Selecting the control cables



Shielding

All control cables must be shielded.
Use a double-shielded twisted pair cable (figure a below) for analog signals. Employ
one individually shielded pair for each signal. Do not use common return for different
analog signals.
A double-shielded cable is the best alternative for low-voltage digital signals but
single-shielded (b) twisted pair cable is also acceptable.


Signals in separate cables

Run analog and digital signals in separate, shielded cables.
Do not mix 24 V AC/DC and 115/230 V AC signals in the same cable.


Signals allowed to be run in the same cable

Relay-controlled signals, providing their voltage does not exceed 48 V, can be run in
the same cables as digital input signals. The relay-controlled signals should be run as
twisted pairs.
