Temperature, Humidity and Light Sensor for outdoor with RS485 port

The KET-THL-210.S is a sensor designed for outdoor positioning thanks to the high degree of protection of the container and the temperature and relative humidity sensors protected from the weather, also integrates a light sensor for a complete environmental monitoring.

It communicates with PLC/SCADA through the RS485 ModBUS RTU interface.

The KET-THL-210.S is powered by 12 ÷ 24 VDC / 12 ÷ 20 VAC.
