The Pilz PNOZ E5.13P 24VDC 2SO, part number 774191, is a reliable and versatile safety relay engineered to monitor safety functions and ensure controlled shutdown of hazardous machine movements. As part of the Pilz PNOZ E series, this device combines robust safety features, efficient operation, and high-quality construction, making it a trusted choice for industrial environments where operator protection and system reliability are paramount.

Operating on a 24 V DC supply, the PNOZ E5.13P is optimised for compatibility with modern automation systems, where 24 V control voltage is the industry standard. Its low power requirements ensure efficient operation, supporting cost-effective integration in both new and retrofitted systems.

The relay provides 2 signalling outputs (SO), which are critical for enhancing system transparency and diagnostics. These outputs allow feedback to higher-level controllers such as PLCs or monitoring systems, giving operators and maintenance teams clear visibility of the relay’s operational status. This functionality supports proactive maintenance, faster fault detection, and improved system uptime.

For safe and reliable circuit design, the PNOZ E5.13P is compatible with protective devices rated at 6 A slow-blow or 10 A quick-acting circuit breakers. This ensures reliable protection of the relay against overcurrents while maintaining proper coordination with other electrical components in the control panel. By incorporating this level of circuit protection, the relay reduces the risk of damage, enhances system robustness, and supports long-term reliability.

Another defining feature of this unit is its compliance with EN 60947-1 (utilisation category DC-12), which ensures it is suitable for switching resistive loads in DC circuits. This makes it well-suited for a wide range of industrial applications where both control and safety circuits rely on low-voltage DC operation.

The relay is also designed and tested for climatic suitability in accordance with EN 60068-2-78, ensuring reliable performance under environmental stress such as humidity and temperature variations. This robust design means the PNOZ E5.13P can be deployed confidently across industries with demanding operating conditions.

Applications for the PNOZ E5.13P include monitoring devices such as emergency stop pushbuttons, safety gates, light curtains, and two-hand control systems. When activated, the relay ensures immediate disconnection of hazardous energy, bringing machinery to a safe state and protecting personnel from injury.

In summary, the Pilz PNOZ E5.13P 24VDC 2SO (774191) is a durable, standards-compliant safety relay designed for modern industrial safety systems. With its 24 V DC operation, dual signalling outputs, robust circuit breaker compatibility, and proven environmental resilience, it provides a dependable solution for safeguarding operators and machinery across a wide variety of applications.
