I/O Unit Wiring Precautions
The following diagram shows two methods that can be used to reduce the
large inrush current caused by certain loads, such as incandescent light
bulbs.
Be careful not to damage the output transistor.
Whenever possible, place I/O signal lines and power lines in separate ducts or
raceways both inside and outside of the control panel.
If the I/O wiring and power wiring must be routed in the same duct, use
shielded cable and connect the shield to the GR terminal to reduce noise.
When an inductive load is connected to an I/O Unit, connect a surge suppres-
sor or diode in parallel with the load as shown below.
