The Pilz PNOZ m B0 is the core base unit of the PNOZmulti 2 modular safety controller system, designed to deliver highly configurable and scalable safety solutions for modern machine and plant automation. Acting as the central processing and control hub, the PNOZ m B0 enables engineers to implement multiple safety functions in a single, compact device, reducing complexity while ensuring compliance with stringent international safety standards.

Operating on a 24 V DC system supply (U1), the PNOZ m B0 is engineered for reliable low-voltage integration into industrial environments. It is safeguarded by a 6 A automatic circuit breaker (characteristic B), which provides robust protection against overloads and ensures system stability even under demanding conditions. In addition, the unit features a dedicated U2 supply for semiconductor (SC) outputs, which separates power for outputs from the main system supply. This separation enhances reliability and allows for safe and efficient management of output devices such as contactors, actuators, and drives.

The strength of the PNOZ m B0 lies in its modular flexibility. As a base unit, it can be expanded with a wide range of Pilz input/output modules, motion monitoring units, and communication modules, allowing tailored solutions for specific applications. This modularity supports everything from simple machine safeguarding to complex, distributed safety architectures across production lines. Configuration is performed using the PNOZmulti Configurator software, a user-friendly graphical tool that allows engineers to drag and drop function blocks, design logic circuits, and assign safety functions without complex programming.

In terms of performance, the PNOZ m B0 is capable of monitoring a broad spectrum of safety devices, including emergency stop buttons, safety gates, light curtains, and two-hand control systems. By consolidating multiple safety functions into a single programmable system, it reduces the need for separate relays, simplifies wiring, and frees up space within control cabinets.

Built with Pilz’s renowned reliability, the PNOZ m B0 delivers consistent operation across varied industrial sectors such as automotive, packaging, robotics, and process automation. Its compact housing is optimised for DIN-rail mounting, saving space and supporting easy installation. With clearly marked terminals and structured wiring, commissioning is efficient and minimises the risk of setup errors.

In summary, the Pilz PNOZ m B0 is the foundation of the PNOZmulti 2 platform, offering configurable safety control with a secure 24 V DC supply, modular expandability, and dedicated support for semiconductor outputs. By combining flexibility, simplicity, and reliability, it ensures both operators and machinery are protected while enabling scalable, future-proof safety architectures tailored to evolving production needs.
