The Pilz PNOZ 16SP 24VAC 24VDC 2N/O (Part Number: 777070) is a safety relay designed for the reliable monitoring of safety devices, with particular suitability for safety mats and related protective equipment. As part of Pilz’s PNOZ family—renowned globally for its quality and dependability—the PNOZ 16SP combines robust design, flexibility, and compliance with international safety standards, ensuring maximum protection for both operators and machinery.

A key feature of the PNOZ 16SP is its ability to monitor safety mats with a resistance specification of 80 Ω, making it highly effective in safeguarding floor-level operator access areas around hazardous machinery. When integrated into a safety circuit, the relay ensures that machinery stops immediately if a mat is stepped on, preventing accidents and enabling compliance with machine safety regulations.

The relay operates on a 24 V AC or 24 V DC supply, offering flexible installation options to accommodate different control system designs. Its ability to handle both AC and DC input voltages makes it suitable for a wide range of environments and simplifies integration into existing systems.

Equipped with two normally open (N/O) safety contacts, the PNOZ 16SP can reliably switch safety-critical loads such as contactors or actuators, ensuring immediate interruption of hazardous machine functions. In addition, the inclusion of two semiconductor outputs supports diagnostic functions and communication with higher-level control systems. This combination provides not only effective machine shutdown but also improved visibility into system status, enabling faster troubleshooting and reducing downtime.

With dual input channels, the relay supports redundancy and cross-monitoring, which are essential in safety-critical applications. This ensures that faults or manipulation attempts are detected and that the safety function remains dependable under all conditions.

The PNOZ 16SP is also compliant with EN 60947-1 utilisation category DC-12, underscoring its adherence to international electrical and safety standards. This guarantees reliable performance across a broad range of operating conditions, contributing to both safety compliance and long service life.

Built with the robustness typical of Pilz products, the PNOZ 16SP is suitable for use in industries such as manufacturing, packaging, logistics, and materials handling, where safety mats and similar protective devices are widely applied. Its compact, durable design ensures ease of integration into control cabinets while delivering consistent, high-reliability safety performance.

In summary, the Pilz PNOZ 16SP 24VAC 24VDC 2N/O (777070) is a versatile and dependable safety relay designed to monitor safety mats and other protective devices. With its flexible supply options, dual inputs, semiconductor outputs, and compliance with EN standards, it provides a reliable foundation for protecting operators and machinery in demanding industrial environments.
