SEQUENCER ANALOG OUTPUT UNIT

摘要

As a configuration for detecting the occurrence of malfunctions such as disconnection or overcurrent output in the output wiring of a sequencer analog output unit in which load is controlled by an analog current signal, provided is a sequencer analog output unit in which load is controlled by an analog current signal, wherein a current detection resistor that directly detects analog current output to the load is disposed at a current output terminal of a current output circuit that outputs the analog current signal, and a monitor circuit that monitors both terminal voltages of the current detection resistor and a malfunction detection circuit that can determine whether or not disconnection or overcurrent is occurring on the basis of the monitoring results of the monitor circuit are provided.
