MEASURED VALUE OUTPUT DEVICE, MEASURED VALUE MONITOR, CURRENT VALUE OUTPUT DEVICE, AND CURRENT MONITOR

摘要

A current value output device comprises a measuring means such as a current measuring means (11) for measuring the alternating current flowing through the power source line (2) of a motor (1), a sensing circuit (12) for amplifying a measured value such as a measured current value to determine the magnitude of the measured value, a signal conversion section (13) for converting the determined value into a time interval (duration), and an ON/OFF signal output section (14) for sequentially outputting ON/Off signals maintaining an ON state or OFF state for the time interval at every predetermined time, so that the measured value of a motor current in a production line used for monitoring the measured value at every predetermined time is outputted at every predetermined time, as a pulse signal (digital signal) having a pulse width corresponding to the magnitude of the measured value.
