Discontinued product, the replacement product is I2C-AI418SV2.
Cables are not included.
If you are looking for analog input board for standard 4-20mA current loop. This 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-bit. Which the most significant bit(MSB) is used for a sign bit. The 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 by two jumpers on board. The I2C ADC board can be configured up to eight addresses. It means eight boards can be connected together on the same bus. Also the board has pull-up resistors for I2C bus which can be enabled or disabled by jumpers. The I2C ADC board wants only 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.
