The Pilz PNOZ XV3.1 3/24VDC 3N/O 1N/C 2N/O T, part number 774532, is a high-performance safety relay engineered to provide flexible and reliable protection for both personnel and machinery. As part of Pilz’s established PNOZ range of safety relays, it combines advanced contact configuration with efficient operation and full compliance to international standards, making it an essential component in modern safety systems.

Operating at 24 V DC supply voltage and consuming only 4.5 W, the relay is optimised for energy efficiency without compromising performance. Its compact, robust design ensures easy integration into control panels, providing both reliability and space-saving installation for machine builders and operators.

A key advantage of the PNOZ XV3.1 is its versatile contact configuration. With three normally open (N/O) contacts, one normally closed (N/C) contact, and two additional normally open timed (N/O T) contacts, it offers extensive flexibility for a wide variety of safety applications. The immediate safety outputs provide reliable disconnection of hazardous energy sources, while the timed contacts can be used for staggered shutdown or controlled stop sequences—particularly valuable in systems where controlled deceleration of drives, conveyors, or motors is required.

The inclusion of two independent input channels allows for dual-channel monitoring, ensuring cross-checking of safety signals. This redundancy enhances fault detection capabilities, making the device suitable for applications where higher safety integrity levels are required. Whether monitoring emergency stop buttons, guard door switches, or light curtains, the PNOZ XV3.1 guarantees that unsafe conditions are immediately identified and acted upon.

Engineered with compliance to EN 60947-4-1 utilisation categories, the relay delivers reliable switching performance even under demanding operational conditions. This ensures durability, consistent performance, and adherence to regulatory requirements across diverse industrial sectors, including manufacturing, material handling, robotics, and processing.

In addition to safety and reliability, the PNOZ XV3.1 is designed for ease of integration and maintenance. Its fixed wiring approach reduces complexity during installation, while its robust electromechanical components guarantee long service life and low downtime. This contributes to lower total cost of ownership while maximising operational uptime—key priorities for competitive industrial environments.

Applications for this safety relay span across industries where hazardous machine movements must be controlled, hazardous energy must be safely disconnected, and safe stop sequences are critical. Its combination of immediate and timed safety contacts makes it particularly valuable for machines with dynamic stopping requirements.

In summary, the Pilz PNOZ XV3.1 3/24VDC 3N/O 1N/C 2N/O T (774532) is a versatile, standards-compliant safety relay that blends energy efficiency, advanced contact functionality, and robust design. With its dual input channels, flexible outputs, and compliance to EN standards, it offers machine builders and operators a powerful, reliable solution for safeguarding machinery and personnel.
