Ethernet IO Module used in Tunnel Monitoring System

The Ethernet IO Modules suitable for IIOT Applications and Industrial Automation systems. In Traffic Tunnel Monitoring and control system, using the Ethernet IO Module can easy to form the whole system.
The M Series Ethernet IO Modules provides different I/O for choice, and each Ethernet IO Module provides 1 RS485, it can performs as Modbus Master to control the other smart device, and for upstream, it can communicate by Ethernet with high speed. see below:

The Ethernet IO Module can be connect to controllers, eg.: PLC or through Ethernet over MQTT Protocol to monitoring center, Cloud Platform directly.
