たことを特徴とする中継回路。In a relay circuit that uses an input signal voltage to drive a relay and uses the relay contact of the relay as a contact output, the input signal voltage is applied to the relay via a parallel circuit of a capacitor and a resistor, and when the input signal voltage rises, the capacitor Set the capacitance value of the capacitor so that the current flowing through the resistor is larger than the relay's current, and so that the current flowing through the resistor when the input signal voltage is steady is slightly larger than the minimum holding current of the relay. A relay circuit characterized in that a resistance value of a resistor is set.
