Introduction
The DTU200EG is a device designed for monitoring systems and general data acquisition . It is mainly used to collect various environmental and dynamic variables, alarm signals, etc. It can realize data acquisition, output control, remote communication and other functions, and integrate all functions into one platform.
Powered by an external power source (AC/DC) It can provide 2-channel general analog measurement ( AI) or 2-channel digital input (DI), 2-channel It features an RS485 serial port, one 12V output, and one Ethernet port.
This monitoring subsystem directly collects and processes data from devices and sensors within the micro-station. Data is uploaded to the monitoring center via wireless communication or Ethernet . The DTU200EG supports backup battery functionality after a power outage. It is designed for low-power, low-cost, low-data-traffic deployment scenarios.
