Document Type and Number:
Japanese Patent JP2015225534
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an analog output circuit reducing a supplies material amount than a conventional one without impairing a current backup function.SOLUTION: An analog output circuit 50A comprises: analog input/output sections 13x and 13y being duplicated and being connected in a transmittable manner between a control unit 1 outputting a command value and a controlled object 2 controlled by an operation signal generated on the basis of the command value; a first diode 51x having an anode connected to an output side of the first analog input/output section 13x and, on the other hand, a cathode connected to an input side of the controlled object; a second diode 51y having an anode connected to an output side of the second analog input/output section 13y and, on the other hand, a cathode connected to a contact point provided between the cathode of the first analog input/output section 13x and the input side of controlled the object; and a first resistor 9 having one end connected to operation signal input sides of the analog input/output sections 13x and 13y and the other end connected to an operation signal output side of the controlled object.
