1) Power supply voltage: DC6.0V~30V;2) Temperature control range: 40 ~1103) Temperature control accuracy: 0.14) Measurement input: NTC10K length of 0.5 m, waterproof type, support for 18B20 digital sensor access5) Refresh frequency: 1 second; Output type: 10A relay output (relay is equivalent to switch, only switch and cannot outputvoltage)material: plasticColor as shownProduct function description2.1Heating mode (H)When Detect_Temperature (current temperature) Set_TemperatureBacklash _Temperature , the relay leads on and the heating equipment starts working;When Detect_Temperature (current temperature) sets the temperature, the relay is disconnected and the heating device stops working;Example: Set_Temperature 30 , Backlash_Temperature 5When the temperature is 20 25 (30 5 = 25), the relay suction s to heating, when the temperature reaches 30 Set_Temperature 30 , the relay is disconnected and the heating is stopped;2.2Refrigeration mode (C)When Detect_Temperature (current temperature) Set_Temperature + Backlash _Temperature , the relay is turned on and the refrigeration equipment starts working;When Detect_Temperature (current temperature) Set_Temperature , the relay is disconnected and the refrigeration equipme nt stops working;Example: Set_Temperature 30 , Backlash_Temperature 5When the temperature is 36 35 (30 + 5 = 35), the relay suction starts to cool, and when the temperature reaches 30 Set_Temperature 30 , the relay is disconnected and the cooling is stoppedPackage Contents:1 x Temperature ControllerOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
