[Introduction]：MA01-XACX0440 is a support for the acquisition of four sensor analog inputs (AI), converted to serial port (RS485) data transfer to configuration software or PLC. The serial I/O networking module (also known as "Remote IO")for remote acquisition control function is realized by controlling the 4 relay switch output (DO) by sending instructions at the serial port.
