Abstract:
     The telemetering temp controller with sound alarm consists of op-amp IC, R-S flip-flop, NE555 chip and solid relay. It features small time constant, rapid response, high temp controlling accuracy and good repeatability. It has the functions of measured temp transient display, measured temp preset, audible alarm for upper and lower temp limitation, and on-off temp differential preset. When the TAC 25A 220V solid relay is used, it can directly control an electrothermal load of 220V 25A. The temp controller may be used for thermostatic regulator.
