In the emergency warning system of a tunnel, we need to control the cameras and to receive signals from smoke sensors and transmitters.
We can build a real time monitoring and control system over the Internet with ET-7000 series. They can be linked to devices like cameras, smoke sensors and transmitters. They can send digital output signals to devices like web based LED displays. These displays can help warn drivers about obstructions to keep the roadway smooth and safe. The ET-7000 series have built in web servers, web HMI, dual watchdog, I/O pair connection and support Modbus/TCP protocol.

Used Hardware:
ET-7052
8-channel Isolated Source Type Open Collector Output and 8-channel Isolated Digital Input Module with 32-bit Counters.
The ET-7000, a web-based Ethernet I/O module, features a built-in web server which allows configuration, I/O monitoring and I/O control by simply using a regular web browser. Remote control is as easy as you surfing the Internet.
Besides, with the web HMI function, no more programming or HTML skills are needed; creating dynamic and attractive web pages for I/O monitoring and I/O control would be fun to engineers ever after.
The ET-7000 offers easily and safely access for users from anytime and anywhere! In addition, the ET-7000 also supports Modbus/TCP protocol that makes perfect integration for ET-7000 to SCADA software.
The ET-7000 is designed for applications to industrial monitoring and measurement; therefore, we have made it toughly enough to survive the harsh and rough environment.
The module contains 2-way isolation from noise and surges, one for digital inputs and the other for Ethernet.
The ET-7000 has got a wild range of power input (10~30VDC) and operating temperature (-25°C~+75°C).
