MQ-7244M/MQ-7252M/MQ-7255M
MQTT I/O Module with 8-ch DI, 8-ch DO
     
 
~ NEW ~    
Model: MQ-7244M Model: MQ-7252M Model: MQ-7255M
 
  • Built-in Web Server
  • Web HMI
  • Support for MQTT Protocol
  • 2-port Ethernet Switch for Daisy-Chain Topology
  • Dual Watchdog
  • Wide Operating Temperature Range: -25 ~ +75°C
  • Built-in I/O
    • DI: 8 Channels
    • DO: 8 Channels
 
The MQ-7244M, MQ-7252M and MQ-7255M are Ethernet I/O devices 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 DO lines on the module via a normal web browser on a mobile device or computer.

The MQ-7244M, MQ-7252M and MQ-7255M feature optical isolation for 2500 VDC of transient overvoltage protection but do not provide channel-to-channel isolation. Each output channel can drive up to 650 mA load, together with configurable power-on value and safe value. The MQ-7200M module can safely be used in applications where hazardous voltages are present.
