The Pilz PNOZ 11 24VAC / 24VDC 7N/O 1N/C (774080) is a high-capacity safety relay from the renowned PNOZ series, engineered to deliver reliable monitoring and control of safety functions in industrial automation. With its extensive contact set, dual input channels, and integrated semiconductor outputs, it provides a versatile solution for safeguarding personnel and machinery in compliance with international safety standards.

Designed for dual-channel input monitoring, the PNOZ 11 supervises two independent safety circuits, ensuring fault tolerance and high reliability. This makes it suitable for critical safety devices such as emergency stop buttons, protective gates, light curtains, or enabling switches. By monitoring both channels, the relay guarantees that hazardous machine movements are stopped safely, even if a single fault occurs, supporting compliance with EN ISO 13849-1 (PL e) and IEC 62061 (SIL 3).

One of the standout features of this relay is its extensive contact arrangement. With 7 normally open (N/O) safety contacts, it offers multiple fail-safe outputs that can be used to actuate contactors, disconnect drives, or stop motors across several parts of a machine simultaneously. The additional 1 normally closed (N/C) contact can be configured for signalling, enabling operators or higher-level control systems to monitor system status and detect when the relay has been triggered.

Beyond mechanical contacts, the PNOZ 11 also provides 2 semiconductor outputs, designed for auxiliary functions such as status feedback or communication with programmable logic controllers (PLCs). These solid-state outputs offer wear-free, rapid switching, further enhancing the device’s longevity and diagnostic capabilities.

Built for industrial robustness, the PNOZ 11 is rated for switching loads up to 240 V AC at 8 A, in compliance with EN 60947-4-1 utilisation categories. It also tolerates fluctuations in external DC voltage supply by -20% to +20%, ensuring stable operation in environments where supply quality may vary. Despite its powerful functionality, the unit remains compact and easy to install, with DIN-rail mounting simplifying integration into control panels.

The PNOZ 11 is widely applicable across industries such as automotive, packaging, robotics, process automation, and material handling, where multiple machine functions must be reliably secured. Its large number of safety contacts make it especially useful in systems where several actuators or redundant circuits must be controlled simultaneously, reducing the need for additional relays and simplifying overall safety architecture.

In summary, the Pilz PNOZ 11 24VAC / 24VDC 7N/O 1N/C (774080) is a versatile, high-capacity safety relay that combines dual-channel monitoring, extensive contact outputs, auxiliary semiconductor outputs, and robust switching performance. Engineered for reliability and compliance, it offers an ideal solution for protecting operators and equipment while simplifying the implementation of complex safety circuits in modern industrial environments.
