It is imperative that you observe the safety instructions with regard to the electrical voltage! It is particularly important to ensure that a power supply unit with functional extra-low voltage (PELV) is used.

 

All Irinos boxes are supplied via a common 24 V voltage. This can be supplied at any point in the system at a socket or terminal provided for this purpose. It is distributed over the entire system via the EC-Link- and qLink- cables.

An exception are the digital inputs/outputs, which must be fed in separately depending on the box type. This also makes it possible to include the digital inputs/outputs in an emergency stop circuit without completely switching off the Irinos system.

 

The voltages required for measurement and communication are generated internally via galvanically isolated DC/DC converters and, if necessary, downstream linear regulators. This means that the internal voltages of several Irinos boxes are completely separated from each other. This increases the interference immunity. This is a prerequisite for precise measurement results. In addition, the formation of ground loops is prevented.

Please note, however, that a stable and low-noise 24 V supply is a prerequisite for proper operation of the Irinos system. Therefore use a separate power supply unit with functional extra-low voltage (PELV) for the Irinos system.
