The Pilz PNOZ XV3.1P 30/24VDC 3N/O 1N/C 2N/O T (Part No. 777520) is a highly reliable safety relay engineered to provide robust monitoring of safety devices and dependable shutdown of hazardous machine functions. Part of the well-established PNOZ family, this relay combines energy-efficient operation, flexible contact options, and compliance with international safety standards, making it a versatile choice for machine safety applications.

Powered by a 24 V DC supply, the PNOZ XV3.1P consumes just 4.5 W, ensuring low operating costs and minimal heat generation in control cabinets. Its efficiency makes it suitable for continuous use in demanding industrial environments where uptime and energy savings are equally important.

The relay is designed with dual-channel input monitoring, enabling redundancy and fault detection. This ensures that critical safety devices—such as emergency stop pushbuttons, safety gates, guard interlocks, enabling switches, or light curtains—are reliably supervised. Dual-channel monitoring is essential for detecting wiring faults, cross faults, or discrepancies between channels, thereby preventing unsafe restarts and ensuring maximum protection for operators and machinery.

A key advantage of the PNOZ XV3.1P lies in its extensive output configuration. It provides 3 normally open (N/O) safety contacts for direct disconnection of hazardous machine operations, alongside 1 normally closed (N/C) contact for signalling or diagnostic purposes. In addition, it offers 2 time-delayed normally open (N/O) contacts, which are particularly valuable in applications requiring a staged or controlled shutdown. Time-delayed outputs allow motors, drives, or other moving parts to decelerate safely before full power isolation, reducing mechanical stress and ensuring process safety.

With compliance to EN 60947-4-1 (AC/DC1 utilisation category), the relay supports reliable switching performance for loads up to 240 V AC at 8 A. This high switching capacity ensures long service life and consistent performance even under frequent or heavy load conditions.

The compact housing and user-friendly terminal layout simplify installation, reduce commissioning time, and support efficient integration into both new and existing safety systems. The robust design ensures durability and reliable performance, even in environments subject to frequent actuation, vibration, or electrical disturbances.

Applications for the PNOZ XV3.1P span across automotive manufacturing, robotics, packaging machinery, food and beverage production, and material handling systems. It is particularly suitable for machinery where staged shutdowns are critical—for example, conveyors, rotating equipment, or press systems where controlled deceleration prevents damage and enhances operator safety.

In summary, the Pilz PNOZ XV3.1P 30/24VDC 3N/O 1N/C 2N/O T (777520) delivers efficient DC operation, flexible contact outputs including time-delayed options, dual-channel monitoring, and high switching capacity. It is a compact yet powerful safety relay designed to safeguard both operators and machinery while ensuring compliance with international safety standards.
