Description

  • 1-Channel 4-20mA Current Loop Transmitter I2C Mini Module
  • Powering NCD I2C Interface Devices
  • 12-Bit DAC MCP4725 / XTR115 4-20mA Current Loop
  • Unlimited I2C Expansion / Quad Channel Digital Isolator
  • One Channel 2 Wire 4-20mA Transmitter
  • Wide Loop Supply Range 7.5V to 36V

The National Control Devices 1-Channel 4-20mA Current Loop Transmitter I2C Mini Module converts I2C Data into a 4-20mA Output using a 12-Bit Digital to Analog converter (DAC). Uses an XTR115 4-20mA Current Loop Transmitter connected to an 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.

It is 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 and 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.

回路図無い(泣)

I2Cで制御できるモジュールがこれしか見つからないので、購入してみた。 Arduinoとか NCDのシステムの一つとして使っているかぎりにおいては多分問題ないのであろう。 回路図もなく、BOMもなく途方に暮れる
