Module Ethernet MQTT 8 kênh đầu vào số (DI) + 8 kênh đầu ra số (DO) ICP DAS MQ-7255M CR
The MQ-7255M is an Ethernet I/O device 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 digital output channels on the module via a normal web browser on a mobile device or computer. The MQ-7255M features optical isolation for 2500 VDC of transient overvoltage 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. It can safely be used in applications where hazardous voltages are present.
