Abstract
PURPOSE:To reduce power consumption and to employ two output terminals by constituting an input/output isolation relay in such a way that a current discrimination section outputs a closing signal and an opening signal to a transistor(TR) from a power supply of an output DC power supply. CONSTITUTION:A signal output section 10 of a relay 11 consists of a resistor R12 being a current detection section and a switch section 10a. The resistor R12 detects a signal voltage V is response to a current detected between terminals 4 and 5. The switch section 10a consists of each section except the resistor R12 to block the current flowing between the terminals 4, 5 by an input of an opening signal turning off a transistor(TR) T4. Then the current flowing is attained by the input of a closing signal turning on the TR T4. A current discrimination section 9 outputs a closing signal or an opening signal in response to discrimination whether or not a load conduction current I is in the overcurrent state. Moreover, current discrimination section 9 outputs a closing signal and an open signal by supplying power to a photo TR 6b, output terminal 4, 5 and a load L from a power supply Eout. Thus, two output terminals 4, 5 are enough for the output terminals.
