Number of Input/Output (Occupied) Points and Current Consumption

The following tables show the number of input/output points or the number of input/output occupied points for
each type of device, along with the power supply type and current consumption values needed for selecting a
product.
• Number of input/output points or input/output occupied points on each type of device
• Output current of 24V DC service power supply of main units
• Output current of 5V DC power supply and 24V DC service power supply of input/output powered
extension units
• Current consumed by input/output extension blocks and special function blocks
The current consumption is determined differently in the following cases.
• In the input/output powered extension unit, 5V DC and internal 24V DC are supplied via extension cables.It
is necessary to calculate the current consumption.Subtract the current consumption of the internal 24V DC
from the 24V DC service power supply.
• The special function units/blocks connected to the AC power type main unit or to the 24V DC service
power supply terminal of the input/output powered extension unit consume the external 24V DC. Include
the current in the calculation of current consumption.
When the terminal is connected with an external power supply, the current is not included in the calculation
of current consumption.
