Proportion temperature regulator circuit with integrated flip-flop TDAl023

Published:2011/3/22 22:59:00 Author:Jessie | Keyword: Proportion temperature regulator, integrated flip-flop

Proportion temperature regulator circuit with integrated flip-flop TDAl023
This circuit can be used to control the 5℃ to 35℃indoor temperature or other heating equipments. The maximum heating power depends on its thyristor,this one issuitable for 2kW power, and thyristor is BT139. Temperature is controlledby the bridge road which composed by thermistors, resistance R1 and potentiometer Rp, the actual voltage and given voltage respectively adds on the U6 and U9 of integrated flip-flop TDA1023. If the room temperature is far belowthe given temperature,heating machine workswith all the power. If the room temperature is 1K differ from the given temperature,the proportional adjustment will be achieved.   (View)

Sequential timer circuit
Sequential timer circuit

The 556 double timer transports the first half to the latter half by 0.001μF coupling capacitance, giving a total delay which is equal to the sum of single delay. The moment of 6-pin grounding can start the first half of timer. After determining the time interval by 1.1R1C1, the second timer starts delaying, the value is decided by 1.1R2C2.   (View)
