The Pilz PNOZ XV3P 0.5/24VDC 3N/O 2N/O T FIX – 777514 is a high-performance safety relay engineered to monitor critical safety functions in industrial automation. Part of the proven PNOZ XV series, it combines robust safety logic, flexible output options, and energy-efficient operation to safeguard both operators and machinery.

Designed for use with a 24 V DC power supply, this relay integrates seamlessly into modern low-voltage industrial control systems. It is particularly well-suited for installations where compact control panels and distributed I/O systems require reliable safety monitoring.

One of the defining features of this model is its contact configuration, which includes three immediate normally open (N/O) contacts and two time-delayed N/O contacts. This arrangement allows engineers to design flexible safety circuits that balance immediate risk mitigation with controlled process shutdowns. For example, hazardous machine movements can be stopped instantly via the immediate contacts, while auxiliary systems such as conveyors or cooling fans can be shut down in a sequenced, time-controlled manner to prevent mechanical stress or system damage.

The dual-channel input design enhances safety integrity by providing redundancy and enabling fault detection. This ensures compliance with international standards, such as EN 60947-4-1, and supports safety categories up to Performance Level (PL) and Safety Integrity Level (SIL) as required in machine safety.

In terms of efficiency, the relay has a DC power consumption of just 4.5 W, making it economical to operate even in large-scale installations with multiple relays. Its compact, fixed design simplifies mounting, wiring, and maintenance, reducing installation costs while ensuring robust performance in continuous-duty environments.

The PNOZ XV3P 0.5/24VDC is ideally suited for monitoring devices such as emergency stop buttons, safety gates, light curtains, and two-hand control systems. Its flexibility and reliability make it an excellent choice across a wide range of industries, including automotive manufacturing, packaging, robotics, process automation, and material handling.

By combining immediate and delayed safety contacts with efficient power usage, the relay enables safety engineers to implement layered protection strategies, where different machine functions can be shut down according to urgency. This not only enhances operator protection but also reduces unnecessary wear and tear on equipment.

In summary, the Pilz PNOZ XV3P 0.5/24VDC 3N/O 2N/O T FIX – 777514 is a compact, flexible, and energy-efficient safety relay designed for modern automation systems. With dual-channel monitoring, a mix of immediate and time-delay outputs, and robust compliance with international safety standards, it delivers a powerful solution for safeguarding machinery while supporting efficient, reliable industrial operation.
