This is an I2C bus analog to digital converter board, I2C ADC board. Voltage and current sources can be con-nected to each input of the board. The board converts the analog values to digital values then the digital values can be processed by microcontrollers. The microcontrollers can read the digital values of the board through the I2C bus. The I2C ADC board has four inputs. Each input accepts voltage 0-5V and 0-10V and current 0-20mA, 4-20mA, 0-40mA and 0-80mA. The resolution of digital value is 16 bits which the most significant bit (MSB) is used for a sign bit.
The board needs only a single supply voltage from 2.7V to 5.5V for operation. The I2C bus is compatible with the standard 100Khz, 400Khz and 3.4Mhz modes.
The I2C bus addresses are selected by jumpers. The board can be configured to one of four addresses. It means up to four boards can be connected on a single bus. The board has a pair of 10K ohm pull-up resistors for I2C lines. They can be enabled or disabled with the jumpers. The 10K ohm resistors are suitable for 100KHz bus speed. The board can stack on a 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.
