The Pilz PNOZ E1VP 10/24VDC 1SO 1SO T (774131) is a compact and efficient safety relay designed for dependable monitoring and switching of safety-related functions in DC-powered industrial control systems. As part of the established PNOZ range, it combines robustness, flexibility, and compliance with international safety standards to ensure the highest levels of protection for both operators and equipment.
At the heart of the PNOZ E1VP is its dual semiconductor output design. The unit provides one immediate OSSD (Output Signal Switching Device) output and one time-delayed OSSD output, enabling both instant safety actions and controlled shutdown sequences. This arrangement gives engineers greater flexibility when designing safety architectures—supporting fast machine stop functions while also allowing staggered power-down of equipment such as motors, conveyors, or high-inertia drives.
Designed for 24 V DC operation, the relay is fully compatible with modern low-voltage safety and control systems. It is protected by a 6 A slow-blow or 10 A quick-blow circuit breaker, ensuring safe and stable operation even under varying load conditions. Its classification under EN 60947-1 DC-12 utilisation category highlights its suitability for reliably handling standard DC control circuits, making it ideal for widespread industrial use.
The PNOZ E1VP also stands out for its environmental durability. Tested in accordance with EN 60068-2-78 climatic suitability standards, the unit is capable of withstanding demanding conditions, including heat and humidity. It operates reliably across an ambient temperature range of -10 °C to +55 °C, making it suitable for a broad range of industrial settings—from temperature-controlled production environments to standard shop floors.
Built with Pilz’s hallmark reliability, the relay’s solid-state outputs offer rapid and wear-free switching, minimising mechanical wear and extending the device’s operational lifespan. This makes it a particularly good fit for applications with high switching frequencies, where electromechanical relays might suffer from reduced longevity.
Installation is made simple through its compact modular design, which is optimised for DIN-rail mounting. Clearly labelled terminals ensure quick wiring and reduce the risk of errors during commissioning. Once installed, the device requires little maintenance, helping to reduce system downtime and improve productivity.
Applications for the PNOZ E1VP include monitoring of emergency stop circuits, safety gates, and protective equipment in sectors such as packaging, logistics, process automation, and general machine building. Its combination of immediate and delayed OSSD outputs makes it especially effective in environments where controlled stopping sequences are essential.
In summary, the Pilz PNOZ E1VP 10/24VDC 1SO 1SO T (774131) is a flexible, robust, and efficient safety relay that combines dual semiconductor outputs, DC compatibility, and environmental resilience. With its proven reliability and compliance with international standards, it offers an ideal solution for ensuring operator safety and machine protection across a wide range of industrial applications.
