4-20 mA T click

4-20mA T Click is an add-on board in mikroBUS form factor. It’s a compact and easy solution for adding 4-to-20mA industry standard communication protocol to your design. It features ADuM1411 Quad-chanel digital isolator, MCP4921 12-bit DAC as well as XTR116 4-20mA current loop transmitter. 4-20mA T Click communicates with target board microcontroller via three mikroBUS SPI lines (SDI, SCK, CS). Together with 4-20mA R Click this board forms a complete 4-to-20mA current loop standard. The board is designed to use 3.3V and 5V power supply. LED diode indicates the presence of power supply.

The board receives the input digital signal from the microcontroller and sets the output loop current (4-20mA).
SPI communication interface.
Galvanic isolation provided through ADuM1411 optocoupler.
On-board screw terminal for easier connection.
