Andino X1 - Raspberry Pi on DIN Rail

The Andino X1 is a microcontroller board for the Raspberry Pi in a DIN-rail housing for installation in a control cabinet. It is used to adapt digital inputs and outputs for a voltage of 24 V. The X1 has its own microcontroller for precise signal preprocessing and adaptation of signal generators and actuators. It also contains a Raspberry Pi. The inputs and outputs as well as the power supply of the Pi are optimally protected. Communication between the microcontroller and the Pi takes place via the UART interface.
