Number of Occupied Input/Output Points and Current Consumption

Number of Occupied Input/Output Points and
A.4
Current Consumption
The following tables show how many input/output points are occupied in a base unit by a certain
unit, along with the power supply type and current consumption values needed for selecting a
product.
The current consumption is determined differently in the following cases.
5V DC and internal 24V DC are supplied to the products through an extension cable, and the
current consumption must be calculated
Subtract the current consumption at the internal 24V DC as follows.
– For the AC power type base unit, subtract the current consumption at the internal 24V DC
from the 24V DC service power supply.
– For the DC power type base unit, subtract the current consumption at the internal 24V DC
from the power supply for the internal 24V DC.
– Some special function modules need "external 24 V DC". Include this current in the calcu-
lation of current consumption when the current is supplied by the 24V DC service power
supply. When the current is supplied by an external power supply, the current is not in-
cluded in the calculation of current consumption.
