Device for coupling a burner ventilator to a microprocessor

摘要

The device (10) has a voltage terminal (13) at which relatively high voltage lies for providing a logical voltage control signal for a gas burner ventilator. Relatively low voltage lies at another voltage terminal (14) for providing current control signal to the gas burner ventilator. The former voltage terminal is coupled with an output-sided terminal (12) by interconnection of a resistor (15). The latter voltage terminal is coupled with the output-sided terminal by interconnection of a series circuit made of another resistor (16) and a diode (17).
