The Pilz PNOZ 1 230–240VAC 3N/O 1N/C (Part No. 775650) is a robust and reliable safety relay designed for industrial applications requiring dependable monitoring of safety functions. As part of the well-established PNOZ series, this relay provides a trusted solution for safeguarding operators and equipment, combining proven safety technology with ease of integration into a wide range of systems.

Operating at a supply voltage of 230–240 VAC, the PNOZ 1 is suitable for direct connection to standard AC mains power without the need for additional conversion equipment. With a power consumption of just 5.5 VA, it offers an efficient solution that balances performance with energy savings, making it well-suited for continuous operation in industrial environments.

The relay features two safety inputs, enabling dual-channel monitoring of protective devices such as emergency stop pushbuttons, safety gates, or enabling switches. This dual-channel architecture ensures redundancy and fault detection, both essential for maintaining a high level of safety integrity. By monitoring inputs independently, the PNOZ 1 guarantees that faults can be detected quickly, preventing hazardous machine restart or unsafe operation.

Its output configuration provides three normally open (N/O) contacts and one normally closed (N/C) contact, allowing for flexible integration into safety circuits. The N/O contacts can be used to directly control actuators, motors, or contactors, while the N/C contact offers monitoring and feedback functionality. This arrangement ensures reliable shutdown of hazardous functions while providing the flexibility needed for advanced safety concepts.

Built to comply with EN 60947-4-1 utilisation categories for AC/DC1, the PNOZ 1 guarantees that it meets international safety and electrical performance standards. This compliance makes it suitable for integration into machinery that requires adherence to performance level and safety integrity standards such as EN ISO 13849-1 or IEC 62061. By ensuring conformity, the relay supports manufacturers and plant operators in meeting regulatory obligations while protecting personnel.

The design of the PNOZ 1 reflects Pilz’s emphasis on durability and ease of use. Its compact form factor allows easy installation into control cabinets, even in space-constrained environments. The relay’s long operational life and rugged construction reduce the need for frequent replacements, cutting downtime and maintenance costs. Additionally, straightforward wiring and clear labelling make commissioning fast and error-free.

Industries such as manufacturing, packaging, material handling, and process engineering benefit from the proven reliability of the PNOZ 1. Whether safeguarding standalone machinery or integrated into complex production systems, this safety relay delivers reliable protection, efficient performance, and compliance with the highest standards of safety.

In summary, the Pilz PNOZ 1 230–240VAC combines trusted performance, flexible contact options, and robust compliance—making it an essential choice for engineers and operators seeking a dependable safety solution for AC-powered machinery.
