Pilz Expands myPNOZ Safety Relay with Versatile Modules for Smarter, Safer Automation

In modern manufacturing, safety systems are being pushed to their limits. As machines become faster and more complex, the need for flexible, reliable safety solutions is more urgent than ever. Conventional setups, often rigid and difficult to scale, struggle to adapt to evolving production requirements, causing downtime, increasing costs, and leaving safety gaps that can’t be ignored. Pilz is addressing these challenges head-on with an expanded range of modules for its modular safety relay system, myPNOZ. With five new components, four input modules, and one output, now available via the myPNOZ Creator online tool, users can configure systems that are as specific and scalable as their production demands. From advanced gate monitoring to intelligent output control, these modules deliver enhanced safety and smoother operations with fewer hardware complications.

Monitoring Access Points with Greater Precision

One of the standout additions is Pilz’s focus on securing machine access points like gates and light curtains. The new PNOZ yi7 input module handles both monitoring and control of safety guard locking systems. It ensures machines stay stopped as long as a gate is open, a critical function in safeguarding workers during maintenance or loading tasks. When paired with Pilz’s own locking devices, PSENmlock and PSENslock, the system becomes a complete safety gate solution.

The PNOZ yi8 module goes a step further by supporting both traditional safety switches, like the PSENmag, and electrosensitive protective equipment (ESPE), such as safety light barriers. It offers a simple way to integrate multiple safety devices through one module, saving time on wiring and programming while expanding safety coverage.

More Inputs, Fewer Modules

Space and efficiency matter just as much as functionality in industrial settings. Pilz recognizes this with the new yi5 input module, which has four safe 2-channel inputs in a single unit. That means fewer modules are needed for systems with numerous safety functions. In practice, users can now implement up to 30 individual safety inputs on a single myPNOZ relay. The result? Less hardware, lower costs, and more room in already crowded control cabinets.

Adapting to Multiple Safety Modes

The new PNOZ yi6 module introduces even more flexibility with “Group OR” safety logic. This allows different input devices to function as alternatives depending on the machine’s operating mode. For example, in automatic mode, safety may rely on a gate sensor and a light curtain. But in manual mode, the same system might switch over to a two-hand control button. With the Yi6, both configurations can be managed using just one module, simplifying the setup while maintaining strict safety compliance.

It’s not just about inputs; Pilz has also enhanced output capabilities. The new PNOZ yo5 output module includes four outputs, two of which support delay-on or delay-off functions. Combined with two direct outputs, it provides more control over timing and response without needing extra hardware. This reduces component count and helps engineers fine-tune how machines react in safety-critical scenarios, like emergency stops or power-down sequences.

Building Custom Systems with myPNOZ Creator

All of these new modules are available through the myPNOZ Creator, Pilz’s online configuration tool that simplifies the design and ordering process. Users can build their own custom-made safety systems with a few clicks, receiving pre-assembled, pre-tested units that are ready to install. Each module connects through BUS connectors and draws power from a central head unit, making expansion or modification straightforward as needs change.

As automation grows more demanding, manufacturers need smarter safety systems that can adapt without added complexity. With these new myPNOZ modules, Pilz delivers exactly that: compact, customizable components that secure access points, simplify system design, and reduce hardware overhead. It’s an approach to safety that meets today’s challenges while laying a foundation for tomorrow’s innovation.
