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.
