Attention
Integrated flyback diode is designed for connection of devices within the group of digital outputs. Using
flyback diode for different connections may cause permanent damage to the device.
2.4.6 Analog input connection
Analog input serves for reading voltage value in range 0-10 V or current in range 0-20 mA. The type of
measurement is configured depending on used software.
Negative pole of measured external device is to be connected to screw connector of AGND while
positive pole is to be connected to screw AIY.X connector.
Note
In default Neuron is set to voltage measurement to avoid potential device / sensor damage in case of
inappropriate external device.
Attention
Depending on type output (either voltage or current) of external device it is first necessary to check
configuration of measurement through the chosen software before actual connection of the external
device.
The following pictures illustrates connection of voltage and current source on connectors AI and AGND.
