In addition to the wiring guidelines in
, observe these guidelines when wiring NIE inputs and outputs:
•
Run
all
low-voltage wiring and cables separate from high-voltage wiring.
•
All input and output cables, regardless of wire size or number of wires, should consist of stranded, insulated,
and twisted copper wires.
•
Shielded cable is not required for input or output cables.
•
Shielded cable is recommended for input and output cables that are exposed to high electromagnetic or radio
frequency noise.
Inputs/outputs with cable runs under 30 m (100 ft) typically do not require an offset in the software setup. Cable runs
over 30 m (100 ft) may require an offset in the input/output software setup.
defines cable length guidelines for the various wire sizes that may be used for input and output wiring.
Maximum Cable Length versus Load Current
Use
to estimate the maximum cable length relative to the wire size and the load current (in mA) when
wiring inputs and outputs.
FC and SA Bus and Supply Power Wiring Guidelines
provides information about the functions, ratings, and requirements for the NIE communication bus and
supply power terminals, and guidelines for wire sizes, cable types, and cable lengths when wiring the NCE
communication buses and supply power.
In addition to the guidelines in
, observe these guidelines when wiring the SA/FC Buses and supply power:
•
Run all low-voltage wiring and cables separate from high-voltage wiring.
•
All FC and SA Bus cables, regardless of wire size, should be twisted, insulated, stranded copper wire.
•
Shielded cable is strongly recommended for all FC and SA Bus cables.
•
Refer to the
MS/TP Communications Bus Technical Bulletin (LIT-12011034)
for detailed information regarding
wire size and cable length requirements for the FC and SA buses.
