The Pilz PNOZ E4.1P C 24VDC 2SO (Part Number: 784180) is a dedicated safety relay designed for the reliable monitoring of safety mats and related protective devices. As part of Pilz’s highly trusted range of safety relays, it delivers dependable protection for both operators and machinery by ensuring immediate and safe system shutdown in hazardous situations.
Operating on a 24 V DC supply voltage, the PNOZ E4.1P C integrates seamlessly into modern industrial control systems. Its design is particularly optimised for safety mat applications, with a resistance monitoring capability of up to 150 ohms. This ensures that the relay can detect and react to the activation of safety mats with precision, providing a reliable safeguard against accidental or unsafe operator entry into hazardous zones.
The relay features two semiconductor outputs (SO), which provide solid-state switching for controlling safety-critical loads such as actuators, contactors, or machine shutdown mechanisms. Semiconductor outputs are especially valuable in safety systems due to their long service life, absence of mechanical wear, and fast, reliable response. This makes the PNOZ E4.1P C suitable for applications where frequent switching and long-term durability are essential.
For additional flexibility, the device supports external circuit protection with 6 A slow-blow fuses or 10 A quick-acting fuses. This allows system designers to tailor protection to the application’s needs, balancing between circuit endurance and rapid response to faults. Combined with Pilz’s robust internal design, this ensures both safety and system reliability.
Built in compliance with EN 60947-1 (utilisation category DC-12), the relay guarantees adherence to international electrical and safety standards. This compliance underscores its suitability for safety-critical applications, ensuring that it meets both regulatory and operational requirements across industries.
The PNOZ E4.1P C 24VDC 2SO is compact, easy to integrate, and robust, making it a reliable addition to safety systems in industries such as automotive manufacturing, packaging, logistics, robotics, and process automation. In all of these environments, the ability to reliably monitor safety mats and immediately disconnect hazardous machine functions is essential to protecting operators and preventing accidents.
In summary, the Pilz PNOZ E4.1P C 24VDC 2SO (784180) combines reliable monitoring of safety mats, dual solid-state safety outputs, flexible circuit breaker options, and standards-compliant design. By integrating this safety relay, engineers and operators can ensure that their machines operate safely, efficiently, and in compliance with international safety directives, while maintaining high levels of productivity and uptime.
