The current VDE regulations must be observed for all devices which require an electrical voltage for
their operation. Particularly relevant for this product are the VDE guidelines VDE 0100, VDE
0550/0551, VDE 0700, VDE 0711 and VDE 0860. Please also observe the following safety instructions:
 Do not use the Andino X1 if it is damaged.
 Components do not belong in children's hands!
 When handling products that come into contact with electrical voltage, the valid VDE regulations
must be observed.
 In commercial facilities, the accident prevention regulations of the Association of Professional
Cooperatives for electrical installations and operating equipment must be observed.
 Components, subassemblies or devices may only be commissioned if they have previously been
installed in a housing in a safe manner. During installation, they must be disconnected from the
power supply.
 The product must not be dropped or subjected to strong mechanical pressure as it may be
damaged by the effects.

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 (2/3). 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.
The Andino X1 offers the following advantages:
 The sensitive GPIO of the Raspberry Pi are protected.
 Fast signals can be precisely detected by the microcontroller.
 Actuators and sensors can be electrically connected to the Raspberry Pi.
 It provides an industrial power supply for the Raspberry Pi.
 Customized adapters from the Raspberry Pi GPIO or the micro controller IO can be
connected electrically to terminals.
 Provides mounting on a DIN rail for installation in manifolds.
Andino X1 is designed for installation in switch cabinets. The integrated voltage regulator is designed
for an input voltage of max. 24 V. The protection class of the housing is IP20. The device must be
protected against splashing water, moisture and dust.
With a 24 volt operating voltage, the current consumption at +5 volts must not exceed 2.5
Ampere.
Any use other than specified is not permitted! Modifications can lead to damage to this product. Short
circuit, fire, electric shock, etc. The manufacturer is not responsible for all personal injury and material
damage resulting from non-intended use.
Please note that operating and / or connection errors are outside our sphere of influence.
Understandably, we cannot accept any liability for damages resulting from this.

Power supply Voltage regulator with EMC protection circuit and polarity reversal protection.
Power secondary +5 Volt max. 2.5 Amps!
Digital inputs Galvanically isolated inputs for 24 volts. Isolated up to 5 kV.
Digital outputs Relay outputs for 120VAC and 2 Ampere.
Microcontroller ATMEGA 168 PA with 8 MHz with Arduino compatible bootloader.
RTC real-time clock, temperature-compensated and battery-buffered.
Extension plug slot for customer-specific extensions on five screw terminals.
Raspberry Pi Intake of a Raspberry Pi 2 or 3 Model B.
The Arduino compatible microcontroller is connected to the Raspberry Pi via the UART interface.
The interface / dev / ttyAMA0 is used on the Raspberry Pi.
Via this interface the Raspberry can communicate with the controllers and program it.
If no Raspberry Pi is inserted, the microcontroller can be addressed via USB (Virtual Com Port) from the
outside. This allows the microcontroller to be programmed from a Windows PC with Arduino IDE
installed. To do this, set the jumper black to "USB".

With the plug-in connector 2-4 the circuit can be powered by the +5 Volt from the USB
connector. This is mainly used to program the controller and test the firmware.
Please note that this bridge is not plugged in when the Raspberry Pi is used or the
circuit is supplied with +24 volts!

The housing cover is held by four clamps. To ensure a good hold of the lid, the clips are relatively tight.
Pull the brackets one after the other on one side and slightly lift the lid.
Repeat the process on the other side. Do not use force.
When mounting the cover, please note the cutouts. The lid can not be twisted.
The Raspberry Pi is placed on the head, lying on the pin header. Raspberry Pi 2 or 3 Model B can be
used. The power supply of the Raspberry Pi is taken over by the internal voltage transformer.
We recommend the use of heat sinks for the CPU and the USB hub chip of the Pi!
