Description

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.

IoT Motherboard Compatibility

This is an I²C Master Device, capable of directly connecting to any of our Cross-Platform I²C Slave Devices using the I²C Output. It is directly compatible with:

Particle Electron
Particle Photon (Particle.io)
Bluz Module (Bluz.io)
ESP8266 Module

If using a Particle module, the PKFR Key Fob Receiver overlay shield may be used.

This device may be converted for direct use with:

Arduino Nano using the Arduino Nano Adapter
Arduino Micro using the Arduino Micro Adapter
Onion Omega 1&2 using the OC Adapter
Pycom WiPy using the WiPy Adapter
Adafruit Huzzah ESP8266 using the Adafruit Huzzah Adapter

This device may be converted to an I²C slave device using the Slave Adapter, ideal for use with Raspberry Pi, Beaglebone, Arduino Uno, and BridgeX5.
