【4AI+2DO】MA01-XACX0420 serial port(RS485) data transfer to configuration software or PLC
[Introduction]：The MA01-XACX0420 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 2 relay switch output (DO) by sending instructions from the serial port.
