Increase number of safe outputs

04 July 2016

With safety technology a major consideration in the automation industry, it is now possible to easily increase the number of safe outputs within a system by using Murrelektronik's combined solution: the modular Cube67 fieldbus system and the safe fieldbus module MVK Metal Safety. That saves spaces in the cabinet because safety relays are no longer necessary.

If there is an emergency on the shop floor - for example a guard door has been opened or someone has activated a light curtain - outputs have to be switched off immediately. Combining safety relays with K3 fieldbus modules is an easy method to achieve safe outputs. This is a practical solution for smaller applications with basic requirements.

In order to design an installation solution based on Cube67 that meets the highest safety requirements, a combination of the compact and safe fieldbus module MVK Metal Safety with Cube67 K3 modules is an excellent solution. With the safe outputs of MVK Metal Safety – controlled by a PROFINET/PROFIsafe controller – it is possible to create up to 12 safe outputs on the K3 module. They are split into two safety circuits, each with three ports that have dual functions. This multiplies the number of safe outputs and is a simple and efficient method to increase the competitiveness of your machines and systems.
