Precaution when using LED-equipped limit switch
Servicing power supply for input
Use it for input and the expansion FP0 adapter. (Use an external power supply for the FP0 expansion
unit.)
When it is used for another device, confirm the consumption current of the device side before it is
connected. If excess current is being supplied for a long time, the power supply may be damaged.
5.6.2
Output Wiring
Do not connect a load that exceeds the maximum switching ability to the output terminal.
Protective circuit for inductive loads
• With an inductive load, a protective circuit should be installed in parallel with the load.
• When switching DC inductive loads with relay output type, be sure to connect a diode across the ends
of the load.

If the input of PLC does not turn off because of
the leakage current from the LED-equipped limit
switch, the use of a bleeder resistor is
recommended, as shown below.
