The Pilz PNOZ XV3.1P 30/24–240VACDC 3N/O 1N/C 2N/O T (Part No. 777530) is a versatile and high-performance safety relay designed to monitor essential safety functions in industrial machinery and automation systems. As part of the trusted Pilz PNOZ range, this model delivers outstanding flexibility through its wide voltage range, adaptable outputs, and robust compliance with international safety standards.

Operating on a broad supply voltage of 24–240 V AC/DC, the relay integrates seamlessly into both low-voltage and high-voltage systems. This wide compatibility reduces the need for multiple relay variants across different applications, simplifying procurement and standardisation for machine builders and operators. With a power consumption of 8.5 VA (AC) and 5 W (DC), it ensures efficient performance even during continuous operation, helping lower energy costs and improve thermal management inside control cabinets.

The PNOZ XV3.1P supports dual-channel input monitoring with 2 inputs, a key feature for enhancing fault detection and redundancy. This capability makes it highly reliable for monitoring safety devices such as emergency stop pushbuttons, two-hand control devices, safety mats, guard doors, and light curtains. Dual-channel monitoring ensures that cross faults, short circuits, or wiring errors are detected immediately, preventing unsafe machine restarts and guaranteeing operator protection.

A defining strength of this safety relay is its flexible output configuration. It provides 3 normally open (N/O) safety contacts for disconnecting hazardous energy sources, 1 normally closed (N/C) auxiliary contact for signalling and diagnostics, and 2 delayed N/O contacts for time-delayed shutdown applications. The inclusion of time-delayed outputs is particularly valuable in machinery where sequential shutdown of actuators or drives is required, ensuring safe deceleration or orderly stopping of processes before full power isolation.

Compliant with EN 60947-4-1 utilisation categories (AC/DC1), the PNOZ XV3.1P guarantees robust switching of loads under industrial conditions. Its design ensures long service life and reliable performance, even in demanding environments with frequent switching cycles or harsh operating conditions.

Installation is straightforward due to its compact design and clearly labelled terminals, which simplify wiring and commissioning. Integration with broader safety architectures is seamless, making it a practical choice for both new installations and retrofits of existing machinery.

The PNOZ XV3.1P is widely applied across industries including automotive, packaging, robotics, logistics, and process automation, where precise and reliable safety monitoring is essential. Its broad input voltage range, time-delayed outputs, and multiple safety contacts make it an excellent choice for complex safety circuits requiring flexibility and adaptability.

In summary, the Pilz PNOZ XV3.1P 30/24–240VACDC (777530) combines wide voltage compatibility, dual-channel monitoring, flexible contact configuration, and efficient operation. It is a powerful and adaptable safety relay designed to deliver reliable performance and ensure operator protection across diverse industrial environments.
