1. Product introduction
MA02-AACX2240 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 and control function by
issuing commands through the serial port to control 4 relay switch outputs (DO).
