The Pilz PNOZ X2.9P 24VDC 3N/O 1N/C (Part No. 777300) is a reliable and compact safety relay designed to monitor safety functions and ensure machinery is safely brought to a stop when hazardous conditions arise. Belonging to the renowned Pilz PNOZ X series, this relay provides a cost-effective yet powerful solution for machine builders and operators who demand high standards of safety, efficiency, and compliance.

Operating on a 24 V DC supply, the PNOZ X2.9P has a low power consumption of only 2 W, making it an energy-efficient choice for applications where multiple relays are used in parallel. Its efficiency not only reduces energy costs but also helps limit heat generation in control cabinets, extending the lifespan of both the relay and surrounding equipment.

The relay is equipped with dual-channel input monitoring, with 2 inputs that provide redundancy and error detection. This ensures reliable supervision of safety devices such as emergency stop buttons, safety gates, enabling switches, or light curtains. Dual-channel monitoring significantly enhances fault tolerance by detecting wiring errors, short circuits, or discrepancies between input signals, ensuring machines cannot operate unless safety conditions are fully satisfied.

For outputs, the PNOZ X2.9P offers a robust contact configuration:

3 normally open (N/O) safety contacts for safely disconnecting actuators, motors, or other hazardous energy sources.

1 normally closed (N/C) auxiliary contact for status signalling or integration into diagnostic systems.

This configuration makes the relay highly versatile, enabling both direct switching of dangerous functions and monitoring through higher-level controllers or HMIs.

Built in compliance with EN 60947-4-1 utilisation category AC/DC1, the PNOZ X2.9P is certified for reliable switching of loads up to 240 V AC. Its rugged design ensures dependable performance even in demanding industrial environments subject to frequent switching cycles, vibration, or varying ambient conditions.

Installation and commissioning are straightforward thanks to the compact form factor and clearly labelled terminals, which minimise wiring errors and reduce setup times. Once installed, the relay delivers long-lasting performance with minimal maintenance requirements, ensuring both safety and productivity.

The PNOZ X2.9P is suitable for a wide range of industries, including manufacturing, packaging, robotics, automotive, and process automation. It is especially valuable in small to medium-sized machines where multiple safety contacts are required to reliably disable hazardous energy sources and provide auxiliary feedback.

In summary, the Pilz PNOZ X2.9P 24VDC 3N/O 1N/C (777300) combines energy-efficient DC operation, dual-channel safety monitoring, versatile output contacts, and standards-compliant performance. It is a robust and reliable safety relay designed to safeguard operators and equipment while supporting compliance with international machine safety standards.
