The MQ-7244M, MQ-7252M and MQ-7255M are Ethernet I/O devices equipped with 8-channel DI and 8-channel DO, as well as the MQTT protocol is 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 module, monitor the network connection status and I/O status, and control DO lines on the module via a normal web browser on a mobile device or computer.

The MQ-7244M, MQ-7252M and MQ-7255M feature 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, together with configurable power-on value and safe value. The MQ-7200M module can safely be used in applications where hazardous voltages are present.
