1) Power supply voltage: DC6.0V~30V; 2) Temperature control range: 40 ~110 3) Temperature control accuracy: 0.1 4) Measurement input: NTC10K length of 0.5 m, waterproof type, support for 18B20 digital sensor access 5) Refresh frequency: 1 second; Output type: 10A relay output (relay is equivalent to switch, only switch and cannot outputvoltage) material: plastic Color as shown Product function description 2.1 Heating mode (H) When Detect_Temperature (current temperature) Set_Temperature Backlash _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 5 When 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; 2.2 Refrigeration 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 5 When 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 stopped Package Contents: 1 x Temperature Controller Only the above package content, other products 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.
