1) Intelligent building systems were introduced in the United States in the early 1980s as several major technology trends were underway including the emergence of personal computers and innovations in telecommunications.
2) A smart building involves the installation and use of advanced integrated building technology systems to provide actionable information about the building to allow owners and occupants to efficiently manage it.
3) Building automation systems are an example of distributed control systems that use sensors, controllers and networks to automatically control a building's mechanical, lighting and other systems to improve efficiency and occupant experience.

A digital input indicates if a device is turned
on or not. Some examples of a digital input
would be a 24VDC/AC signal, an air
flow switch, or a volta-free relay contact
(Dry Contact).
Analog outputs control the speed or
position of a device, such as a variable
frequency drive, a I-P
(current to pneumatics) transducer, or
a valve or damper actuator. An
example is a hot water valve opening
