M31-U series distributed IO host  Product Introduction

The M31-U series high-performance distributed IO host supports standard Modbus TCP and Modbus RTU protocols and is suitable for data acquisition and control. Distributed IO host specific models are M31-AFAX4440G-U, M31-AXAX8080G-U.The device is equipped with 10/100M adaptive dual Ethernet interfaces and supports switch functions.The internal bus speed can reach up to 1ms. It has the characteristics of switching and analog disconnection output reset to ensure that it can be restored to the preset state when communication is interrupted.

The modular design allows users to flexibly expand according to actual needs. When the existing configuration is not sufficient to meet specific application requirements, users can easily add matching IO expansion modules without replacing the entire system, effectively saving costs and simplifying the field deployment process. The device integrates real-time status diagnostics to help continuously monitor communication conditions.

High performance distributed IO host

This M31-U distributed IO host allows the connection of up to 16 IO expansion modules (including the host itself) and is built in compliance with the EMC Level 3 protection standard. The IO input and output, RS485 and power supply are fully isolated, providing excellent electromagnetic compatibility, outstanding performance and high reliability.
