Universal modbus inputs module
jatel.sk
Specification:
Supply: 12 - 30V / 50mA
Core: Arduino Nano
Number of inputs: 6
Input types: TTL / TTL with pull-up 2k2 / 0-10V / 1-10V / 0-20mA / 4-20mA
Number of outputs: 2
Output types: relay contact 10A/240VAC
Communication: Modbus RTU 485
Mounting: DIN 4M
The firmware for this board is not yet available and therefore the board is not even tested!
I'm looking for a person to collaborate on writing an FW for the UMI6R2 board in the Arduino IDE.
Description
Low cost universal modbus controll unit for low cost sensors and actuators from China:
NTC
Hall Flow Sensor
DHT22
DS18B20
Pressure Sensor
Electric Valve
Electric Solenoid Valve
etc...
