[Introduction]：The MA01-AACX2240 is a support for the acquisition of 2 sensor switching inputs (DI), 2 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.
