The Pilz PNOZ S9 24VDC 3 N/O T 1 N/C T (part no. 750109) is a robust and versatile safety relay designed to provide reliable monitoring of safety functions in automated machinery and industrial processes. As part of the PNOZsigma range, this device offers a combination of compact design, energy efficiency, and flexible contact arrangements, making it an excellent choice for safeguarding both personnel and equipment.

Operating with a 24 V DC supply voltage, the PNOZ S9 integrates seamlessly into widely used low-voltage systems. Its efficient design requires just 2 W of power, ensuring minimal energy consumption while reducing heat buildup in control cabinets. This not only contributes to energy savings but also supports long-term system reliability by minimising stress on electrical components.

The relay provides a contact configuration of 3 normally open (N/O) safety contacts and 1 normally closed (N/C) auxiliary contact. This flexible arrangement makes it suitable for a wide variety of safety functions, including emergency stop monitoring, safety gate control, and other protective device integration. The N/O contacts provide safe enabling paths for machine operation when all safety conditions are met, while the N/C auxiliary contact offers valuable diagnostic or feedback capability to the control system.

Designed in line with EN 60947-4-1 utilisation category requirements, the PNOZ S9 guarantees reliable performance across both AC and DC load switching. This compliance ensures that the device can be deployed with confidence in safety-critical applications where consistency and dependability are essential.

The PNOZsigma series is well known for its space-saving modular design, and the PNOZ S9 continues this tradition. Its compact format allows engineers to maximise control cabinet space, while its straightforward wiring and configuration options simplify installation and reduce commissioning time. These features make it a cost-effective solution for both new projects and system retrofits.

The relay is widely used across industries such as automotive, packaging, robotics, material handling, and general machinery manufacturing. In each of these applications, it plays a crucial role in ensuring machinery stops immediately when hazardous conditions are detected, protecting operators and preventing equipment damage.

In summary, the Pilz PNOZ S9 24VDC 3 N/O T 1 N/C T is a highly reliable and energy-efficient safety relay that combines flexibility, compliance, and ease of integration. With its 24 V DC supply operation, versatile contact configuration, low power consumption, and EN 60947-4-1 certification, it delivers dependable performance for safeguarding people and processes in demanding industrial environments.
