Abstract

As a configuration for detecting an occurrence of abnormalities such as a disconnection of output wiring or an overcurrent of a PLC analog output module that controls a load by an analog current signal, the PLC analog output module includes a current output circuit that outputs the analog current signal, a current sensing resistor provided at a current output terminal of the current output circuit for directly detecting an analog current output to the load, a monitoring circuit that monitors voltages at both ends of the current sensing resistor, and an abnormality detection circuit that discriminates whether there is an occurrence of a disconnection or an overcurrent based on a monitoring result of the monitoring circuit.
