The Pilz PNOZ 10 24VDC 6N/O 4N/C (774009) is a versatile and robust safety relay designed for reliable machine safety monitoring across a wide range of industrial environments. As part of the highly trusted Pilz PNOZ series, this relay is engineered to safeguard personnel and machinery by supervising safety inputs and enabling safe, controlled switching of outputs.

At the heart of the PNOZ 10 is its dual-channel input monitoring system, which allows for redundant control of safety devices such as emergency stop buttons, safety gates, or light curtains. By monitoring two separate input circuits, the relay ensures a high degree of fault tolerance, preventing single-point failures from compromising overall system safety. This makes it compliant with stringent international safety standards and well-suited for use in critical automation applications.

The standout feature of this relay is its extensive contact arrangement, offering a total of ten contacts: six normally open (N/O) safety contacts and four normally closed (N/C) auxiliary contacts. The N/O contacts provide fail-safe actuation for machinery shutdown, ensuring that hazardous operations cease immediately when a safety condition is triggered. The N/C contacts, meanwhile, can be used for auxiliary functions such as fault indication, control feedback, or status signalling. This configuration provides engineers with the flexibility to design sophisticated safety circuits while reducing the need for additional relays.

Operating on a 24 VDC supply, the PNOZ 10 is easy to integrate into modern low-voltage control systems. Its 5.5 W power consumption ensures efficient operation, making it a cost-effective solution for installations where multiple relays may be deployed across a plant. Despite its low energy footprint, the relay delivers robust switching performance up to 240 V AC, in accordance with EN 60947-4-1 utilisation categories, ensuring long service life even under heavy-duty operation.

Installation and setup are straightforward thanks to its compact housing, which is designed for DIN rail mounting. Clearly labelled terminals simplify wiring and reduce installation time, while the rugged construction ensures durability in demanding conditions such as automotive manufacturing, robotics, packaging, and process industries.

Another benefit of the PNOZ 10 is its contribution to maintenance efficiency. With dedicated auxiliary contacts for signalling, operators gain better visibility into system status and fault conditions, enabling faster diagnostics and reducing downtime. This feature, combined with its robust design, makes the relay an ideal choice for businesses seeking to improve both safety and productivity.

In summary, the Pilz PNOZ 10 24VDC 6N/O 4N/C (774009) offers a powerful combination of high contact availability, dual-channel safety monitoring, and energy-efficient operation. Its extensive contact set and compliance with international safety standards make it a reliable and flexible solution for safeguarding machinery and personnel across diverse industrial applications.
