This guide provides specifications for Unitronics' Short Range and Long Range Local Expansion Adapter Kit for Uni-I/O™. These kits increase the number of I/Os connected to a single UniStream™ by linking it to an additional row of Uni-I/O™ modules. All Local Expansion Adapter Kits include a Base unit, an End unit, and a connecting cable.
Power Supply
UniStream controller panels and CPU-for-Panel can supply power to a maximum of 8 modules (Uni-I/O™ and/or Uni-COM™). Adapters without a power supply draw power from UniStream and supply it to the modules. For example, if 3 modules are snapped onto the panel, an additional 5 can be added via this type of adapter.
Adapters with integrated power supply must be connected to a 24VDC power source. These adapters can then supply up to 16 modules with power, regardless of any mounted on the panel.
Installation Guides are available in the Unitronics Technical Library at www.unitronics.com.
Daisy-Chaining: Extending and Expanding I/Os
Up to five Local Expansion Adapters may be chained. The maximum number of I/O modules connected to a single controller is:
- 85, for UniStream panel + CPU-for-Panel (including modules snapped to the panel's rear).
- 80, for UniStream™ controllers with I/O Expansion Jack.
UniStream can be expanded locally in a single cabinet using Short range Adapters (UAG-XKxxxx, UAG-XKPxxxx, UAG-CX-XKPxxxx) up to 3 meters each. Further expansion to another cabinet is possible using the Long Range Expansion Adapter (UAG-XKLxxxx).
Diagram Description: Single Cabinet vs. Two Cabinets Configuration
The diagram illustrates two primary configurations for UniStream I/O expansion. The "Single Cabinet" setup shows a UniStream CPU/I/O unit connected to a UAG-XKPxxxx adapter, which then connects to multiple I/O modules. This represents a compact, localized expansion. The "Two Cabinets" setup depicts a more extensive system. It starts with a UniStream CPU/I/O unit in one cabinet, connected to a UAG-XKPxxxx adapter and I/O modules. A UAG-XKL (Long-range Kit) then extends the connection to a second cabinet, where it connects to another UAG-XKPxxxx adapter and additional I/O modules. This highlights the capability for distributed I/O expansion across different physical locations or enclosures.
Daisy-chaining Rules
To connect a UniStream™ controller to more than one row of I/O modules via Local I/O Expansion adapters, the following rules apply:
UniStream™ comprising a DIN-rail structure (compatible with UAG-XK)
- Up to 2 Short-range adapters can be daisy-chained to the CPU-for-Panel or to any modules connected directly to the CPU on the back of the HMI Panel. These can be two UAG-XKPxxxx (with 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 CPU-for-Panel or to any elements expanded from it.
UniStream™ controllers comprising an I/O Expansion Jack (compatible with UAG-CX)
- 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 both series
- Since long range adapters have integrated power supplies, any Long-range adapter may be followed by daisy-chaining up to 2 Short range adapters. These can be 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 in all examples relate to Uni-I/O modules. Uni-I/O modules can be mixed with Uni-I/O Wide modules, where 1 Uni-I/O Wide module equals 1.5 Uni-I/O modules.
Configuring for maximum I/Os
Diagram Description: Maximum I/O Configuration with 5 Local I/O Expansion Adapters
This complex diagram illustrates the maximum number of I/O modules connectable to a single UniStream™ controller using Uni-I/O modules and five Local I/O Expansion adapters with power supplies. The configuration shows a central CPU I/O unit. From this unit, a chain extends: first to a UAG-XKPxxxx adapter (supporting up to 5 units), then to another UAG-XKPxxxx (up to 16 units), and finally to a third UAG-XKPxxxx (up to 16 units). A separate branch from the CPU I/O unit shows a UAG-XKL (Long-range) adapter, which then connects to a UAG-XKPxxxx (up to 16 units) and another UAG-XKPxxxx (up to 16 units). This setup demonstrates a highly expanded system with multiple daisy-chained adapters to maximize I/O capacity.
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.
Diagram Description: UAG-XKxxxx as Sole Adapter
This diagram shows a UniStream CPU I/O unit directly connected to a UAG-XKxxxx adapter, which then connects to a series of I/O modules. This configuration supports up to 8 I/O modules in total, with the UAG-XKxxxx acting as the single expansion point without an integrated power supply.
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.
Diagram Description: UAG-XKxxxx Following a Powered Adapter
This diagram illustrates a configuration where a UAG-XKxxxx adapter is preceded by a powered adapter. It shows a UAG-XKPxxx, UAG-CX-XKPxxx, or UAG-XKLxxxx adapter connected to a UniStream CPU I/O unit. This powered adapter then connects to a UAG-XKxxxx adapter, which in turn connects to I/O modules. The powered adapter supports up to 16 units, while the subsequent UAG-XKxxxx adapter supports up to 8 units, demonstrating how a non-powered adapter can extend a powered chain.
