guaranteeing a long service life.

• Time Savings: By supplying ready-made, certified solutions from CSC-Automation LLC, you significantly save time and resources on on-site design and installation.
