The Pilz PNOZ E1.1P 24VDC 2SO (Part No. 774133) is a compact and efficient safety relay designed for monitoring and controlling essential safety functions in industrial machinery. It belongs to the highly reliable Pilz PNOZ family, renowned for delivering robust safety performance and ensuring compliance with international safety regulations.
Powered by a 24 V DC supply, the PNOZ E1.1P provides energy-efficient performance that makes it suitable for continuous operation in modern automation systems. Its design incorporates two semiconductor outputs (SO), which enable fast, reliable, and wear-free switching of safety-related signals. Unlike electromechanical outputs, semiconductor outputs reduce mechanical wear, extending service life while maintaining dependable functionality even in high-cycle applications.
The device is compliant with the EN 60947-1 utilisation category DC-12, ensuring reliable performance when switching resistive or slightly inductive DC loads. With support for maximum device circuit breakers of 6 A (slow) or 10 A (quick), the relay provides strong electrical durability and safety for connected components, guaranteeing reliable operation under varying load conditions.
Environmental suitability is another key strength of the PNOZ E1.1P. It has been tested to EN 60068-2-78 climatic standards, making it resilient against industrial humidity and long-term environmental stress. With an operating temperature range of -10 °C to +55 °C, it is capable of performing reliably across a wide range of applications, from standard factory floor conditions to warmer or more humid installations.
The compact and modular design of the relay allows for straightforward installation into control panels, saving valuable space in automation systems. Its clearly labelled terminals and efficient wiring options reduce commissioning time, while its solid construction ensures minimal maintenance requirements and long service life.
Applications of the PNOZ E1.1P are diverse, spanning industries such as automotive manufacturing, robotics, packaging, pharmaceuticals, food and beverage processing, and material handling. It is particularly well-suited to safety functions where reliable and fast switching is required, such as monitoring guard doors, emergency stop circuits, or light curtains. The dual semiconductor outputs also allow for integration with higher-level controllers or distributed automation systems, improving system responsiveness and diagnostic transparency.
By combining DC efficiency, dual semiconductor outputs, compliance with global standards, and environmental resilience, the PNOZ E1.1P offers a high level of protection and flexibility. It provides machine builders and operators with a reliable safety solution that enhances both operator security and machine performance, ensuring compliance with safety regulations while supporting productivity.
In summary, the Pilz PNOZ E1.1P 24VDC 2SO (774133) delivers low-power DC operation, robust safety switching, environmental durability, and compliance with international standards. It is a compact yet powerful relay solution, designed to provide reliable safety functionality across a wide range of industrial automation applications.
