The simple temperature control circuit of 555

Published:2011/6/13 21:30:00 Author:Borg | Keyword: temperature control

IC2 is an integrated circuit LM567 of frequency decoding, which consists a frequency decoder with RP1, C3 and so on,and its central frequency f0 is set as the central frequency of audio oscillator at the regulated temperature. When the outside temperature is too low, the difference between the vibration frequency and the regulated central frequency (f0) is noticeable, and LM567 doesn't react to the input signal, and its output terminal is in high LEV, the relay(K) is still. When the outside temperature reaches the regulated value, the central temperatures of IC1 and IC2 are the same, and IC2 decode reliably, the output point of LM567 is in a low LEV, K closes to cut off the power of the controlled equipment.   (View)

Functions and Features M54123 IC is composed of voltage stabling circuit,voltage reference circuit,differential amplifier,lockout and output circuit etc.Its major features are as follows. Firstly,supply voltage range is from 12-28V.Line voltage could work normally when it changes from 120V to 280V,that's to say, leakage circuit can be swtiched off reliably when line voltage is at the low point. Secondly,operation voltage is low(4-9mv),so its zero-sequence current mutual inductor volume is small. Thirdly,leakage operation current is steady becuase there is voltage reference. Fourth,the actual requirements can be meet completely as the operation time less than 0.5s.The Inner Circuit Pane Circuit Diagram of M54123 IC is showed as above.
