Use the following figure to estimate the maximum cable length relative to the wire size and the load current (in mA) when wiring inputs and outputs.
Note: The following figure applies to
low-voltage (<30V) inputs and outputs only. The required wire size and length for
high-voltage (>30V) Relay Outputs is determined by the load connected to the relay and
local electrical codes.
