Introduction
The MQ-7251M and MQ-7253M are Ethernet I/O devices equipped with 16-channel DI, as well as the MQTT protocol is supported for connecting with a variety of digital sensors in Industrial Internet of Things (IIoT) applications. A friendly web-based user interface is provided for users to configure module, access the network connection status and I/O status via a normal web browser on a mobile device or computer.
The MQ-7251M and MQ-7253M feature optical isolation for 2500 VDC of transient overvoltage protection but do not provide channel-to-channel isolation. It can safely be used in applications where hazardous voltages are present.
