12.8 PLSY / Pulse Y Output
6. Handling of pulse output terminals in the main units
The outputs Y000 and Y001 are the high speed
response type.
When using a pulse output instruction or
positioning instruction, adjust the load current of
the open collector transistor output.
When the load is smaller, connect a dummy
resistor in parallel to the outside of a used output
terminal (Y000 or Y001) as shown in the circuit
diagram below so that the specified current shown
below flows in the output transistor.

4) For FX
1S and FX1N PLCs
Even without connecting a dummy resistor, a pulse output of 100 kHz or less can be generated under 5 to
24 VDC (10 to 100 mA).
5) For FX
0S, FX0, FX0N, FXU and FX2C PLCs
Have a current of about 100 mA flow for the FX
2C PLC and a current of about 200 mA flow for the FX0S,
FX
0, FX0N and FXU PLCs and extension.
