The Pilz PNOZ X3 230VAC 24VDC 3N/O 1N/C 1SO – 774318 is a versatile safety relay designed for monitoring emergency stop functions and protective devices in industrial machinery and process equipment. As part of the Pilz PNOZ X series, this unit combines flexibility, reliability, and compliance with international safety standards to deliver secure machine shutdown and operator protection.

This model is engineered with a dual supply system. It utilises 230 V AC as the main operating voltage while supporting a 24 V DC secondary supply, making it adaptable to a wide range of machine configurations and control cabinet designs. This capability ensures compatibility with both traditional AC-powered systems and modern DC-based control infrastructures, simplifying integration in mixed-environment facilities.

The PNOZ X3 stands out with its comprehensive output configuration, providing three normally open (N/O) enabling contacts, one normally closed (N/C) contact, and one signalling output (SO). The N/O contacts allow for the reliable control of actuators and contactors, ensuring hazardous machine functions are shut down safely when required. The N/C contact can be used for additional monitoring, such as detecting faults or establishing feedback loops, while the signalling output delivers status information directly to the control system. Together, these outputs provide flexible wiring options and enhanced diagnostic visibility.

With two redundant safety inputs, the relay supports dual-channel monitoring, enabling detection of wiring errors, shorts, or contact faults. This redundancy ensures compliance with higher safety requirements, reinforcing the system’s integrity and reliability. The design is particularly suited for monitoring devices such as emergency stop pushbuttons, safety gates, and light curtains, where fail-safe operation is essential.

Operating at a modest 5 VA power consumption under AC supply, the PNOZ X3 offers efficiency while maintaining robust performance. Its durable design ensures a long service life, even in demanding industrial environments where frequent actuation and continuous operation are standard. Installation is straightforward thanks to clearly labelled terminals and a compact housing, helping reduce setup time and simplifying maintenance.

Typical applications for the PNOZ X3 include packaging machinery, production lines, robotics, and general automation systems, where operator safety and machinery protection must be guaranteed. Its wide-ranging compatibility and output diversity make it a preferred choice for system designers looking for a balance between functionality and reliability.

In summary, the Pilz PNOZ X3 230VAC 24VDC 3N/O 1N/C 1SO – 774318 offers dual-supply flexibility, robust multi-contact outputs, and dependable dual-channel monitoring, delivering a compact and efficient solution for safeguarding machinery in compliance with modern safety standards.
