The following table defines cable length guidelines for the various wire sizes that may be used for wiring low-voltage (<30 V) input and outputs.

Table 1. Cable length guidelines
Guideline Wire size/gauge and type Maximum cable length and type Assumptions

A

1.0 mm (18 AWG) stranded copper

457 m (1,500 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.

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

0.5 mm (24 AWG) stranded copper

107 m (350 ft) twisted wire

B

1.0 mm (18 AWG) stranded copper

229 m (750 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.

0.8 mm (20 AWG) stranded copper

137 m (450 ft) twisted wire

0.6 mm (22 AWG) stranded copper

91 m (300 ft) twisted wire

0.5 mm (24 AWG) stranded copper

61 m (200 ft) twisted wire

C

See Figure 1 to select wire size/gauge. Use stranded copper wire.

See Figure 1 to determine cable length. Use twisted wire cable.
