The Pilz PNOZ X3 24VAC 24VDC 3N/O 1N/C 1SO – 774310 is a versatile and reliable safety relay designed to safeguard machinery and operators by monitoring emergency stop devices and safety gates. As part of the proven PNOZ X series, this relay combines robust performance, multiple output options, and flexible supply compatibility, making it an essential safety component for a wide range of industrial applications.

Engineered to work with a 24 V AC supply as its primary power source and a 24 V DC secondary voltage, the PNOZ X3 offers excellent flexibility for integration into different electrical architectures. This dual-supply configuration ensures adaptability in diverse environments, whether the system is based on traditional AC power distribution or modern DC-controlled safety circuits.

The relay is equipped with three normally open (N/O) enabling contacts, one normally closed (N/C) contact, and one signalling output (SO). This output configuration provides significant wiring flexibility for system designers. The N/O contacts ensure safe disconnection of actuators, motors, or contactors when a fault or emergency stop occurs. The N/C contact can be used for additional circuit monitoring or feedback loops, while the SO provides clear signalling of the relay’s operational status to higher-level control systems. This combination of outputs supports both reliable safety switching and effective diagnostics.

To maximise safety integrity, the PNOZ X3 features two safety inputs for dual-channel monitoring. This redundancy ensures faults such as wiring errors, short circuits, or contact failures are reliably detected, reducing the risk of undetected safety device failures. It is ideally suited for monitoring devices such as emergency stop buttons, safety gates, and light curtains, where fail-safe functionality is mandatory.

With a power consumption of just 5 VA in AC operation, the relay is energy efficient while maintaining robust performance. Its compact form factor and durable construction make it easy to install in control cabinets and suitable for continuous use in demanding industrial environments.

Typical applications for the PNOZ X3 include use in packaging lines, robotics, automated assembly, processing machinery, and general manufacturing systems. Wherever operator protection and machine safety compliance are critical, this relay delivers reliable monitoring and safe machine shutdown.

In summary, the Pilz PNOZ X3 24VAC 24VDC 3N/O 1N/C 1SO – 774310 offers a practical blend of dual-supply compatibility, multiple contact outputs, and robust dual-channel safety monitoring. It is a compact, efficient, and standards-compliant solution for safeguarding modern industrial equipment and ensuring uninterrupted productivity.
