The Pilz PNOZ XV3P 300/24VDC 3N/O 2N/O T (777518) is a versatile safety relay from the proven PNOZ family, designed to provide reliable monitoring of safety functions in industrial machinery. Known for their robustness and compliance with international safety standards, PNOZ relays form the backbone of countless machine safety architectures worldwide. This model delivers a combination of efficiency, flexibility, and dependable performance in compact form.
At the core of its design, the unit features two independent input channels, allowing it to safely monitor devices such as emergency stop buttons, guard doors, light curtains, or other safety sensors. With dual-channel monitoring, the relay achieves high fault tolerance, ensuring that hazardous movements are reliably halted whenever safety conditions are not met. This makes it particularly suitable for applications where redundancy and reliability are paramount.
The relay is equipped with five safety outputs in total, comprising three normally open (N/O) contacts and two additional N/O contacts. These multiple outputs allow for the simultaneous actuation of several actuators or safety-related devices, such as contactors, solenoid interlocks, or signalling lamps. This ensures flexibility in system design, enabling a single relay to protect multiple parts of a machine or to provide both control and diagnostic feedback to the wider safety architecture.
Energy efficiency is another strength of the PNOZ XV3P 300/24VDC. Operating on a 24 V DC supply voltage with a modest power consumption of only 4.5 W, the relay ensures low energy use while maintaining reliable performance. This efficiency reduces operational costs and minimises heat generation inside the control cabinet, which contributes to overall system stability and longevity.
The device complies with EN 60947-4-1 utilisation category AC/DC1, providing assurance that it meets rigorous international standards for switching performance and durability. This compliance reflects Pilz’s commitment to designing products that support safety integrity levels required by global regulations, giving system designers confidence in both compliance and functionality.
Physically, the relay is built with Pilz’s hallmark durability and ease of integration. It is compact enough to fit neatly into control cabinets, yet robust enough to withstand the environmental stresses of industrial operation. The design simplifies wiring and installation, reducing commissioning time and ongoing maintenance requirements.
In practical terms, the PNOZ XV3P 300/24VDC 3N/O 2N/O T is suited for a wide range of industries, from automotive and packaging to manufacturing and materials handling. It ensures that when an unsafe condition arises—whether through an operator’s emergency stop action or the activation of a guard switch—the machinery responds immediately and reliably.
In summary, this safety relay delivers dual-channel monitoring, multiple safety outputs, low power consumption, and certified compliance with EN standards. As part of the trusted Pilz PNOZ family, it provides a dependable solution for safeguarding operators and machinery in today’s demanding industrial environments.
