Features

  • Built-in Web Server
  • Web HMI
  • Support Modbus TCP and MQTT Protocols
  • 2-port Ethernet Switch (LAN Bypass) for Daisy-Chain Wiring
  • Dual Watchdog
  • Built-in I/O
    • DI: 8 Channels
    • DO: 8 Channels

Introduction

The MQ-7252M is an Ethernet I/O device equipped with 8-channel DI and 8-channel DO, as well as the MQTT and Modbus TCP protocols, which are supported for connecting with a variety of digital sensors in Industrial Internet of Things (IIoT) applications. A web-based user interface is provided to configure the module, monitor the network connection status and I/O status, and control digital output channels on the module via a normal web browser on a mobile device or computer.

The MQ-7252M features optical isolation for 2500 VDC of transient overvoltage protection but doesn't provide channel-to-channel isolation. Each output channel can drive up to 650 mA load, together with configurable power-on value and safe value. It can safely be used in applications where hazardous voltages are present.

Applications

  • Factory, Building and Home Automation Remote Maintenance.
