myPNOZ Safety Relay


With the online tool myPNOZ Creator, users can assemble their myPNOZ: it’s delivered pre-assembled, set up, tested, and ready to install. No programming knowledge is required to use myPNOZ Creator, as the logic links for the safety functions are defined on myPNOZ via the modules that are selected and the sequence in which they are plugged in.


The safety relay monitors safety functions such as E-STOP, safety gates, light curtains, two-hand controls IIIA/C, and enabling switches. It consists of a head module with up to a maximum of eight expansion modules, which can be freely combined. In the online tool, you can assemble a needs-based safety solution from a wide range of options. Users can switch between a logic view and a hardware view.


Depending on the safety requirement, users interconnect safety functions such as E-STOP or safety gate using logic AND/OR connections. The online tool uses a symbol to indicate any logic errors in the safety function sequence. Users can add any further safety functions at will and also define details—such as delay-on energization and delay-on de-energization for example. Users can check immediately whether a circuit or safety design meets their own requirements in the myPNOZ Creator, using the simulation in the online tool.


It's is possible to define the number, type, and logic connection between the safety functions, based on what customers need for their plant. The Creator uses these details to automatically calculate which modules are needed and the sequence in which they must be inserted. The plug-in sequence results from the connection logic for the safety functions. Due to this internal combination logic, the process requires no programming knowledge. The product that is generated can be ordered directly via the online tool, and users can order a previously defined configuration of myPNOZ with just a click of the mouse. The safety relay is delivered pre-assembled and ready to install. Each myPNOZ is given a unique type code so that if necessary the same system configuration can be re-ordered at any time.


The safety relay monitors safety functions such as E-STOP, safety gates, light curtains, two-hand controls IIIA/C, and enabling switches. It consists of a head module with up to a maximum of eight expansion modules, which can be freely combined. The modular myPNOZ offers up to 12 different expansion modules in total: four output modules, four input modules, and four input/output modules. Each input module can monitor two safety functions, which not only minimizes hardware costs but also reduces the wiring. Multiple safety sensors can be monitored without the need to wire multiple relays—as was the case previously. With myPNOZ it is also possible to form multiple safety zones, which independently monitor plant sections that operate separately. This helps to increase the availability of the plant because machine parts can be shut down independently from each other.


The slimline 17.5 mm head module already has a higher-level safety function. This works on all outputs, regardless of any other potential safety zones. The output modules either switch immediately or with a time delay and are available with relay or semiconductor outputs. myPNOZ enables safety functions to be AND / OR linked, enabling customized applications.


The modules on myPNOZ are easily connected using BUS connectors. In addition, the whole system is supplied with power via the head module. As a result, only the head module needs to be connected to the power supply, which reduces wiring. So the plant can be commissioned quicker and can also be optimized with a view to maintenance costs: if just one module needs to be swapped, individual modules can be exchanged immediately without dismantling the whole system. It also has expanded diagnostics via LED for each module and each safety input. This accelerates troubleshooting and reduces downtimes. The range of modules and the fact that they are easy to handle mean that users can always assemble the solution that’s right for them. That guarantees users maximum flexibility over the whole lifecycle, even when subsequent changes are needed.


myPNOZ represents an efficient, safe solution for mechanical engineering. What’s more, the safety relay can be used in various industries. Users benefit from safety applications of simple to average complexity, when two to a maximum of 16 safe input functions are to be monitored, without using engineering software.
