The Pilz PNOZ X3 is a compact, versatile safety relay designed for monitoring safety functions in a wide range of industrial machinery and automation applications. Known for its reliability and ease of use, it serves as a fundamental building block for safety circuits, ensuring the protection of personnel and equipment.
This specific model (PNOZ X3 24VAC/24VDC) is distinguished by its flexible power supply range, making it suitable for various control cabinet environments.
Key Features and Benefits
-
Universal Power Supply: Operates on both 24V AC and 24V DC, providing exceptional flexibility for integration into different electrical systems without needing a specific power supply unit.
-
Robust Safety Outputs: Features 3 Safety Normally Open (NO) Contacts and 1 Safety Normally Closed (NC) Contact. These forcibly guided contacts (mechanically linked) are fault-proof and are used to control the main safety circuit (e.g., contactor coils).
-
Auxiliary Signal Output (SO): Includes 1 Auxiliary Normally Open (NO) Contact for non-safety-related functions, such as signaling the status of the safety circuit to a PLC or indicator lamp.
-
Compact Design: Saves valuable space in the control cabinet, allowing for efficient panel layout.
-
Easy Installation and Wiring: Features a clear labeling and a direct wiring method with screw terminals, simplifying setup and reducing installation time.
-
High Reliability: From Pilz, a world-leading brand in safety automation, ensuring high quality and compliance with international safety standards.

What is a Safety Relay?
A safety relay is a specialized component that monitors safety devices like emergency stops or guard doors. Its core function is to ensure that when a fault is detected (e.g., a welded contactor or a broken wire), the system defaults to a safe state by shutting down the hazardous process. The PNOZ X3 performs this critical function with high integrity.
Common Applications
The Pilz PZNOZ X3 is ideal for implementing safety functions in:
-
Packaging Machines
-
Presses and Metalforming Machinery
-
Robotic Cells
-
Assembly and Automation Lines
-
Conveyor Systems
