The allowable currents for cables and connectors are given below.
Select the communications cable so that the total current consumption of all
Slave Units does not exceed the allowable current of the cable.
There are limits to the allowable current for the communications power supply
connectors on the Master Unit and Repeater Units, Flat Connector Sockets,
and Flat Connector Plugs. Do not allow the current flow where these connec-
tors are used to exceed the allowable current.
The voltage drop must be considered so that the power supply voltage at the
Slave Unit that is the farthest from the power supply will still be within the
allowable power supply range.
The voltage drop is expressed by the following formula.
If the voltage drop is too large and power cannot be supplied to the farthest
Slave Unit within the allowable range, add a Repeater Unit and supply power
from the Repeater Unit.
