3.4.4 Instructions for connecting input devices
As for the details of Instructions for connecting input devices, refer to
the following manual.
→ Refer to FX
Series User's Manual - Hardware Edition.
3G
1) In the case of no-voltage contact:
Fuse
The input current of this PLC is 5 to 7mA/24V DC.
Use input devices applicable to this minute current.
If no-voltage contacts (switches) for large current are used,
contact failure may occur.
24V DC
2) In the case of input device with built-in series diode:
The voltage drop of the series diode should be approx. 4V or
less.
When lead switches with a series LED are used, up to two
switches can be connected in series.
Also make sure that the input current is over the input-sensing
level while the switches are ON.
3) In the case of input device with built-in parallel resistance:
Use a device with a parallel resistance of 15kΩ or more.
When the resistance is less than 15kΩ, connect a bleeder
resistance.
4) In the case of 2-wire proximity switch:
Use a two-wire proximity switch whose leakage current is 1.5mA
or less when the switch is off.
When the current is 1.5mA or more, connect a bleeder
resistance.
