- 2-port Ethernet Switch (LAN Bypass) for Daisy-Chain Wiring
- Dual Watchdog
- Built-in I/O
Introduction
The MQ-7251M is an Ethernet I/O device equipped with 16-channel DI, 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 friendly web-based user interface is provided for users to configure the module and access the network connection status and I/O status via a normal web browser on a mobile device or computer.
The MQ-7251M features optical isolation for 2500 VDC of transient overvoltage protection but does not provide channel-to-channel isolation. It can safely be used in applications where hazardous voltages are present.
