The Pilz PNOZ E5.11P C 24VDC 2SO (part no. 784190) is a specialised safety relay from the proven Pilz PNOZ range, developed to ensure safe, efficient, and standards-compliant monitoring of safety functions in industrial automation. With its semiconductor output technology and compliance with rigorous international standards, it is particularly well-suited for applications demanding high switching frequencies and long service life.

Operating at a 24 V DC supply voltage, the relay integrates seamlessly into modern low-voltage safety architectures. This makes it highly compatible with widely used control systems and simplifies implementation across diverse machine types. Its design supports stable performance in continuous duty, ensuring reliability in demanding industrial conditions.

A key strength of this model is its two solid-state (semiconductor) outputs. Unlike mechanical relays, semiconductor outputs enable fast, precise, and wear-free switching. This feature is particularly valuable in applications involving high actuation rates, where traditional relay contacts may degrade over time. With solid-state technology, the PNOZ E5.11P C ensures consistent reliability, minimal maintenance, and extended service life.

The device is also designed for circuit protection flexibility, supporting the use of either a 6 A slow-blow fuse or a 10 A quick-acting fuse. This adaptability ensures reliable protection against overloads and short circuits, safeguarding both the relay and connected devices.

Built to comply with EN 60947-1 (DC-12 utilisation category), the relay is validated for switching resistive loads under direct current, ensuring predictable and safe performance in DC-powered systems. Additionally, it meets EN 60068-2-78 climatic suitability, confirming its resilience in humid industrial environments. This environmental robustness makes it suitable for facilities where high moisture levels or fluctuating climate conditions may be present.

The compact and robust design of the PNOZ E5.11P C simplifies panel integration, with clear terminal assignments for fast wiring and commissioning. Its solid-state outputs reduce heat and wear, which contributes to efficient long-term performance and lower maintenance demands.

In practical applications, the PNOZ E5.11P C is ideal for monitoring safety devices such as emergency stop pushbuttons, protective doors, light curtains, and enabling switches. It ensures hazardous machine functions are disabled immediately when unsafe conditions are detected, supporting compliance with international safety standards like ISO 13849-1 and IEC 62061.

Industries such as automotive manufacturing, packaging, robotics, logistics, and metalworking benefit from the device’s reliability and durability. Its ability to handle frequent switching without mechanical wear makes it an excellent choice for highly automated environments.

In summary, the Pilz PNOZ E5.11P C 24VDC 2SO is a reliable and efficient safety relay that combines semiconductor output technology with standards-compliant performance. With its 24 V DC supply, dual solid-state outputs, circuit protection flexibility, and climatic resilience, it delivers dependable safeguarding for both operators and equipment in modern industrial automation systems.
