[Introduction]：MA01-AXCX4040 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 called "remote IO") that realizes the remote acquisition and control by issuing commands through the serial port to control 4 relay switch outputs (DO)
