The Pilz PNOZ E1VP C 10/24VDC 1SO 1SO T (Part No. 784131) is a specialised safety relay engineered for monitoring safety functions in industrial automation environments. As part of Pilz’s well-regarded PNOZ product line, this relay delivers reliable safety performance with semiconductor-based outputs and time-delay functionality, making it a versatile solution for safeguarding machinery and operators.
Operating on a 24 V DC supply, the PNOZ E1VP C is optimised for modern control systems where low-voltage operation is standard. Its low-voltage design ensures safe integration while supporting energy efficiency in continuous duty applications. With low power consumption and robust switching capability, it provides consistent performance in demanding industrial settings.
The relay is equipped with two semiconductor outputs: one standard and one time-delayed (SO T). This configuration enables flexible design of safety circuits, supporting both immediate and controlled disconnection of machine functions. The immediate SO provides instant shutdown of hazardous energy sources, while the time-delayed SO allows sequential power-down of auxiliary components or systems that require controlled stopping. This flexibility makes the relay particularly valuable in applications such as conveyors, presses, or complex machinery where staged shutdown enhances both safety and process integrity.
In terms of electrical protection, the PNOZ E1VP C is rated under the DC-12 utilisation category according to EN 60947-1, ensuring suitability for switching resistive DC loads. It also supports protection through circuit breakers rated at 6 A slow-blow or 10 A quick-acting fuses, helping safeguard both the relay and connected equipment against overload conditions.
Built with environmental resilience in mind, the device is tested for climatic suitability according to EN 60068-2-78. This certification ensures reliable performance in environments with humidity and temperature variations, making it suitable for a wide range of industrial applications. Its durable design guarantees long service life even in harsh conditions, reducing downtime and maintenance requirements.
The PNOZ E1VP C 10/24VDC 1SO 1SO T is ideally suited for monitoring emergency stop devices, guard doors, light curtains, and other safety-related inputs. Its ability to combine instant and delayed switching provides engineers with flexibility to design tailored safety architectures while maintaining compliance with international safety standards.
Applications include manufacturing, packaging, process control, robotics, and material handling industries, where reliable shutdown and operator protection are critical. In each case, the PNOZ E1VP C ensures machines are safely stopped under hazardous conditions while supporting controlled operations during shutdown sequences.
In summary, the Pilz PNOZ E1VP C 10/24VDC 1SO 1SO T delivers reliable DC operation, flexible semiconductor outputs, robust electrical protection, and certified environmental durability. It is a dependable safety relay that enhances both machine safety and operational efficiency, making it an essential component in modern automation environments.
