Output adjustment device of analog output module

Abstract

Some embodiments include an output adjustment device of an analog output module so as to verify a normal operation of an analog output module for use in a programmable logic controller (PLC). The output adjustment device of an analog output module may include: a microprocessor unit (MPU) performing an arithmetic operation on a digital signal, an analog output module including an analog signal output unit receiving a signal output from the MPU to output an analog signal, and an output signal adjustment unit outputting a control signal for controlling a magnitude or amplitude of the output analog signal to the MPU.
