I2C 4-20ma & 0-10v ADC TVS

I2C-AI418ML


This is an analog to digital converter board over I2C bus; I2C ADC BOARD. The board has 4 analog inputs. Each input can be connected to voltage or current source, so you can connect 0-5v or 0-10v to each input when you want to measure voltage. While, you can connect 0-20ma, 4-20ma or 0-40ma to each input when you want to measure current. Each input has over-voltage protection circuit. The over- voltage protection circuit can protect continuous voltage; up to 30volt. This circuit protects board damaging from human error and wrong connection. Also, each input has transient suppression device. This device protects board from external transient voltage when the input is connecting to long wires of sensor. There is ADC on board to convert the analog value to digital value. Resolution of ADC can be selected: 12,14,16, and 18 bits. The most significant bit (MSB) of digital value is used for a sign bit. For this board, the sign bit is away zero. It represents a plus sign. The digital value can be accessed by microcontroller through I2C bus. The PGA of ADC can be programmed through I2C bus too. The bus speed is compatible to standard mode: 100Khz, 400Khz, and 3.4Mhz. Address of each board is selected by two jumpers. The address can be eight different addresses. So you can connect eight boards together on a bus. The board has two of 10Kohm pull-up resistors for I2C bus lines, and you can enable or disable them by jumpers. However the 10Kohm resistor is suitable for 100KHz bus speed. The board needs only single supply voltage from 2.7V to 5.5V.

  • Programmable Gain Amplifier(PGA)
  • On-board pull-up resistors for I2C bus
  • Up to 8 boards on a bus
  • Compatible with most microcontrollers
  • Single supply operating voltage: 2.7V to 5.5V
  • Inverse polarity protection circuit for supply voltage
  • 30V over-voltage protections for each input channel
  • Input transient suppression for each input channel
  • PCB size 67.50x36.00mm

Includes:
  • 1x Board

Notes:
  • This board uses 4-pin connectors for I2C bus.
