The Pilz PNOZ X3 48VAC 24VDC 3N/O 1N/C 1SO – 774312 is a high-performance safety relay engineered to safeguard machinery and operators by reliably monitoring emergency stop devices, safety gates, and protective systems. Belonging to the trusted PNOZ X series, it delivers robust safety functionality, dual supply flexibility, and compliance with international standards.

This model is designed for dual supply operation, using a 48 V AC primary supply alongside a 24 V DC secondary voltage. This combination provides exceptional integration flexibility, making it suitable for a wide range of industrial environments where mixed-voltage control systems are in place. It reduces the need for additional conversion equipment, saving space and simplifying both new installations and retrofit projects.

The relay is equipped with a comprehensive output set, including three normally open (N/O) safety contacts, one normally closed (N/C) contact, and one signalling output (SO). The N/O contacts provide reliable enabling for actuators, motors, or contactors, ensuring hazardous operations are safely stopped in an emergency. The N/C contact is ideal for feedback circuits or additional monitoring functions, while the SO provides clear operational status signals to higher-level controllers. This combination makes the relay especially valuable in systems requiring both reliable shutdown and diagnostic capability.

To further strengthen system safety, the PNOZ X3 supports dual-channel monitoring with two safety inputs. This configuration ensures redundancy and allows for detection of wiring faults, shorts, or contact failures, helping maintain high safety integrity. Such functionality is essential when monitoring devices like emergency stop buttons, protective doors, or light curtains.

With a power consumption of only 5 VA under AC supply, the relay delivers reliable performance while keeping energy demand low. Its compact form factor makes it ideal for control cabinets where space efficiency is important, and its rugged build ensures long service life under frequent actuation and continuous use.

The PNOZ X3 48VAC 24VDC is suitable for use across industries such as packaging, manufacturing, material handling, robotics, and processing. By ensuring machinery is immediately brought to a safe state when triggered, it protects operators, equipment, and production uptime.

In summary, the Pilz PNOZ X3 48VAC 24VDC 3N/O 1N/C 1SO – 774312 offers a powerful blend of flexible dual supply compatibility, versatile output configuration, and dependable dual-channel safety monitoring. Compact, energy-efficient, and standards-compliant, it provides a reliable solution for safeguarding industrial machinery and ensuring operator protection.
