The ICP DAS MQ-7244M is an Ethernet I/O device equipped with 8-channel DI and 8-channel DO, and supports MQTT protocol for connecting with a variety of digital sensors in Industrial Internet of Things (IIoT) applications. A web-based user interface is provided to configure the module, monitor the network connection status and I/O status, and control digital output channels on the module via web browser on a mobile device or computer.
The MQ-7244M features optical isolation for 2500 VDC of transient over-voltage protection, but doesn’t provide channel-to-channel isolation. Each output channel can drive up to 650 mA load, together with configurable power-on value and safe value. This MQTT protocol I/O module can be safely used in applications where hazardous voltages are present.
