The Pilz PNOZ 15 24VDC 3N/O 1N/O 1N/C (Part No. 774050) is a compact and versatile safety relay designed to provide reliable monitoring of emergency stop functions, safety gates, and other protective devices in industrial automation environments. Belonging to the trusted Pilz PNOZ series, this relay offers proven safety technology for safeguarding both operators and machinery while maintaining smooth operational flow.

Operating on a 24 VDC supply, the PNOZ 15 consumes only 3.5 W, making it highly efficient for continuous use in demanding industrial settings. Its low energy requirement makes it ideal for businesses seeking to optimise power usage without compromising on safety performance.

The relay is equipped with two safety inputs, enabling dual-channel monitoring for higher safety integrity and redundancy. This ensures that even if one input fails, the system continues to provide reliable protection. The outputs are designed for flexibility, with three normally open (N/O) contacts, one normally open (delayed), and one normally closed (N/C) contact, plus one semiconductor output. This combination allows engineers to integrate the relay into a wide variety of safety architectures, supporting direct control of actuators, contactors, or signal outputs. The delayed contact option provides controlled shutdown sequences, ensuring safe power-down of equipment.

Engineered to meet international safety standards, the PNOZ 15 is suitable for use in systems requiring high safety categories, including up to Category 4 / Performance Level e (EN ISO 13849-1) or SIL-level compliance under IEC 62061. This makes it an ideal choice for industries where regulatory compliance is essential, such as automotive, packaging, material handling, and process manufacturing.

In addition to robust safety performance, the relay is designed for ease of integration and long-term reliability. Its straightforward wiring and compact design allow installation in control cabinets with limited space, while its durable construction ensures long service life, even under continuous duty and heavy switching loads. Maintenance requirements are minimised, helping businesses reduce downtime and achieve greater cost efficiency.

The PNOZ 15 24VDC is more than just a safety component—it is a core element in building a dependable safety control system. By combining low power consumption, versatile input/output options, and compliance with stringent safety standards, it offers machine builders and operators the peace of mind that personnel protection and process safety are guaranteed.

Whether protecting a standalone machine or forming part of a complex production line, the Pilz PNOZ 15 safety relay delivers the performance, reliability, and flexibility that modern industries demand.
