The Pilz PNOZ m B1 is a base unit within the PNOZmulti 2 family of small controllers, designed for configurable and modular safety applications. It provides a centralised, flexible solution for implementing safety and standard control functions in machinery and plant automation. Compact yet powerful, the PNOZ m B1 delivers both reliability and scalability, ensuring compliance with international safety standards while supporting efficient operation.

Powered by a 24 V DC supply, the unit consumes 18.5 W, making it energy-efficient for continuous operation in modern control environments. Its design focuses on balancing compactness with high performance, allowing engineers to implement multiple safety functions within a single controller while keeping overall system energy requirements low.

The PNOZ m B1 is equipped with four test pulse outputs, a key feature that enables fault detection in connected sensors and actuators. These test pulses ensure that short circuits, cross-circuits, or wiring faults are identified quickly, improving diagnostic coverage and enhancing overall system safety. This makes the controller especially effective in applications requiring a high degree of functional safety, including emergency stop circuits, safety gates, light curtains, and enabling switches.

A distinctive feature of the PNOZ m B1 is its integrated Ethernet communication interface, which comes with a factory-set IP address (169.254.60.1). This interface allows for diagnostics, parameterisation, and communication with higher-level controllers or HMIs. The Ethernet connectivity ensures that safety data can be accessed in real time, making it easier to monitor system performance, troubleshoot faults, and maintain compliance with Industry 4.0 and smart factory requirements.

As a modular base unit, the PNOZ m B1 supports expansion with Pilz input/output modules, motion monitoring units, and communication modules. This scalability ensures the safety controller can grow with the machine’s complexity, from standalone equipment to fully integrated production lines. Configuration is carried out using the intuitive PNOZmulti Configurator software, where safety functions are implemented via a graphical, drag-and-drop interface rather than traditional programming. This saves engineering time, reduces errors, and simplifies adjustments throughout the machine’s lifecycle.

The compact design of the PNOZ m B1 supports DIN-rail mounting, saving valuable cabinet space while maintaining ease of installation and wiring. Its robust build ensures long-term reliability, even in demanding environments such as automotive production, packaging, robotics, and process automation.

In summary, the Pilz PNOZ m B1 is a powerful, scalable, and Ethernet-enabled base unit for the PNOZmulti 2 system. With its 24 V DC supply, four test pulse outputs, modular expansion capability, and integrated Ethernet diagnostics, it delivers a reliable foundation for advanced safety and automation applications in modern industry.
