The Pilz PNOZ XV3.3P 30/24VDC 3N/O 2N/O T (777511) is a high-quality safety relay designed to safeguard personnel and machinery in a wide variety of industrial applications. Part of the widely recognised PNOZ series, this relay embodies Pilz’s reputation for reliability, flexibility, and compliance with international safety standards.

Operating at 24 V DC, the XV3.3P integrates seamlessly into modern automation infrastructures, providing stable and energy-efficient operation. Its power consumption of 4.5 W is optimised to deliver consistent performance while maintaining energy efficiency, a key factor in today’s cost-conscious industrial environments.

The relay’s contact configuration is one of its most versatile features. With three normally open (N/O) safety contacts and two N/O auxiliary contacts, it allows for flexible system design. The N/O safety contacts provide reliable disconnection of hazardous machine functions, while the auxiliary outputs can be used for signalling, diagnostics, or controlling non-safety-related functions. This reduces the need for additional relays, streamlining wiring and panel design.

The two independent input channels make the PNOZ XV3.3P suitable for monitoring a wide range of safety devices, including emergency stop buttons, safety gates, pressure-sensitive mats, and light curtains. This dual-channel configuration ensures that faults are detected quickly, enabling immediate safe shutdown of hazardous movements to protect operators and equipment.

The relay is certified to the EN 60947-4-1 utilisation category AC/DC-1, guaranteeing robust switching capabilities even in demanding applications. This compliance demonstrates that the relay has been rigorously tested to handle industrial load conditions, ensuring dependable performance over a long service life.

Typical application areas for the PNOZ XV3.3P include manufacturing lines, robotics, packaging machinery, presses, and conveyor systems. In these environments, the ability to reliably halt machine operations in response to safety inputs is essential for preventing accidents and ensuring compliance with machinery safety regulations such as EN ISO 13849-1 and IEC 62061.

As part of the Pilz PNOZ portfolio, this relay integrates easily with other Pilz safety products, supporting modular and scalable safety system designs. This flexibility makes it a valuable choice for both small standalone machines and large, interconnected automation networks.

In summary, the Pilz PNOZ XV3.3P 30/24VDC 3N/O 2N/O T (777511) is a compact and robust safety relay offering dual-channel inputs, flexible contact configurations, 24 V DC operation, and certified compliance with EN 60947-4-1. Its versatility and proven reliability make it an indispensable solution for ensuring operator safety and protecting machinery across a broad range of industries.
