Features

The MQ-7244M is an Ethernet I/O module designed with 2-port Ethernet Switch and has 8-channel DI and 8-Channel DO . It supports the MQTT protocol allowing connectivity with various Industrial Internet of Things (IIoT) applications. It is equipped with a user-friendly, web based interface, allowing easy configuration, overseeing the network connection status and I/O status, and having control over DO lines on the module via a normal web browser on a mobile device or computer.

The MQ-7244Mis equipped with optical isolation for 2500 VDC of transient overvoltage protection but do not provide channel-to-channel isolation. Each output channel can drive up to 650 mA load, and together, can configurate power-on value and safe value. This module is designed to be safely used in applications where hazardous voltages are present.
