UniStream Local Expansion Adapter Kit Technical Specifications

This guide provides specifications for Unitronics' Short Range and Long Range Local Expansion Adapter Kits for Uni-I/O™. These kits increase the number of I/Os connected to a single UniStream™ controller 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. Two adapter series are available:

• UAG-XK Series: Compatible with UniStream® controller panels featuring a DIN-rail type structure on the panel rear. The Base unit of a UAG-XK series adapter snaps onto the DIN-rail.
• UAG-CX Series: Compatible with UniStream® controllers that include an I/O Expansion Jack. The Base unit of a UAG-CX series adapter plugs into the jack.

Adapter Models

Power Supply

UniStream controller panels with a CPU-for-Panel can supply power to a maximum of 8 modules, Uni-I/O™ and/or Uni-COM™. Adapters that do not have a power supply draw power from UniStream and supply it to the modules. This means, for example, that if there are 3 modules snapped onto the panel, an additional 5 can be added via this type of adapter.

Adapters with an 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 modules mounted on the panel.

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

Module Support

UniStream™ panels comprising a DIN-rail structure on the panel rear (compatible with UAG-XK)

The number of modules in the next table includes:

• Modules that may be snapped to the rear of the panel.
• Modules linked to the CPU via a Local Expansion Adapter Kit (Uni-I/O modules only).

Note that:

• Any Uni-COM™ modules snapped to the back of the UniStream HMI panel must be connected directly to the CPU-for-Panel or to another Uni-COM module.
• The Base Unit must be plugged into the last element on the back of the UniStream™ HMI Panel. This may be a Uni-COM™ or Uni-I/O™ module.
• If the CPU-for-Panel is the only element plugged onto the back of the HMI Panel, plug the Base unit into it.

Important Note: The Base and End Units of the Short-range and Long-range models look similar but are not interchangeable; do not mix them.

UniStream™ controllers that comprise an I/O Expansion Jack (compatible with UAG-CX)

The number of modules in the next table refers only to the modules connected to the adapter. These controllers lack the DIN-rail structure and cannot be installed with Uni-COM or Uni-I/O.

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 panel + CPU-for-Panel. This includes 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 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).

Daisy-chaining Visualizations

Single Cabinet Configuration: A diagram shows a UniStream controller (CPU I/O) connected to a series of I/O modules. Following these, a UAG-XKPxxxx adapter is connected, leading to more I/O modules (up to 16 units). This setup illustrates local expansion within one cabinet.

Two Cabinets Configuration (Long-range Kit): A diagram depicts two separate cabinets. The first cabinet contains a UniStream controller (CPU I/O) connected to I/O modules, followed by a UAG-XKPxxxx adapter and more I/O modules (up to 16 units). This cabinet is then connected via a "Long-range Kit" (UAG-XKL) to a second cabinet. The second cabinet contains a UAG-XKPxxxx adapter connected to I/O modules (up to 16 units), demonstrating expansion across two cabinets using a long-range adapter.

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 must be followed:

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 of the modules connected directly to the CPU on the back of the HMI Panel. These may be either 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 of the 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 may be either two UAG-XKPxxxx, or one UAG-XKPxxxx and one UAG-XKxxxx.

Configuration Examples

Notes:

1. All examples use the USP-104-B10 10.4″ HMI panel.
2. The amount of modules in all examples relates to Uni-I/O modules. Uni-I/O modules can be mixed 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 illustrates the maximum number of I/O modules connected to a single UniStream™ controller using Uni-I/O modules and 5 Local I/O Expansion adapters with power supplies. The setup shows a CPU I/O unit connected to a series of I/O modules (up to 5 units). This is followed by a UAG-XKPxxxx adapter connected to more I/O modules (up to 16 units). This chain continues with a UAG-XKL (Long Range) adapter, then another UAG-XKPxxxx adapter with I/O modules (up to 16 units), and finally another UAG-XKPxxxx adapter with I/O modules (up to 16 units). This demonstrates a complex daisy-chaining configuration for maximum I/O expansion.

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

A diagram shows a CPU I/O unit connected to I/O modules (up to 5 units). If a UAG-XKxxxx adapter is the only adapter connected to the controller, it is shown connected to the I/O modules, supporting up to 8 modules in total.

If a UAG-XKxxxx follows another adapter with an integrated power supply (e.g., UAG-XKPxxx, UAG-CX-XKPxxx, or UAG-XKLxxxx), 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 illustrates this: a UAG-XKPxxx/UAG-CX-XKPxxx/UAG-XKLxxxx adapter is connected to I/O modules (up to 16 units), which then connects to a UAG-XKxxxx adapter, which in turn connects to I/O modules (up to 8 units).

Daisy-chaining Configuration Summary

The tables below show the possible configurations between two cabinets.

UniStream™ controllers comprising an I/O Expansion Jack

Note that in the case of UniStream™ controllers comprising an I/O Expansion Jack, the UAG-CX-XKPxxx must be used, and it must be the adapter directly connected to the controller.
