"Do you have a list of building automation abbreviations" is a common request we get here at Smart Buildings Academy.
This guide will continue to grow every week as we add more and more definitions to the guide. If you have a suggestion for an acronym please post it in the comments. Please be aware this list is a work in progress.

A control device that enables the building automation controller to change the state of dampers and valves by converting electrical energy into torque (usually measured in foot lbs). Actuators accept control signals from the building automation controller and power from transformers.

Amperage, also known as current, is the measurement of the flow electricity across a wire. Current is calculated by volts / resistance. Essentially as the resistance increases you will get more current. Current produces heat (which on a side note is how electric heating works). Also, we use current for long distance control signals because it is not as affected by distance and interference.
