PILZ PNOZ X2.1 24VAC/DC-2N/0 1N/C SAFETY RELAY 774306

The Pilz PNOZ X2.1 24VAC/DC-2N/0 1N/C Safety Relay (part number 774306) is a safety relay designed for use in industrial applications to monitor and control safety functions in machinery and systems. Safety relays are vital components in safety circuits, ensuring that machines operate within safe parameters and that hazards are minimized, especially in compliance with safety standards such as ISO 13849-1 and IEC 61508.

Key Features and Specifications:

1. Function:

   • The Pilz PNOZ X2.1 is part of the PNOZ series, which are modular safety relays used for monitoring and ensuring safe operation of machines and systems. It is designed to meet the needs of machine safety by monitoring emergency stop circuits, safety doors, light barriers, or other safety-related functions.
   • It features two safety relay contacts (2 N/O – Normally Open) and one auxiliary contact (1 N/C – Normally Closed), enabling it to implement safety control, shutdown, or fault detection logic for machines.

2. Voltage Rating:

   • 24 VAC/DC: The relay operates with an input voltage of 24V AC/DC, making it suitable for a wide range of industrial control systems, which commonly operate at this voltage.

3. Contact Configuration:

   • 2N/0 (2 Normally Open Contacts / 0 Normally Closed): This means the relay has two normally open (N/O) contacts, which are used to control outputs in a safe state when the relay is active, and no normally closed (N/C) contacts, which would typically be used for fault detection or control in specific applications.
   • 1N/C (1 Normally Closed Contact): A single normally closed (N/C) contact is provided, which can be used in safety circuits to indicate a failure or fault condition when the contact is open.

4. Safety Applications:

   • The relay is designed for safety-related control circuits in industrial machines and automation systems.
   • It ensures that if a safety condition (such as an emergency stop or a fault) occurs, it will safely interrupt the control system and disable the operation of machinery, thus preventing injuries or equipment damage.

5. Compliance:

   • The PNOZ X2.1 safety relay complies with safety standards like ISO 13849-1, ensuring that the safety system operates with the required reliability and risk reduction.
   • It may also meet other relevant industry standards (e.g., IEC 61508), ensuring it can be integrated into safety-critical systems where a failure would result in hazardous conditions.

6. Diagnostic Features:

   • The PNOZ X2.1 relay offers diagnostic features that help operators and maintenance teams monitor the health of the safety circuit. It includes LED indicators that show the status of the relay (active, fault, etc.), providing visual feedback for troubleshooting.

7. Applications:

   • Emergency Stop Circuits: Ensures that an emergency stop button or safety switch disconnects the power and halts operation safely.
   • Guarding Systems: Can be used to monitor safety doors, light curtains, or other guarding devices to prevent accidental access to hazardous areas.
   • Machine Safety Interlocks: Ideal for systems where access to dangerous machinery must be restricted when certain conditions are met.
   • Fault Monitoring: Can be integrated into fault detection circuits, ensuring that any fault is immediately recognized, and machinery is safely shut down.

Benefits of the Pilz PNOZ X2.1:

• High Safety Standards: The PNOZ series relays meet high safety performance requirements, making them ideal for machinery that needs to comply with global safety regulations.
• Simple Integration: Its compact design and wide voltage range make it easy to integrate into existing control systems.
• Reliable and Durable: The relay provides long-lasting performance, with features designed to withstand harsh industrial environments.
• Clear Diagnostics: Diagnostic LEDs help with troubleshooting, reducing downtime and simplifying maintenance tasks.

Conclusion:

The Pilz PNOZ X2.1 24VAC/DC-2N/0 1N/C Safety Relay (774306) is a versatile and reliable component for ensuring the safety of industrial systems. It is ideal for applications that require strict monitoring of safety functions like emergency stops, light curtains, or safety doors. With its robust design, diagnostic features, and compliance with international safety standards, this relay plays a crucial role in reducing risks and ensuring the safe operation of machinery in industrial environments.
