4-20mA T Click is an add-on board in mikroBUS form factor. It's a compact and easy solution for adding an industry standard 4-to-20mA current loop communication protocol to your design. It features the ADuM1411 quad-chanel digital isolator, MCP4921 12-bit DAC as well as the XTR116 4-20mA current loop transmitter. The board communicates with the microcontroller via three SPI lines (SDI, SCK and CS). The board can be used with either a 3.3V or 5V power supply. An LED indicates the presence of power supply to the board. |

4-20mA R Click is an add-on board in mikroBUS form factor which serves as a receiver in a 4-20mA current loop standard. It features INA196 current shunt monitor, MCP3201 12-bit ADC as well as the TPS61041 DC/DC boost converter. It receives output current (4-20mA) from the transmitter and converts it into a voltage (0.4-2V). This voltage is converted into a 12-bit data signal in the MCP3201 A/D converter and sent via mikroBUS SPI lines. Together with 4-20mA T Click this board forms a complete 4-to-20mA current loop standard. It is designed to use either a 3.3V or 5V power supply. |
