If the signal lines and power lines cannot be routed in separate ducts, use shielded cable. Connect
the shield to the ground terminal at the Controller, and leave it unconnected at the input device.
Wire the lines so that common impedance does not occur.
Such wiring will increase the number of wires, so use common return circuits.
Use thick wires with sufficient allowance for the return circuits, and bundle them with lines of the
same signal level.
For long I/O lines, wire the input and output signal lines separately.
Use twisted-pair wires for pilot lamps (and particularly lamps with filaments).
Use countermeasures, such as CR surge absorbers and diodes, for input device and output load
device noise sources, as required.
External Wiring
Wiring, and noise countermeasures in particular, are based on experience, and it is necessary to
closely manage wiring based on experience and information in the manuals.
Wiring Routes
Each of the following combinations includes different signal types, properties, or levels. They will
cause the signal-to-noise ratio to drop due to factors such as electrical induction. As a general rule
when wiring, either use separate cables or separate wiring routes for these items. Future mainte-
nance operations and changes to the system will also be made easier by carefully organizing the
wiring from the start.
Power lines and signal lines
Input signals and output signals
Analog signals and digital signals
High-level signals and low-level signals
Communications lines and power lines
DC signals and AC signals
High-frequency devices (such as Inverters) and signal lines (communications)
Wiring
Observe the following points when wiring power supply and signal cables.
When routing signal cables with differing characteristics through the same duct, always keep
them separated.
As much as possible, avoid routing multiple power supply lines through the same duct.
If it cannot be avoided, then construct a partition between them in the duct and ground the parti-
tion.
