Central IO modules UI-8/AO-V-4 and UI-8/AO-V-4-H

Introduction

SpaceLogic* UI-8/AO-V-4 and UI-8/AO-V-4-H Central IO modules are universal input, 8-channel and analog output, 4-channel I/O modules.

The universal inputs are ideal for any mix of temperature, pressure, flow, status points, and similar point types in a building control system.

The universal inputs can be configured to read several different types of inputs:

  • Digital

  • Counter

  • Supervised

  • Voltage

  • Current

  • Temperature

  • Resistive

As counter inputs they are commonly used in energy metering applications. As supervised inputs they are used for security applications where it is critical to know whether or not a wire has been cut or shorted. These events provide a separate indication of alarms and trouble conditions to the system.

The analog outputs are capable of supporting analog voltage point types. Therefore, analog outputs support a wide range of devices, such as actuators.

* Formerly known as SmartX.

Function

Modular and scalable system

The modules are part of a modular system that delivers power and communications on a common bus. Connecting modules is a one-step process: just slide the modules together using the built-in connectors.

Patented two-piece design

Each module can be separated from its terminal base to allow the site to be wired prior to the installation of the electronics. The patented locking mechanism serves as handles for removing the module from its base. All critical components have a protective cover that permits convection cooling to occur.

Two-piece design

Hot-connect and Hot-swap

Because critical applications require 24-hour operation, Schneider Electric designed the Central IO modules for hot-connection of terminal bases and hot-swapping of the modules to their bases. This design ensures continuous power and communication during service operations.

Auto-addressing

The auto-addressing feature helps eliminating the need for setting DIP switches or pressing commission buttons. Each module automatically knows its order in the chain and assigns itself accordingly – significantly reducing engineering and maintenance time.

Simple DIN-rail installation

Fasteners easily snap into a locked position for panel installation. The fastener has a quick-release feature for easy DIN-rail removal.

Efficient terminal management

The Central IO module terminals are clearly labeled and protected by transparent covers. The input and output terminals are at the top and bottom of each module and are accessible for maintenance without removing the module. The EcoStruxure Building Operation WorkStation software can generate custom as-built labels for each module. Pre-perforated letter and A4 size label sheets are available as an accessory.

Accommodates multiple row panel installations

The SpaceLogic devices use built-in connectors for single row connectivity, side by side. If a panel size requires multiple rows, extension cords are available.

LED status indicators

The Central IO module has a status indicator that denotes the health and status of the module.

Each input channel has a dedicated two color status LED. The LED can be configured to display either red or green for each input state.

Hand/Off/Auto switches

The front panel of the UI-8/AO-V-4-H includes Hand/Off/Auto (HOA) switches to provide override control of the analog outputs.

Each output also has a potentiometer to modulate the output signal when the switch is in the Hand position.

The position of the HOA switch is readable through user interfaces, such as the EcoStruxure Building Operation WorkStation software, enabling more precise monitoring and control.

Protection

Protection components on the inputs and the outputs protect against high-voltage short-duration transient events.

The current inputs are protected against over current.

The analog outputs have current limits to protect against permanent short-circuit to ground.

For protection from excess current that could be produced by field wiring, follow these instructions:

  • Connect one RET terminal on each of the Central IO modules to a common chassis/power ground rail in the control panel using a size 16 AWG (1.3 mm 2 ), or larger wire.

  • Individual 24 VDC power sources to the field must be current limited to maximum of 4 A for UL compliant installations, and no more than 6 A in other areas.

  • For more information on wiring, see the SpaceLogic Hardware Reference Guide.
