1 Brief Introduction

MA02-AACX2220 supports the acquisition of 2-channel sensor switch input (DI) and 2-channel sensor analog input (AI),
which is converted into serial port (RS232) 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 controls 2 relay switch outputs (DO) by
issuing commands through the serial port.
