Temperature, Humidity and Light Sensor with RS485 port

The KET-THL-210 combines a digital ambient temperature and relative humidity sensor in a compact device which, together with the integrated light sensor, provides complete environmental monitoring. It communicates with the X-Monitor network through the RS485 ModBUS RTU interface. The KET-THL-210 is powered by 12 ÷ 24 VDC / 12 ÷ 20 VAC. The integrated thermostat function allows the user to communicate the desired temperature set to the control system. The LCD display shows the values detected by the device and allows its configuration.
