Precaution when Using LED-equipped Lead Switch
When an LED is connected in series to an input contact such as an LED-equipped lead switch,
make sure that the voltage applied to the PLC input terminal is greater than the ON voltage. In
particular, take care when connecting a number of switches in series.
■
Precaution when Using Two-wire Type Sensor
If input to the PLC does not turn off because of leakage current from a two-wire type
photoelectric sensor or a proximity sensor, connecting a bleeder resistor is recommended, as
shown below.
■
Precaution when Using LED-equipped Limit Switch
If the input of PLC does not turn off because of leakage current from the LED-equipped limit
switch, the use of a bleeder resistor is recommended, as shown below.

3.2.3 Output Wiring

The following figures show the case when they are connected with the sink output.

Protective circuit for inductive loads
With an inductive load, a protective circuit should be installed in parallel with the load.
