The Pilz PNOZ XV3.1 30/24–240VAC/DC 3N/O 1N/C 2N/O T, part number 774610, is a multifunctional safety relay designed to deliver high levels of safety, flexibility, and reliability in industrial applications. As part of the established PNOZ XV series, it offers a broad range of output options, wide operating voltage compatibility, and compliance with international safety standards, making it an excellent choice for safeguarding machinery and operators.

At the heart of the relay’s design is its versatile contact configuration. It features three normally open (N/O) safety contacts for immediate disconnection of hazardous energy sources, one normally closed (N/C) auxiliary contact for system feedback and monitoring, and two time-delayed N/O contacts that allow for controlled, staggered shutdown sequences. This combination provides enhanced flexibility in safety circuit design, particularly where machinery requires both rapid shutdown of certain functions and delayed stop of others, such as conveyor belts, motors, or drives that must decelerate safely.

The relay supports a wide supply voltage range of 24–240 V AC/DC, allowing it to be used across a broad variety of industrial installations without the need for multiple relay variants. This adaptability simplifies procurement, inventory management, and system integration, particularly for companies operating globally or across diverse production environments.

The switching capacity of the PNOZ XV3.1 is another key strength. Its safety contacts are rated for up to 240 V AC / 8 A and 24 V DC / 8 A, making it capable of handling robust loads across both AC and DC circuits. This ensures reliable operation in a wide array of applications, from controlling actuators and drives to disconnecting power to critical machine components.

Built to comply with EN 60947-4-1 utilisation categories, the relay ensures consistent performance, durability, and adherence to recognised safety requirements. Compliance with this standard provides reassurance that the relay has been tested and certified for use in demanding industrial safety applications, making it a trusted solution for system integrators and manufacturers alike.

Applications for the PNOZ XV3.1 include emergency stop monitoring, safety gate supervision, and the integration of light curtains or two-hand control systems. Its time-delayed contacts are especially beneficial in systems where staged shutdown enhances both safety and mechanical longevity. By providing immediate and delayed outputs in one device, it reduces the need for multiple relays, simplifying wiring and system design.

With its robust electromechanical construction, the relay guarantees long service life and dependable performance even under continuous operation. Its compact form factor and straightforward wiring make it easy to install, maintain, and integrate into existing systems.

In summary, the Pilz PNOZ XV3.1 30/24–240VAC/DC 3N/O 1N/C 2N/O T (774610) is a flexible, powerful, and standards-compliant safety relay. Offering a wide voltage range, strong switching capacity, and a highly adaptable contact configuration, it provides an effective solution for protecting machinery and personnel across a wide variety of industrial applications.
