The Pilz PNOZ 16 110VAC 24VDC 2N/O (Part No. 774063) is a versatile safety relay from the trusted PNOZ family, designed to ensure reliable monitoring of safety functions in industrial automation. Combining dual voltage operation with proven safety technology, this relay provides dependable protection for operators and machinery while maintaining compliance with international safety requirements.

One of the standout features of this unit is its dual supply design. The relay operates with a primary supply of 110 V AC, commonly used in industrial environments, and incorporates a 24 V DC auxiliary supply. This flexibility allows the relay to interface easily with mixed-voltage control systems, making it particularly valuable in applications where both AC mains and low-voltage DC control circuits are present.

The low power consumption of just 3.5 VA on the AC side ensures that the relay is energy-efficient, even in continuous operation. This efficiency not only reduces operating costs but also minimises thermal load in control panels, helping maintain stable system performance.

The relay provides two normally open (N/O) safety contacts, enabling direct switching of actuators such as motors, drives, valves, or contactors. These outputs are designed to disconnect hazardous energy sources reliably when triggered by safety devices such as emergency stop buttons, guard switches, or enabling switches. By ensuring immediate shutdown in unsafe conditions, the relay delivers dependable protection against accidents and equipment damage.

As part of the PNOZ series, the PNOZ 16 110VAC 24VDC 2N/O is engineered to comply with stringent international safety standards such as EN ISO 13849-1 (up to Performance Level e) and IEC 62061 (SIL CL). This ensures that it can be integrated into safety systems with the highest integrity levels, providing both functional safety and regulatory compliance.

The relay’s compact design and clear wiring layout make installation straightforward, reducing commissioning time and wiring errors. Its robust build ensures a long operational life, even in demanding industrial environments, lowering maintenance requirements and contributing to reduced system downtime.

The PNOZ 16 is ideally suited for applications across industries such as manufacturing, packaging, robotics, material handling, and process automation, where reliable emergency stop and safety device monitoring are essential. By offering dual-voltage capability, the relay provides the versatility needed to adapt to a variety of system architectures while maintaining consistent performance.

In summary, the Pilz PNOZ 16 110VAC 24VDC 2N/O combines dual supply flexibility, low energy consumption, robust safety contacts, and compliance with global safety standards. It is a reliable and efficient safety relay that plays a crucial role in protecting both personnel and machinery, making it an essential component of modern industrial safety systems.
