The Pilz PNOZ S2 24VDC 3 N/O 1 N/C (part no. 750102) is a versatile and compact safety relay designed to provide reliable monitoring of safety functions such as emergency stops, safety gates, and other protective devices in industrial environments. Belonging to the PNOZsigma series, it combines space-saving design, energy efficiency, and proven reliability to meet the requirements of modern safety applications.

Operating at a 24 V DC supply voltage, the PNOZ S2 integrates seamlessly into widely used low-voltage industrial control networks. Its low power consumption of only 2 W makes it highly efficient, supporting energy-conscious operations without sacrificing performance.

The relay is equipped with 3 normally open (N/O) safety contacts and 1 normally closed (N/C) contact, enabling flexible integration into a variety of safety circuits. The N/O contacts are used to interrupt dangerous machine functions, while the N/C contact is typically used for diagnostics or auxiliary signalling, helping operators monitor system status in real time. This configuration ensures both safety functionality and efficient process control.

In addition, the device features a semiconductor output, providing non-wearing, reliable status signalling. This digital output is particularly useful for integration into monitoring or automation systems, offering engineers a clear and dependable method of communicating the relay’s switching status without mechanical wear.

With one input channel, the PNOZ S2 is simple to configure, making it an excellent choice for straightforward safety applications. Despite its simplicity, it delivers robust monitoring performance, consistent with Pilz’s long-standing reputation as a leader in machine safety. The design also allows for space-efficient installation, a hallmark of the PNOZsigma series, which provides maximum functionality in minimal width.

The PNOZ S2 safety relay is widely used across industries such as automotive, packaging, material handling, food and beverage, and robotics. Its compact size and reliable performance make it particularly suitable for smaller to mid-sized machines or applications where control cabinet space is at a premium.

Compliance with relevant safety standards, including EN 60947-4-1 and functional safety regulations, ensures that the PNOZ S2 not only provides effective protection but also supports regulatory compliance. By halting dangerous movements in milliseconds when triggered by a connected emergency stop or protective device, it plays a critical role in protecting both operators and equipment.

In summary, the Pilz PNOZ S2 24VDC 3 N/O 1 N/C is a highly reliable and compact safety relay, offering 3 safety contacts, 1 auxiliary contact, a semiconductor output, and low power consumption. With its combination of energy efficiency, space-saving design, and dependable safety performance, it is an ideal choice for modern industrial safety systems requiring both protection and operational efficiency.
