PROBLEM TO BE SOLVED: To provide an analog signal output device capable of adjusting an analog signal to be output, without removing its chassis. SOLUTION: The analog signal output device which varies a zero point and a span of the analog signal to be output on the basis of a varying instruction, includes: an operation unit which is exposed outside and receives various operational instructions; and a control unit which varies the zero point of the analog signal to be output on the basis of a zero-point varying instruction, when the operation unit receives the zero-point varying instruction, and which varies the span of the analog signal to be output on the basis of a span varying instruction and stores a span value representing the varied span, when the operation unit receives the span varying instruction, and which then computes an output value of the analog signal on the basis of the zero point and the span value.
