The Pilz PNOZ E6VP 24VDC 4N/O 1SO 1SO T (part no. 774193) is a versatile safety relay designed to provide secure monitoring of safety functions in industrial applications. Part of the trusted Pilz PNOZ range, this device ensures that safety-related commands are executed quickly and reliably, forming a critical component in safeguarding personnel, machinery, and processes.

Operating with a 24 VDC supply voltage, the PNOZ E6VP is optimised for modern industrial control systems, which increasingly rely on low-voltage DC architectures for both safety and efficiency. This makes it highly suitable for integration into diverse applications, from machinery with decentralised control systems to complex automation environments where reliable low-voltage operation is essential.

The relay offers a flexible contact configuration, featuring 4 normally open (N/O) safety contacts and 2 signalling outputs (SO). The N/O contacts are used to enable machine functions only when safety conditions are satisfied, while the signalling outputs provide status or diagnostic feedback to control systems. This dual capability allows engineers to not only enforce safety but also monitor system performance in real time, improving transparency and maintainability.

To ensure robust and compliant performance, the PNOZ E6VP meets the utilisation categories specified by international standards. It is rated to EN 60947-1 (DC-12 utilisation category) and EN 60947-4-1 (AC/DC1 utilisation category), demonstrating its ability to handle both DC and AC switching duties reliably. These certifications highlight the device’s suitability for applications requiring dependable switching performance across a range of operating conditions.

The design also incorporates circuit protection compatibility, supporting installation with either a 6 A slow-blow fuse or a 10 A quick-acting fuse. This flexibility ensures reliable coordination with upstream protection devices, minimising the risk of damage from overloads or short circuits. The result is a more resilient safety circuit that can withstand the rigours of daily industrial operation.

Built with Pilz’s renowned focus on durability and ease of integration, the PNOZ E6VP is compact, reliable, and straightforward to install. Its sturdy construction ensures consistent performance, even in environments subject to mechanical stress, temperature fluctuations, or continuous operation. With its modular design philosophy, it can be easily incorporated into both new installations and retrofit projects without extensive modification.

Typical applications for the PNOZ E6VP include monitoring of emergency stop functions, guard doors, two-hand control systems, and light barriers. In each case, the relay ensures immediate shutdown of dangerous machinery in the event of a hazard, while its signalling outputs provide essential feedback for diagnostics and control.

In summary, the Pilz PNOZ E6VP 24VDC 4N/O 1SO 1SO T is a robust and flexible safety relay that combines multiple enabling and signalling outputs with compliance to international standards. With its reliable DC operation, protective circuit design, and proven Pilz engineering, it offers a dependable solution for safeguarding industrial processes while maintaining high system uptime.
