must be inserted. Alongside the documentation, users also receive a wiring diagram and can order their myPNOZ in the desired configuration almost at the touch of a button. myPNOZ is then delivered pre- configured and ready to install. For users that just means wiring and, thanks to the safety matrix that’s also included, simple and fast commissioning. The type code is printed on the device, so if necessary myPNOZ can be re-ordered at any time in this exact configuration. So myPNOZ is much more than a “classic” safety relay? Florian Rotzinger: We have combined proven concepts with some innovative features: myPNOZ is the result of safety expertise gathered over decades. We have taken and then optimised the proven features of our PNOZ safety relays, such as reliability, simplicity, ease of operation during installation and maintenance, and diagnostics. On the hardware side myPNOZ consists of a head module with plug-in expansion modules. The head module provides the voltage supply as well as a higher-level safety function. How about the expansion modules? Are they looking more traditional or are they also innovative? Florian Rotzinger: We offer a total of 12 expansion modules: four input modules with two safe input functions per input module, four output modules and four input/output modules. The output modules are available with relay or semiconductor outputs and an optional time delay, if that's what customers need. The whole structure enables customer-specific applications Keyword: individualisation. Who in particular did Pilz have in mind with a view to its application? Harald Wessels: The focus is quite generally on automation within mechanical engineering, where the safety relay can be used in a wide range of industries. Such as woodworking for example. Anyone wishing to implement safety applications of simple to average complexity will benefit in particular from myPNOZ. The same is true if you wish to cover two to 16 safe safety functions without using engineering software. The individual “pay-what-you- need” approach of myPNOZ guarantees an optimum cost-benefit ratio and makes the safety relay an attractive solution when you compare it with conventional safety relays and other products on offer on the market. Which to use…myPNOZ or“just”PNOZ? The following rule of thumb applies: One or two safety functions, such as E-STOP and safety gate for example, can still be covered well and cost-effectively in future using a classic safety relay. However, myPNOZ should definitely be considered as an efficient and viable alternative when there are between two and sixteenmonitored safety functions. Comparedwith conventional relays, myPNOZ is themore flexible and expandable product in this segment. A comparison between myPNOZ and PNOZsigma is recommended even from two safety functions. In the case of a simple press retrofit where an E-STOP and safety gate need securing, a classic PNOZ safety relay would be sufficient at first glance. However, if you add a light curtain or if the safety concept is to take different zones into account, thenmyPNOZ is recommended. It’s a similar situation for plants with two zones, which the operator wants to handle differently in terms of safety technology. Ultimately, an economical safety solution should not stop the entire plant in an emergency, but just one part of it.

Using the online tool myPNOZ Creator, customers can assemble their own safety relay myPNOZ and receive “their” product pre-assembled and ready to install – for the first time in batch size 1 – and entirely without engineering software. In terms of the structure, the linking of individual functions and the whole procedure for the creation, simulation, order and delivery process, myPNOZ follows a new perspective and a new way of thinking!
