[Introduction]:MA01-AXCX4020 supports the acquisition of 4-channel sensor switch input (DI), which is converted to serial port (RS485) and data is transmitted to configuration software or PLC. The serial port I/O networking module (also known as "remote IO") that controls 2 relay switch outputs (DO) by issuing commands through the serial port to realize remote acquisition and control functions.
