M31-AXAX8080G-L 8DI+8DO RS485 LoRa 433M 30dbm Remote IO Module — Analog Switch Acquisition, Ethernet, Modbus TCP/RTU

The M31-AXAX8080G-L is a scalable remote I/O host designed for long-range wireless telemetry and local network integration. It provides 8 digital inputs and 8 digital outputs with RS485 interface plus Ethernet connectivity, and uses LoRa wireless at 433M with 30dbm output for extended coverage. The unit can communicate directly with E90-DTU data transmission radio. Protocol and compatibility: Supports standard Modbus protocol and protocol conversion, including Modbus TCP and Modbus RTU. It is compatible with a variety of configuration software, PLCs and touch screens, and allows custom Modbus address settings. I/O and network features: The network port is used to collect and control I/O and the device supports RS485 acquisition control I/O. It permits 5-way host access and simultaneous connections by up to 5 clients. Supported Modbus function codes: 01/02/03/04/05/06/15/16. Configuration and expansion: Offers 8 selectable baud rate configurations and supports DHCP or static IP addressing. In distributed IO mode the host can connect up to 16 IO expansion modules. The hardware includes provisions for mounting with positioning holes and guide rails. Design: The M31 series adopts a modular, scalable structural design suitable for remote monitoring and control applications where Modbus TCP/RTU interoperability and long-distance LoRa links are required.
