1 Introduction

1.1 Brief Introduction

MA02-XACX0440 supports the acquisition of 4-channel sensor

analog input (AI), which is converted to 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).

1.2 Features

★Support Modbus RTU protocol;

★Support various configuration software/PLC/touch screen;

★RS232 acquisition and control IO;

★DC 8～28V power supply;

★4 analog inputs AI (0～20mA/4～20mA);

★4 switch output DO (relay);

★Switch output (DO) supports level mode and pulse mode;

★Input collection port isolation protection;

★Communication baud rate 1200～115200 (default 9600), support custom setting;

★Supports 1～247 slave stations, 5-digit DIP switch can set 1～31 address code, more than 31 can

be set by software.
