- Comprehensive Output Options: Provides 3 normally open (N/O) safety contacts, 1 normally closed (N/C) contact, and 1 semiconductor output (SO) for versatile control and monitoring.
- Dual-Channel Monitoring: Features 2 safety inputs for redundant and fault-tolerant monitoring of emergency stop devices, guard doors, and enabling switches.
- Energy-Efficient Performance: Consumes only 5 VA on the AC supply, optimised for continuous and reliable industrial operation.
The Pilz PNOZ X3 240VAC 24VDC 3N/O 1N/C 1SO (Part No. 774319) is a high-performance safety relay from the Pilz PNOZ X series, engineered to provide dependable monitoring of essential safety functions such as emergency stop buttons, guard doors, and enabling devices. With its robust electrical design, flexible outputs, and dual-voltage capability, it is an essential solution for safeguarding both operators and machinery in industrial automation environments.
This model is designed to work with a 240 V AC supply voltage as the main input, combined with an auxiliary 24 V DC supply. This dual supply setup makes the relay adaptable for integration into diverse control architectures, supporting traditional AC power infrastructures while providing compatibility with modern low-voltage DC control systems. Its low power consumption of just 5 VA ensures reliable performance with energy efficiency, even under continuous operation.
One of the standout advantages of the PNOZ X3 is its flexible contact configuration. The relay includes 3 normally open (N/O) safety contacts for disconnecting actuators such as motors, valves, or drives, ensuring safe shutdown of hazardous machine functions. It also offers 1 normally closed (N/C) contact, which is ideal for signalling and feedback purposes, and 1 semiconductor output (SO) that provides reliable electronic signalling to higher-level controllers or monitoring systems. This combination of contacts allows system designers to implement both direct safety switching and comprehensive diagnostics.
Equipped with 2 safety inputs, the PNOZ X3 supports dual-channel monitoring for redundancy and fault detection. This ensures that potential failures, such as wiring errors or short circuits, are quickly detected and acted upon. Dual-channel input capability is essential for achieving compliance with international safety standards and for maintaining high safety integrity in demanding applications.
The relay is designed to meet global requirements for safety performance and compliance, supporting integration into systems conforming to EN ISO 13849-1 (Performance Level e) and IEC 62061 (SIL CL 3). This guarantees that the PNOZ X3 not only provides reliable protection but also meets the legal and operational obligations of machine builders and plant operators.
The rugged and compact design of the PNOZ X3 ensures long service life even in harsh industrial conditions. With clearly marked terminals and a straightforward layout, installation and wiring are simplified, reducing commissioning time and minimising errors during setup.
The PNOZ X3 240VAC 24VDC 3N/O 1N/C 1SO is ideal for industries such as manufacturing, packaging, robotics, process control, and material handling, where dependable safety monitoring is critical. Its combination of versatile outputs, dual supply compatibility, and standards-compliant safety monitoring makes it an adaptable and reliable solution for safeguarding industrial operations.
In summary, the Pilz PNOZ X3 240VAC 24VDC combines energy efficiency, flexible output configurations, dual-channel safety monitoring, and international compliance. It is a robust and future-proof safety relay that enhances both operator protection and machine productivity in demanding automation environments.
