Outline

An input/output powered extension unit is used to expand inputs/outputs.
Power can be supplied to subsequent extension blocks from an input/output powered extension unit with a
built-in 24V DC power supply.
An input/output powered extension unit is required when the capacity of the main unit's built-in power supply
is insufficient for the current consumption demands of the extension blocks.

15.1.1 Product configuration

There are various types of input/output powered extension units. They differ in supply voltage, number of
input/output points, input form, output form and connection type.

15.1.2 Product list

Each model of input/output powered extension unit has a sink and source type and a sink type. If you intend
to add input/output powered extension units, we recommend you to add the same types of units as the main
unit or the sink and source type.
