This 4-20mA Current Loop Transmitter Board is a Digital to Analog board. It has an onboard 16 bit DAC. This 4-20mA Current Loop Transmitter Board uses an XTR115 4-20mA Current Loop Transmitter and an AD5696 Digital to Analog Converter. The AD5696 is a 16 bit DAC. AD5696 has two address bits, so 4 devices can be connected at the same time on one bus. If more are needed you can also connect more devices on one bus using the I2C multiplexer. The Onboard XTR1115 4-20mA Current Loop Transmitter has a wide Loop supply range from 7.5V to 36V.
This 4-20mA current loop transmitter has onboard screw terminals which make it easy to connect. It also has a Vref exposed pad. Vref for the XTR115 is 2.5V.
At DAC value around 894 the output current value is 4mA and at DAC value around 4613 the output current value is 20mA.
