Sensor for One Digital Temperature and Humidity or CO2 Probe, Ethernet Output and PoE

The TA3611 is a flexible Ethernet sensor designed for connecting one external digital probe.

It supports both temperature and humidity probes as well as the NDIR CO2 probe CO2G-10, allowing the device to be adapted to a specific application without hardware changes. Thanks to the innovated platform, the device offers a modern web interface, advanced security, and broad support for communication protocols.

A large backlit LCD display ensures clear local visualization of measured values, including dew point or absolute humidity calculation, while LED and acoustic signaling alert to alarm states.

The TA3611 is the ideal choice for environmental monitoring in locations where flexibility of the measured variable and easy integration into monitoring systems are required.

Main Benefits:

  • Support for T+RH or CO2 digital probes
  • Flexible use of one device for different applications
  • Backlit LCD display, acoustic and LED alarm signaling
  • Power supply 5–24 V or PoE
  • Integrated backup memory
  • Modern web interface, IPv4/IPv6 support, Modbus TCP, COMET Cloud, and fully encrypted communication (HTTPS, SNMPv3, TLS)
  • Integrated detachable bracket for easy installation
