I2C 4-20ma & 0-10v ADC Din-rail

I2C-AI418M






I2C 4-20ma & 0-10v ADC Din-rail

I2C-AI418M


This is an analog to digital converter board through 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 30 volt. 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. The board has ADC on board to converts the analog value to digital value. The ADC can be selected resolution: 12,14,16,and 18-bit. The most significant bit (MSB) 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 microcontrollers 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 ,and you can enable or disable them by jumpers. The 10Kohm resistor is suitable for 100KHz bus speed. The board needs only single supply voltage from 2.7V to 5.5V ,and the board can be plugged on din-rail PCB holder.

To prevent damage to the board. Don't plug and/or unplug I2C cables on the board while a power supply still turns on. Turn off a power supply before plug and/or unplug I2C cables on the board.
