Festo Tab series Pneumatic Logic Controller with AND function

This pneumatic logic controller is a Compact pneumatic AND logic device designed for control tasks in potentially explosive atmospheres. It provides pneumatic-only logic to combine input signals and produce a controlled output suitable for use in hazardous locations defined under ATEX. The unit aligns with industry expectations for pneumatic logic modules used in process and automation environments.

• Certified for use in Zone 1 hazardous atmospheres enabling safe operation
• Suitable for Zone 2 environments supporting broader installation flexibility
• Approved for Zone 21 and Zone 22 dust-explosion areas allowing mixed-hazard deployment
• Implements an AND logic function to combine multiple pneumatic inputs
• Complies with VDMA24364 Zone III for standardised pneumatic control behaviour
• Manufacturer-grade construction delivering consistent pneumatic switching performance

• Suitable for pneumatic interlock control in hazardous process plants
• Ideal for fail-safe actuator sequencing in explosive atmospheres
• Used with pneumatic valve systems for logic-based control in zone-rated areas
• Can be used for safety-related pneumatic control in chemical plants

It is suitable for gas Zones 1 and 2 and dust Zones 21 and 22 under ATEX, enabling use where explosive mixtures may be present intermittently or continuously.

It implements an AND logic function, requiring all specified pneumatic inputs to be present before energising the output, which simplifies interlock and sequencing arrangements.

It conforms to VDMA24364 Zone III, a recognised standard for pneumatic control modules in zone-rated installations, facilitating specification within industrial control schemes.
