This board is data acquisition module used to convert analog quantity into its digital equivalent. It has isolated RS-485 interface and the protocol implemented is MODBUS RTU. It has 8 channels of analog input, which can be configured as voltage input or current input (Jumper selectable). It has a programmable gain amplifier (PGA) from 1 to 128. At gain of 1 the input range is 0-10V and at gain of 128 it has input range of 0-78.125mV.
For current input the range is from 0-20mA or 4- 20mA.
It provides user configurable scaled output.
