The Pilz PNOZ E3.1P C 24VDC 2SO (Part Number: 784139) is a compact, robust, and reliable safety relay designed for monitoring safety functions in industrial automation. As part of Pilz’s well-regarded PNOZ range, it provides dependable protection for operators and machines while maintaining compliance with international safety standards.

Operating from a 24 V DC supply voltage, the PNOZ E3.1P C integrates easily into modern control panels and distributed automation systems. The relay is equipped with two semiconductor safety outputs (SO), offering fast, wear-free switching. Unlike mechanical contacts, semiconductor outputs are not subject to physical wear and tear, ensuring a long operational life and reducing maintenance requirements. This makes the relay especially valuable in applications with frequent switching demands.

For added safety and flexibility, the device supports the use of external device circuit breakers rated 6 A (slow-blow) or 10 A (quick-acting). This ensures that the relay and connected circuits are properly protected against overloads or short circuits, further enhancing the durability and safety of the installation.

The PNOZ E3.1P C is tested in accordance with EN 60068-2-78, verifying its climatic suitability. This means it is proven to operate reliably in varying environmental conditions, including exposure to humidity and temperature fluctuations. Such resilience ensures the relay’s consistent performance across a broad range of industrial applications, from clean production floors to challenging environments.

Additionally, the unit complies with EN 60947-1 utilisation category DC-12, ensuring reliable operation when switching resistive DC loads. This compliance underscores the relay’s suitability for safety-critical applications and guarantees consistency with international standards for electrical equipment in industrial systems.

Practical in design, the relay’s compact size and modular concept allow engineers to integrate it easily into existing systems or new projects. It is ideal for monitoring and controlling safety devices such as emergency stop buttons, safety gates, light curtains, and two-hand control stations. Its dual outputs also make it suitable for controlling multiple actuators or integrating with diagnostic systems for real-time visibility.

The PNOZ E3.1P C 24VDC 2SO is widely applied across industries such as automotive, packaging, robotics, material handling, and process automation. In each of these sectors, it delivers consistent, standards-compliant safety performance, protecting both operators and equipment from hazards while ensuring high system availability.

In summary, the Pilz PNOZ E3.1P C 24VDC 2SO (784139) is a versatile and dependable safety relay that combines dual semiconductor outputs, flexible protection options, environmental robustness, and compliance with key international standards. Compact yet powerful, it ensures safe, reliable, and efficient performance in industrial safety applications.
