3-7-5 I/O Signal Noise Prevention
Wiring I/O Units
Whenever possible, place I/O signal lines and power lines in separate ducts or
tubes. If placing them together cannot be avoided, use shielded cable to mini-
mize the effects of noise, and connect the shielded end to the GR terminal.
When an inductive load is connected to an I/O Unit, connect a surge suppressor
or diode in parallel with the load, as shown in the following diagram. The diode
will adsorb the back electromagnetic field generated by the load.
