Daisy-Chaining: Extending and Expanding I/Os
Up to five Local Expansion Adapters may be chained to each other. The maximum number of I/O
modules that can be connected to a single controller is:
85, for UniStream modular. This includes modules directly connected to the controller.
88, for UniStream PLC. This includes modules directly connected to the controller.
80, for UniStream bulit-in with I/O Expansion Jack.
UniStream can be expanded locally in a single cabinet, using Short range Adapters of up to 3 meters
each (UAG-XKxxxx , UAG-XKPxxxx and UAG-CX-XKPxxxx).
It can also be expanded further to another cabinet, using the Long Range Expansion Adapter
(UAG-XKLxxxx, UAG-CX-XKPLxxxx) as shown in the following drawings:

Daisy-chaining Rules
In order to connect a UniStream™ controller to more than one row of I/O modules via Local I/O
Expansion adapters, you must follow these rules:
UniStream Modular and UniStream PLC
Up to 2 Short-range adapters can be daisy-chained to the controller or to any of the modules that
are connected directly to the controller. These may be either two
UAG-XKPxxxx (that include an integrated power-supply), or one UAG-XKPxxxx and one UAC-
XKxxxx.
When daisy chaining, you can include only 1 Long-range adapter. You may connect it directly to the
controller or to any of the elements that are expanded from it.
UniStream Built-in
Up to 2 Short-range adapters can be daisy-chained to the controller. A UAG-CX-XKPxxx must be
plugged into the jack, and may be followed by a UAG-XKPxxxx or one UAC-XKxxxx.
UniStream™ controllers of all series
Since long range adaptors have integrated power supplies, you may follow any Long-range adapter
by daisy-chaining up to 2 Short range adapters. These may be either two UAG-XKPxxxx, or one
UAG-XKPxxxx and one UAG-XKxxxx.
