Power supply
(24 VDC)
Supplying I/O power from multiple power supplies instead of from one power
supply enables reducing the line current, reducing the voltage drop, and
decreasing the size of the cable. Using multiple power supplies should also be
considered to increase system safety when power supply errors occur.
The location of power supplies and the grouping of Slave Units should be con-
sidered based on whether the overall system is to be stopped when a power
supply error occurs.
If it is necessary to prevent the overall system from stopping to ensure system
safety, consider placing power supplies in more than one location and con-
sider the way Slave Units should be grouped when supplying power.
Also consider the power supply methods in light of the total cost, including the
following items:
The capacity and number of power supplies, Cable thickness (allowable cur-
rent) and length (voltage drop), System safety, and Wiring work.
