Short-Range Local Expansion Kit
Installation Guide
UAG-XKxxx
Use a Short-Range Local Expansion Kit to expand your I/O configuration by connecting a
UniStream™ CPU controller to Uni-I/O™ modules located on a DIN-rail.
Short-Range Local Expansion Kits are available:
Without power supply
With power supply
This enables a single CPU to support a greater
number of modules
The kit is available with cables of differe nt le ng ths.
Note that the maximum number of modules supporte d
by a single CPU is provided in the CPU’s technic al
specifications.

Installation Space Considerations
Allocate space for the B a se Unit and End Unit according to the dimens ions in the kit’ s
technical specifica tio ns . A l so, cons ider the space required to install and connect them, as
shown in the following Ins talla tio n ins tructions.
Turn off syste m power before conne c ting or disconnecting any modules or devices.
Use proper precautions to prevent Ele c tro -Static Discharge (ESD).
This kit enables you to connect a UniStream™ controller to a row of Uni-I/O™ modules
located on a DIN-rail. To do this, you must:
Connect the Base Unit to the last device installe d on the back of the HMI panel. This may
be the CPU-for-Panel, a Uni-COM™ module, or another Uni-I/O™ module.
Connect the End Unit to the first module in a row of Uni-I/O™ modules.
Link the End Unit into the Base Unit via the connecting c able.
If you are using a:
UAG-XKPxxx with power supply, connect it to a power source
UAG-XKxxx without power supply, earth it.
