The Pilz PNOZ s7 C 24VDC 4N/O 1N/C is a compact and efficient safety relay from the Pilz PNOZsigma range, designed to reliably monitor safety functions in industrial environments. Offering a combination of low energy consumption, flexible output options, and compliance with international safety standards, it provides an essential layer of protection for both personnel and machinery.

The relay is designed for operation on a 24 V DC supply, with a low power consumption of only 2 W. This makes it highly energy-efficient and ideal for applications requiring continuous monitoring without adding unnecessary load to the control system. The DC design ensures compatibility with modern low-voltage automation and safety architectures.

Equipped with one safety input channel, the PNOZ s7 C is particularly suitable for straightforward safety functions, such as monitoring an emergency stop device, guard switch, or enabling control. This simplicity makes it a practical choice for systems that require reliable, single-channel safety monitoring without the complexity of larger multi-input relays.

One of the key strengths of the PNOZ s7 C lies in its output configuration. It provides four normally open (N/O) safety contacts, which can be used to directly disconnect actuators such as motors, drives, or valves, ensuring immediate shutdown of hazardous energy sources when necessary. Additionally, the relay includes one normally closed (N/C) contact, which can be used for signalling, status feedback, or monitoring functions. This flexibility supports robust and adaptable safety circuit design.

The relay is manufactured in compliance with EN 60947-4-1 utilisation categories (AC/DC1), ensuring reliable performance under industrial switching conditions. This compliance guarantees safe operation in demanding environments, supporting both functional safety and regulatory conformity.

Compact and easy to install, the PNOZ s7 C is part of the PNOZsigma series, known for its space-saving design and simplified wiring. Its clear terminal layout reduces commissioning time, minimises installation errors, and makes it straightforward to integrate into existing control systems. Once installed, the unit’s rugged construction ensures a long service life with minimal maintenance requirements.

Applications for the PNOZ s7 C span a wide range of industries, including manufacturing, packaging, logistics, robotics, and process automation, where safety relays are critical for monitoring emergency stops and protective devices. The relay is especially useful in smaller systems or machines where a compact, single-input safety relay is sufficient but where multiple outputs are needed for effective control and feedback.

In summary, the Pilz PNOZ s7 C 24VDC 4N/O 1N/C combines energy-efficient DC operation, versatile contact outputs, straightforward input monitoring, and compliance with international safety standards. It is a practical and dependable solution for ensuring machine safety, protecting operators, and maintaining productivity in modern industrial environments.
