If you are looking for analog front-end input board for standard 4-20mA current loop. The I2C-AI418SV2 is an I2C analog to digital board. It is called I2C ADC board. The board can be connected voltage and current sources. It has 4 channels. Each channel accepts 0-5v, 0-10v, 0-20mA, 4-20mA, 0-40mA. So this board can connect to 4-20mA of sensors. Resolution of ADC can be selected as 12, 14, 16 and 18 bits. Which the most significant bit(MSB) is used for a sign bit. The Programable Gain Amplifier (PGA) can be programmed as 1,2,4 and 8. The board is necessary to interface to microcontroller through I2C bus that is compatible 100Khz, 400Khz and 3.4Mhz bus speed mode. Address for I2C bus are selected with two jumpers on the board. The I2C front-end analog to digital board can be configured up to eight addresses. It means eight boards can be connected to a single bus. Also the board has pull-up resistors for I2C bus which can be enabled or disabled with jumpers. The I2C ADC board wants only a single supply voltage from 2.7-5.5V.
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.
