The Pilz PNOZ E4VP 10/24VDC 1SO 1SO T, part number 774181, is a specialised safety relay engineered for monitoring and controlling safety mats and other pressure-sensitive protective devices. As part of the PNOZ E series, this unit combines Pilz’s expertise in functional safety with features tailored for floor-level safeguarding, offering dependable personnel protection in hazardous machine environments.

Operating on a 24 V DC supply, the PNOZ E4VP ensures stable, energy-efficient performance in modern automation systems. Its low-voltage operation makes it well suited for a wide range of industries, from manufacturing to packaging, where compatibility with 24 V control systems is the standard.

One of the relay’s core strengths is its dedicated design for safety mat applications. With a safety mat resistance specification of 150 Ω, the relay ensures precise monitoring of connected mats, reliably detecting the presence of personnel in dangerous zones. This functionality is vital in environments where operators may be working close to hazardous machinery and need immediate protection when stepping into restricted areas.

The device is equipped with two signalling outputs (SO), which provide clear and reliable feedback to higher-level controllers, PLCs, or diagnostic systems. These outputs enhance visibility of system status, supporting effective monitoring, maintenance, and troubleshooting. The signalling outputs also help ensure rapid response times, reinforcing the safety integrity of the system.

The PNOZ E4VP is engineered for robust safety compliance, meeting the requirements of EN 60947-1 utilisation category DC-12, making it suitable for controlling resistive DC loads. It is designed to work with protective devices rated at 6 A slow-blow or 10 A quick-acting circuit breakers, ensuring reliable protection and coordination within control panels. This compliance guarantees that the relay not only performs effectively but also adheres to international safety regulations, a necessity in today’s industrial environments.

The unit’s compact electromechanical design allows for straightforward installation in control cabinets, while its durable construction ensures long service life under continuous operation. It is particularly suited for environments with frequent operator interaction and high safety demands, where both personnel and machines must be protected without compromising productivity.

Typical applications for the PNOZ E4VP include production lines, packaging machinery, robotic cells, and material handling systems, where floor-level safety mats are essential for monitoring operator presence. By ensuring that dangerous machine operations are halted as soon as a mat is stepped on, the relay provides effective, user-friendly protection against accidents.

In summary, the Pilz PNOZ E4VP 10/24VDC 1SO 1SO T (774181) is a robust and reliable safety relay designed for safety mat monitoring. With its 24 V DC operation, dual signalling outputs, compliance with international standards, and precise resistance monitoring, it provides an effective and trusted solution for safeguarding personnel and machinery in modern industrial settings.
