The MIKROE-1296 4-20mA T Click Board integrates 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). The board is designed to use 3.3V and 5V power supply. LED diode indicates the presence of power supply. It’s a compact and easy solution for adding 4-to-20mA industry standard communication protocol to your design.
