UniStream® Technical Specifications: Local Expansion Adapter Kits

This guide provides specifications for Unitronics' Short Range and Long Range Local Expansion Adapter Kit for Uni-I/O™.

All Kits comprise a Base unit, an End unit, and a connecting cable. The cable length varies according to kit model.

Short-range adapter Kits: Up to 3 meters
Long-range adapter Kits: 3 meters and up

Kits whose models contain the letter 'P' include a built-in power supply; a powered adapter module supports a greater number of I/O modules.

There are two main classes of adapters:

UAG-XK

Both the Base and End units of these adapters have DIN-rail clips. Users can:

Snap the base onto the DIN-rail type structure on the back of UniStream Modular HMI
Snap the base directly onto a UniStream PLC

UAG-CX

The base unit of these adapters has a plug; the end unit has DIN-rail clips. Users can plug the base unit only into the I/O Expansion Jack offered by the UniStream Built-in series.

Note that the maximum number of modules supported by a single controller is provided in the controller's technical specifications.

Technical specifications are available in the Unitronics Technical Library at www.unitronicsplc.com.

Adapter Models

The 'x's in the model numbers are placeholders for the cable lengths.

Model	Installation Options	Integrated Power Supply	Module Support
UAG-XKxxx	DIN-rail structure	No	8, includes any modules directly connected to a controller
UAG-XKPxxx	DIN-rail	Yes	16
UAG-XKPLxxxx		Yes	16, in addition to any modules directly connected to a controller
UAG-CX-XKPxxx	Plug into controller Jack	Yes	16
UAG-CX-XKPLxxxx		Yes	16

Power Supply

Adapters without an integrated power supply: UniStream Modular and UniStream PLC controllers can supply power to a maximum of 8 modules. Adapters that do not have a power supply draw power from UniStream and supply it to the modules. For example, if there are 3 modules directly connected to the controller, an additional 5 can be added via this type of adapter.
Adapters with integrated power supply: Must be connected to a 24VDC power source. The adapter can then supply up to 16 modules with power, regardless of any directly connected to the controller.

Installation Guides are available in the Unitronics Technical Library at www.unitronicsplc.com.

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 built-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 descriptions:

Single Cabinet Configuration

A diagram depicts a single cabinet setup. It shows a CPU connected to I/O modules, followed by a UAG-XKPxxxx adapter, then more I/O modules, and another UAG-XKPxxxx adapter, extending up to 5 units. This configuration supports up to 16 units of I/O modules. Another line shows a UAG-XKL adapter connected to I/O modules, supporting up to 16 units.

Two Cabinets Configuration (Long-range Kit)

A diagram illustrates two cabinets connected by a long-range kit. The first cabinet contains a CPU connected to I/O modules, followed by a UAG-XKPxxxx adapter, then more I/O modules, extending up to 16 units. This cabinet is connected via a long-range kit to a second cabinet, which also contains a UAG-XKPxxxx adapter and I/O modules, supporting up to 16 units.

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, the following rules must be followed:

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 UAG-XKxxxx.
When daisy chaining, only 1 Long-range adapter can be included. It may be connected 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 UAG-XKxxxx.
UniStream™ controllers of all series: Since long range adaptors have integrated power supplies, any Long-range adapter may be followed by daisy-chaining up to 2 Short range adapters. These may be either two UAG-XKPxxxx, or one UAG-XKPxxxx and one UAG-XKxxxx.

Configuration Examples

Notes:

All examples use the USP-104-B10 10.4″ HMI panel.
The amount of modules at all examples relate to Uni-I/O modules. Users can mix Uni-I/O modules with Uni-I/O Wide modules, considering that 1 Uni-I/O Wide module equals 1½ Uni-I/O module.

Configuring for maximum I/Os

A diagram shows the greatest number of I/O modules that can be connected to a single UniStream™ controller using Uni-I/O modules and 5 Local I/O Expansion adapters with power supplies. The top row shows a CPU connected to I/O modules (up to 5 units), followed by a UAG-XKPxxxx adapter and I/O modules (up to 16 units), and another UAG-XKPxxxx adapter and I/O modules (up to 16 units). The bottom row shows a UAG-XKL adapter connected to I/O modules (up to 16 units), followed by a UAG-XKPxxxx adapter and I/O modules (up to 16 units), and another UAG-XKPxxxx adapter and I/O modules (up to 16 units).

Configurations with Short-range adapter, no Power Supply (UAG-XKxxxx)

If UAG-XKxxxx is the only adapter connected to the controller, the system can support up to 8 modules.

A diagram illustrates a CPU connected to I/O modules (up to 5 units), followed by a UAG-XKxxxx adapter and I/O modules (up to 8 units).

If a UAG-XKxxxx follows another adapter with an integrated power supply, the support capacity of that powered module limits the number of Uni-I/Os that can be connected to the UAG-XKxxxx; in any event, no more than 8 Uni-I/Os can follow a UAG-XKxxxx adapter.

A diagram shows a UAG-XKPxxx, UAG-CX-XKPxxx, or UAG-XKLxxxx adapter connected to I/O modules (up to 16 units), followed by a UAG-XKxxxx adapter and I/O modules (up to 8 units).

This example combines all types of adapters:

A complex diagram illustrates various combinations. The top row shows a CPU connected to I/O modules (up to 5 units), followed by a UAG-XKPxxxx adapter and I/O modules (up to 16 units), then a UAG-XKxxxx adapter and I/O modules (up to 8 units), and finally another UAG-XKPxxxx adapter and I/O modules (up to 16 units). The bottom row shows a UAG-XKL adapter connected to I/O modules (up to 16 units), followed by a UAG-XKxxxx adapter and I/O modules (up to 8 units), and then a UAG-XKPxxxx adapter and I/O modules (up to 16 units).
