I/O Modules
By adding a variety of I/O and power supply modules, you can use AS-P or Automation Server to tailor the Intelligent Building Management System to your unique requirements.
Power and communications are delivered to the SmartStruxure server device 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 SmartStruxure 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.

Terminal Bases
The terminal bases are used for SmartStruxure 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 SmartStruxure device installed to the right (next terminal base in the chain).

Grounding and Power
It is important to perform the grounding correctly for the following reasons:
To design a safe system that is not harmed by 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.
