Instructions for connecting input devices

1) In the case of no-voltage contact:
The input current of this PLC is 5 to 7 mA/24 V DC.
Use input devices applicable to this minute current.
Fuse
If no-voltage contacts (switches) for large current are used,
contact failure may occur.

2) In the case of input device with built-in series diode:
3-wire type
sensor The voltage drop of the series diode should be approx. 4 V 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 having a parallel resistance, Rp, of 15 kor more.
Fuse
When the resistance is less than 15 k, connect a bleeder
resistance, Rb, obtained from the formula as shown in the

4) In the case of 2-wire proximity switch:
Use a two-wire proximity switch whose leakage current,
1.5 mA or less when the switch is off.
When the current is 1.5 mA or more, connect a bleeder
resistance, Rb, obtained from formula as shown in the following
figure.
