Note
When an inductive load is connected to I/O, connect a surge suppressor or
diode in parallel with the load as shown below.
Use surge suppressors and diodes with the following specifications.
Observe the following precautions for I/O wiring, power supply wiring, and
power line wiring.
Resistor: 50 Ω
Capacitor: 0.47 µF
Voltage: 200 V
Surge suppressor specifications
• When multi-conductor signal cable is being used, do not combine I/O
• If wiring racks are parallel, allow at least 300 mm between the racks.
• If the I/O wiring and power cables must be placed in the same duct, they
wires and other control wires in the same cable.
must be shielded from each other using grounded steel sheet metal.
