Analog input converter on LAN / RS485
The compact Nano Analog Input module is designed to transmit the measured current or voltage value via selected Internet protocols over the LAN network and additionally with the Modbus RTU protocol via the RS485 port.

Highlights
The module supports sensors:
- sensors with voltage output 0-5V,
- sensors with voltage output 0-10V,
- sensors with current output 4-20mA,
- sensors with current output 0-20mA.
The process of processing the measured value is configured using a mathematical function – conversion of the measured value and setting the range of the sensor and unit.
Nano Analog Input is equipped with a red, 7-segment LED display, which indicates, among others, currently measured value.
Communication
The module is equipped with LAN and RS485 ports which enable communication through:
- embedded web server,
- Windows and Linux command line programs,
- HTTP,
- Modbus TCP,
- Modbus RTU,
- SNMP,
- own application, via TCP (shared protocol),
- MQTT (Inveo broker).
Use of the device
The input configuration can be carried out in the Input tab.
The Input Configuration table allows definition of input settings, i.e. sensor name, input type (4-20mA, 0-20mA, 0-5V or 0-10V) and the range of the sensor for the input range (Range Min, Range Max)
Nano Analog Input software allows the user to set an alarm in case of exceeding defined thresholds for the values read from the sensors. The alarm status is visible as a virtual input and available through most protocols. The alarm condition is displayed on the device’s display by blinking, and indicated on the home page.
