The Pilz PNOZ X10 230–240VAC 6N/O 4N/C 3LED, part number 774706, is a high-capacity safety relay designed to provide reliable monitoring and switching of safety functions in industrial environments. As part of the well-established PNOZ X series, this relay combines multiple safety outputs, built-in diagnostics, and robust performance, making it a dependable solution for safeguarding machinery and protecting personnel.

Operating on a 230–240 V AC supply, the PNOZ X10 is engineered for use in standard industrial power systems. It provides a strong switching capacity of 240 V AC at 8 A and 24 V DC at 8 A, ensuring it can effectively control both alternating and direct current safety circuits. This flexibility allows it to be integrated across a wide range of applications without the need for additional relay types.

A standout feature of the relay is its extensive contact configuration, offering 6 normally open (N/O) safety contacts and 4 normally closed (N/C) auxiliary contacts. The six N/O contacts provide reliable disconnection of hazardous energy sources, making the device suitable for large or complex machines where multiple actuators, motors, or circuits must be controlled simultaneously. The four N/C auxiliary contacts supply valuable system feedback, enabling monitoring and diagnostics through higher-level controllers or operator panels. This dual functionality ensures both robust safety protection and transparency of system conditions.

The PNOZ X10 also incorporates 3 integrated LED indicators, providing clear and immediate information about relay status. The LEDs monitor key conditions such as power availability, input channel function, and potential faults. This real-time diagnostic capability allows operators and maintenance staff to quickly identify issues, reducing downtime and ensuring continued safe operation.

Typical applications for the PNOZ X10 include monitoring devices such as emergency stop pushbuttons, safety gates, light curtains, and two-hand controls. When triggered, the relay guarantees fast and reliable disconnection of hazardous machine movements, ensuring compliance with safety standards and protecting operators from injury.

Built to meet EN 60947-4-1 utilisation categories, the relay is certified to perform reliably under demanding conditions. Its high-quality electromechanical design ensures consistent performance, long service life, and low maintenance requirements, even in environments where frequent switching cycles are necessary.

The PNOZ X10 is particularly valuable in industries such as manufacturing, packaging, robotics, and process automation, where large systems with multiple safety requirements must be managed efficiently. Its high number of contacts and built-in LED diagnostics make it ideal for ensuring both comprehensive machine safety and ease of maintenance.

In summary, the Pilz PNOZ X10 230–240VAC 6N/O 4N/C 3LED (774706) is a powerful safety relay offering high output capacity, integrated diagnostics, and compliance with international standards. With its extensive contact configuration, wide voltage compatibility, and LED feedback, it provides a reliable, practical, and efficient solution for safeguarding personnel and machinery in complex industrial applications.
