  • XTR115 4-20mA Current Loop Transmitter
  • One Channel 2 Wire 4-20mA Transmitter
  • 2 Devices On One I2C Bus
  • Ideal For Industrial Control
  • Wide Loop Supply Range 7.5V to 36V
  • 2 Wire, 4-20mA Current Loop Transmitter
  • Low Span Error
  • Low Non-linearity error

This 4-20mA Current Loop Transmitter Board converts I2C Data into a 4-20mA Output using a 12-Bit Digital to Analog converter (DAC). This 4-20mA Current Loop Transmitter Board usages an XTR115 4-20mA Current Loop Transmitterconnected to a MCP4725 Digital to Analog Converter. The MCP4725 has one address jumper, allowing 2 devices can be connected at the same time on a single I2C bus. Its also possible to connect more than 2 devices on one bus using the I2C multiplexer. The On-board XTR1115 4-20mA Current Loop Transmitter has a wide Loop supply range from 7.5V to 36V.

This 4-20mA current loop transmitter has on-board screw terminals which make it easy to connect. It also has a Vref exposed pad for external voltage reference with a preset Vref of 2.5V.

A DAC value of about 670 will output 4mA of current; similarly, a value of about 3460 will output 20mA of current.

What is the DCUBE I2C Interface?

DCUBE is the creator of plug and play modular hardware using the  I2C Interface connector standard. DCUBE I2C devices allow you to chain together several devices on the I2C bus, and communicate to each device individually at high speed (subject to the limitations of I2C). The DCUBE I2C Interface uses a standard 4-Pin I2C Input and I2C Output connector. DCUBE I2C devices communicate 5V I2C data and provides 5V DC power through this connector. DCUBE I2C devices use standard I2C communications for all data transport, which is supported by nearly every microcontroller in production today. The DCUBE I2C Interface is strictly a 5V standard, which is ideal for transport across longer cables. DCUBE I2C devices always include a 6″ (152mm) 4-conductor I2C cable. DCUBE I2C Mini Modules always include a 3″ (76mm) 4-conductor I2C cable. Cables and connectors are available separately for designers who would like to include their own DCUBE I2C Interface into their designs.

Plug and Play Connectivity
DCUBE I2C devices will plug in to any available DCUBE I2C Output. This includes just about everything we make in the DCUBE IoT Category, including all DCUBE IoT devices. We also manufacture a wide range of I2C adapters that make it easy to plug DCUBE I2C Devices directly into most computing platforms. The DCUBE I2C Interface adapters are available for Arduino, Banana Pi, BeagleBone, Bluz, C.H.I.P., ESP8266, Onion Omega, Particle Photon and Electron, PyCom, Raspberry Pi, 2, 3, and Zero, and Windows. We are always working to add new platform support for DCUBE I2C devices. DCUBE I2C Interface devices are compatible with just about everything in the microcontroller industry.

Unlimited I2C Expansion
Based on our plug-and-play I2C interface standard, all DCUBE I2C devices are equipped with a I2C output port, making it easy to expand to a wide variety of sensors, current monitors, relay controllers, PWM controllers, and much more! We are always designing new expansions for our modular plug-and-play I2C framework. We are dedicated to building a product line of interconnected devices to simplify all forms of automation. Re-use or upgrade your hardware in seconds by selecting the modules that best fit your needs, and chaining them together using the included I2C expansion cables!

Powering DCUBE I2C Interface Devices
Some DCUBE I2C devices require a external power supply, others may be powered through the 4-Pin I2C bus connector at 5VDC, and other devices are jumper selectable between external and I2C bus power. All I2C mini modules are powered through the 5V I2C bus connector, greatly simplifying connectivity.
