Abstract
PURPOSE: To commonly use both a proportional control circuit and a sequence control circuit at constant voltage circuit or the like to reduce the number of circuit elements by connecting a low voltage portion and a high voltage portion in a proportional control circuit portion through a phototransistor.
CONSTITUTION: A proportional combustion control device consists of a sequence control circuit 3 for controlling automatically the sequence of the on or off of the burner combustion and a proportional control circuit 1 for proportionally controlling the load current flown to high load 2 such as blower motor or the like. In this case, a low voltage portion 20 having a temperature sensor 5 and an amplifier circuit 6 in the circuit 1 is connected to the high voltage portion of the load current limiter circuit 7 through a phototransistor 19 for electrically insulating it. According to this configuration, the ground of the low voltage portion 20 is commonly used to the ground G of the control circuit 3, and a constant-voltage circuit 12 can be commonly used as the constant-voltage circuit of the low voltage portion 20 to as to reduce the number of circuit elements as compared with the conventional one.
