Features

The MQ-7253M is an Ethernet I/O module designed with 2-port Ethernet Switch and has 16-channel DI and is communicable over MQTT protocol. The MQTT protocol allows connectivity with various Industrial Internet of Things (IIoT) applications. The MQ-7253M is designed with a user-friendly, web-based interface that provides 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-7253M is equipped with optical isolation for 2500 VDC of transient overvoltage protection but do not provide channel-to-channel isolation. This module is designed to be safely used in applications where hazardous voltages are present.
