The Pilz PNOZ 16 230VAC 24VDC 2N/O (Part No. 774066) is a high-performance safety relay from the trusted PNOZ series, engineered to provide reliable monitoring and control of safety functions in industrial automation environments. With its dual-voltage design and robust safety performance, it offers an effective solution for protecting both personnel and equipment in compliance with international safety requirements.

A defining feature of this relay is its ability to operate with two supply voltages: a 230 V AC input for the main control circuit and a 24 V DC auxiliary supply. This dual-voltage capability allows it to integrate easily into systems where both AC and DC supplies are present, making it suitable for modern automation environments that often combine different power sources. The efficient design ensures a low AC power consumption of just 3.5 VA, reducing energy costs and enabling continuous duty operation without excessive load on the power system.

The relay provides two normally open (N/O) safety contacts, which can be used for direct control of actuators such as motors, contactors, or valves. These outputs ensure safe disconnection of hazardous machine functions when triggered by protective devices such as emergency stop buttons, safety gates, or enabling switches. By reliably switching off dangerous energy sources, the PNOZ 16 minimises risk to operators while maintaining machine integrity.

Like all relays in the PNOZ series, the PNOZ 16 is engineered to meet stringent international safety standards. It is designed for use in applications requiring high levels of reliability, supporting Performance Level e (EN ISO 13849-1) and SIL compliance (IEC 62061) when integrated into appropriately designed safety circuits. This ensures that machine builders and plant operators can meet regulatory and legal obligations while achieving a safe working environment.

The compact and durable design of the PNOZ 16 also ensures straightforward installation in control cabinets, even where space is limited. Clear wiring terminals and labelling simplify integration, reducing commissioning time and minimising wiring errors. The relay’s robust build is engineered for long service life, making it a cost-effective investment by reducing the need for frequent maintenance or replacement.

This model is particularly well-suited for industries such as manufacturing, packaging, material handling, and process engineering, where reliable emergency stop and safety monitoring are critical. Its dual supply design provides greater flexibility for integration into diverse systems, ensuring that both traditional and modern automation setups can benefit from its safety functions.

In summary, the Pilz PNOZ 16 230VAC 24VDC 2N/O combines dual supply flexibility, low energy consumption, reliable outputs, and compliance with safety standards. As part of Pilz’s renowned PNOZ family, it offers a dependable solution for safeguarding machinery and protecting operators across a wide range of industrial applications.
