3.2 Output Module
3.2 Output Module
(1) Common precautions for all output modules
(a) Maximum switching frequency when the module drives Inductive load.
The output must be on for one second or longer and off for one second or longer.
(b) Load for connection
When connecting a counter or timer that has a DC-DC converter as a load, select an output module whose
maximum load current is larger than inrush current of the load.
Selecting an output module by average current of the load may cause a failure of the module because inrush
current flows at a constant frequency at power-on or during operation due to the connected load.
If an output module needs to be selected by average current of the load, take either of the following actions to
reduce an influence from inrush current.
Connecting a resistor to the load in series
Connecting an inductor to the load in series
