SHT20 Temperature Humidity Control Module 10A RS485 Controller Transmitter Description: 10A Temperature Humidity Control Module Temperature measurement range：-20℃~60℃ Humidity range：00%~100%RH Control precision：0.1℃ 0.1%RH Test probe：Integrated sensor Output type：Relay output Output capacity：Maximum 10A Size：57*60*20mm Feature: Automatic recognition of working mode：starting temperature > stopping temperature, cooling mode 'C'; Start temperature < stop temperature, heating mode 'H' Refrigeration mode；When the detection temperature is greater than or equal to the starting temperature, the relay is switched on, the red indicator light is on, and the refrigeration equipment starts working.When the test temperature is no more than or equal to the stop temperature, the relay is closed, the red indicator is off, and the refrigeration equipment stops working Heating mode：When the detection temperature is no more than or equal to the starting temperature, the relay is switched on, the red indicator light is on, and the heating equipment begins to work. When the detection temperature is greater than or equal to the stop temperature, the relay is closed, the red indicator is off, and the heating equipment stops working Temperature correction function OFE (10.0 ~ 10.0 ℃) :The system works for a long time and may have deviation. The actual temperature = measured temperature + calibrated value through this function is corrected. Automatic recognition of working mode:The system automatically recognizes working mode according to starting humidity/stopping temperature; start humidity > stop humidity, dehumidification mode 'd'; Start humidity < stop humidity, humidity mode 'E'; Dehumidification mode:When the detection humidity is greater than or equal to the starting humidity, the relay is switched on, the green indicator light is on, and the dehumidification equipment begins to work.When the detection humidity is no more than or equal to the stopping humidity, the relay is closed, the green indicator is off, and the dehumidification equipment stops working. Humidification mode:When the test humidity is less than or equal to the starting humidity, the relay is switched on, the green indicator light is on, and the humidifying equipment begins to work.When the test humidity is greater than or equal to the stop humidity, the relay is closed, the green indicator is off, and the humidification equipment stops working The humidity correction function of RH (10.0 ~ 10.0 ℃) :If the system works for a long time, there may be deviation. The actual humidity = measured humidity + calibration value is corrected through this function. Package Included: 1PC*Digital Temperature Humidity Control Module 10A High Precision Controller SHT20 Temperature Humidity Transmitter Product adopts industrial-grade chip, high-precision SHT20 temperature and humidity sensors, ensure the products with good reliability, high precision and interchangeability. Adopt RS485 hardware interface (with the lightning protection design), the protocol layer compatible with standard industrial Modbus Rtu protocol.
