The Pilz PNOZ E5.11P 24VDC 2SO (Part Number: 774190) is a reliable and high-performance safety relay engineered to safeguard machines and personnel by providing robust monitoring and control of safety functions. As part of Pilz’s trusted PNOZ series, it combines durability, efficiency, and compliance with international standards to support safety-critical operations in modern industrial automation.

Operating on a 24 V DC supply voltage, the relay integrates seamlessly into contemporary control cabinets and distributed automation systems. It is equipped with two semiconductor safety outputs (SO), offering fast, wear-free switching performance. Unlike mechanical relay contacts, semiconductor outputs do not suffer from contact erosion, ensuring an extended service life and high reliability in applications with frequent switching cycles.

The relay also provides flexible external circuit protection options, supporting the use of 6 A slow-blow or 10 A quick-acting fuses. This flexibility allows engineers to tailor the device to the application’s specific demands, ensuring that the safety relay and downstream components are adequately protected against overloads or short circuits.

One of the defining characteristics of the PNOZ E5.11P is its environmental robustness. It has been tested and certified to EN 60068-2-78, confirming its ability to perform reliably under demanding climatic conditions, including variations in temperature and humidity. This makes it well-suited for environments where resilience is critical, whether in controlled manufacturing spaces or more variable process industry applications.

In addition, the relay complies with EN 60947-1 (utilisation category DC-12), ensuring reliable operation when switching resistive DC loads. This compliance guarantees that the PNOZ E5.11P meets international safety and electrical performance standards, providing peace of mind for both machine builders and system operators.

Compact and efficient in design, the PNOZ E5.11P 24VDC 2SO is easy to integrate into new and existing systems. It is particularly well-suited for monitoring and controlling devices such as emergency stop buttons, safety mats, guard doors, light curtains, or two-hand control systems. Its solid-state outputs also make it an excellent choice for integration with diagnostic systems, providing transparency and facilitating predictive maintenance strategies.

The relay is widely applied in industries including automotive, packaging, robotics, logistics, and process automation, where the safe shutdown of hazardous movements and compliance with safety directives are non-negotiable. By combining semiconductor reliability with Pilz’s proven safety expertise, the PNOZ E5.11P ensures uptime, system integrity, and personnel protection.

In summary, the Pilz PNOZ E5.11P 24VDC 2SO (774190) is a robust and versatile safety relay designed to deliver long-term, standards-compliant protection. With dual solid-state safety outputs, certified environmental resistance, and flexible protection options, it provides a dependable solution for ensuring machine safety and maintaining efficient industrial operations.
