Produktinformationen "DL-303 CO/CO2 Data Logger with Safety Alarm, RS-485/Ethernet/PoE"
The DL-303 CR records carbon monoxide, carbon dioxide, temperature, humidity and dew point together, with date and time stamps on every record. Readings are shown simultaneously on a 2.8-inch touch screen, and a single relay output can drive an alarm device or an indoor air quality (IAQ) control device.
Data can be read over RS-485 using DCON or Modbus RTU, or over Ethernet using Modbus TCP or MQTT. The unit can be powered from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block, which simplifies installation where a network cable is already present. Configuration is available through the touch screen or the built-in web server.
Logged data can be downloaded and exported to CSV for analysis. Free Windows utility software, iOS and Android apps are included, and multilingual on-screen messages can be shown to prompt operators. The device is listed with CE, UKCA, FCC, RoHS and WEEE certification.
