Before deciding the design of your safety control system, it is necessary to understand which performance level you need to achieve in accordance with ISO-13849. A risk assessment is therefore required. At Phoenix Contact we have an App which can be used on an iPhone or iPad, giving the user an interactive risk assessment guide, \"safetytherefore\u00a0determining the performance level of the machine or application.<\/p>\n

You can download the free App in iTunes here.<\/p>\n

How do I know I have achieved the required performance level ?<\/strong><\/p>\n

One easy way to validate that you have achieved the correct performance level for your machine\/application is to use a free software tool called SISTEMA. This is free to download from our website\u00a0here<\/a>.<\/p>\n

You can also download a library of Phoenix Contact devices from the above link, which can be accessed within SISTEMA. This means that you don\u2019t need to waste time and effort hunting for safety characteristic values. You simply select the product you wish to use and the SISTEMA software will calculate the rest.<\/p>\n

Many customers have three separate safety input functions on a machine and wanted a bit of safety logic, without the need for software or dip-switches. The MXF Safety Relay is the perfect solution, the below diagram gives a visual representation of the safety operating principle.<\/p>\n
