The Pilz PNOZ 16S 24VAC 24VDC 2N/O 2SO (Part Number: 774070) is a reliable and versatile safety relay designed for monitoring safety functions and providing immediate, fail-safe responses to hazardous conditions. As part of the globally trusted PNOZ safety relay family, the 16S ensures operators and machinery remain protected while simplifying system integration.
This model offers dual supply flexibility, operating with either 24 V AC or 24 V DC, making it highly adaptable across diverse industrial applications. Whether used in facilities with traditional AC wiring or in modern DC-based control architectures, the PNOZ 16S integrates seamlessly, reducing the need to stock multiple relay variants for different environments.
The output configuration includes two normally open (N/O) contacts and two semiconductor outputs (SO). The N/O contacts provide reliable electromechanical switching, capable of disconnecting hazardous energy sources in an emergency, while the semiconductor outputs enable rapid, wear-free switching ideal for signalling, diagnostics, or controlling high-frequency processes. This combination of output types gives the device a unique advantage, ensuring both robustness and responsiveness in safety-critical systems.
With a power consumption of just 3.5 VA (AC), the PNOZ 16S is energy efficient without compromising reliability. Its design supports continuous operation in industrial environments where long-term durability, low maintenance, and consistent safety performance are essential.
As with all Pilz safety relays, the PNOZ 16S complies with international safety standards, ensuring safe integration into systems requiring adherence to EN ISO 13849-1 and EN 62061 for functional safety. It is suitable for monitoring devices such as emergency stop buttons, safety gates, two-hand control panels, or pressure-sensitive mats, making it an essential component in comprehensive machine safeguarding strategies.
The robust industrial design of the PNOZ 16S makes it ideal for use in demanding sectors such as automotive production, packaging, material handling, food and beverage, and process automation. Its proven reliability reduces downtime and supports continuous, safe operations.
In summary, the Pilz PNOZ 16S 24VAC 24VDC 2N/O 2SO (774070) is a versatile, energy-efficient, and highly dependable safety relay. With its dual supply voltage flexibility, mixed mechanical and semiconductor outputs, low power consumption, and compliance with global safety standards, it delivers a robust solution for safeguarding both people and machines in modern automation environments.
