Assumptions
1.0 mm (18 AWG) stranded
copper
457 m (1,500 ft)
twisted wire
0.8 mm (20 AWG) stranded
copper
297 m (975 ft)
twisted wire
0.6 mm (22 AWG) stranded
copper
183 m (600 ft)
twisted wire
A
0.5 mm (24 AWG) stranded
copper
107 m (350 ft)
twisted wire
100 mV maximum voltage drop
Depending on cable and the
connected input or output device,
you may have to define an offset
in the setup software for the input
or output point.

C See Figure 8 to select wire
size/gauge. Use stranded
copper wire
See Figure 8 to
determine cable
length. Use twisted
wire cable.
N/A
Maximum cable length versus load current
Use Figure 8 to estimate the maximum cable length relative to the wire size and the load current (in
mA) when wiring inputs and outputs.
Note: Figure 8 applies to low-voltage (<30 V) inputs and outputs only.
