Concept
I/O Modules
By adding a variety of I/O and power supply modules, you can use the SmartX AS-P server to tailor the Intelligent Building Management System to your unique requirements.
Power and communications are delivered to the SmartX server and its family of I/O modules in a common bus, thus allowing them to be plugged together without tools. This simple one-step process involves sliding the modules together using their built-in connectors.
The available I/O modules are designed to accommodate a fixed number of inputs and outputs. For example, several I/O modules, such as digital inputs, only support a single electrical type. Other modules, such as digital inputs mixed with digital outputs, support a combination of electrical types. The various modules enable you to select the right combination of points necessary for your project.
The I/O modules are based on the patented two-piece design. Each I/O module consists of an electronics module and a terminal base.
Electronics Modules
The electronics module is the main component of SmartX devices that are based on the patented two-piece design. The electronics module is installed on a terminal base, which constitutes the second component of the device.
For more information, see Electronics Modules .
Terminal Bases
The terminal bases are used for SmartX devices that are based on the patented two-piece design. The terminal base provides the I/O bus to the electronics module installed on the terminal base as well as to the SmartX device installed to the right (next terminal base in the chain).
For more information, see Terminal Bases .
I/O Module LEDs
The I/O modules have the following status indicator LEDs on the front of the module:
I/O Module Status LED
I/O Channel Status LEDs
For more information, see I/O Module LEDs .
Override Switches and Potentiometers
For I/O modules with outputs, the following components on the front provide control of the output channels:
Override switches
Potentiometers
For more information, see Override Switches and Potentiometers .
Important Information on Central IO Modules with Manufacturing Date Earlier Than 2021-W26
The override switches on Central IO modules with manufacturing date earlier than 2021-W26 must be disabled to remove the risk of an improper output. To disable the override switches, update the Central IO module firmware to version 2.017 or later.
For more information, see Important Information on Central IO Modules with Manufacturing Date Earlier Than 2021-W26 .
External Device Connections
There are many different kinds of external devices from different vendors that can be connected to an EcoStruxure BMS.
For more information, see External Device Connections .
Grounding and Power
It is important to perform the grounding correctly for the following reasons:
To design a system that is not harmed by detected minor connection errors.
To design a system that works well and is resistant to EMI.
To minimize the effects of ground currents that can cause unstable measurements.
For more information, see Grounding and Power .
Input Modules
Input modules support a single electrical type, such as digital or universal inputs. The available input modules include the following:
DI-16
UI-16
RTD-DI-16
For more information, see Input Modules .
Output Modules
Output modules support a number of electrical types, such as digital, tristate, and pulsed digital outputs. The available output modules include the following:
DO-FA-12 and DO-FA-12-H
DO-FC-8 and DO-FC-8-H
AO-8 and AO-8-H
AO-V-8 and AO-V-8-H
For more information, see Output Modules .
Mixed Modules
Mixed modules support a combination of electrical types, such as universal inputs mixed with digital outputs. The available mixed modules include the following:
UI-8/DO-FC-4 and UI-8/DOFC-4-H
UI-8/AO-4 and UI-8/AO-4-H
UI-8/AO-V-4 and UI-8/AO-V-4-H
