HVAC SEQUENCER

An HVAC sequencer is a small circuit designed to help stabilize circuits and turn switches on and off quickly in an electrical setting. The sequencers are designed to stage the different parts of the electrical equipment so that the appliance does not overload and break the circuits. Many products use the HVAC sequencers to keep engines and other mechanical devices from overheating or exploding.
Identification
An HVAC sequencer is identified by its unique size and shape. Depending on the size of the final product, the sequencers can be different sizes as well. There are usually two different segments to an HVAC sequencer, and they are attached together by a smaller middle piece. They are constructed of tough metal and are usually heavy. HVAC sequencer can be used in things such as electric pumps, furnaces, and motors.
Features
Each type of HVAC sequencer has its own set of features. Some of the most common features, however, are shared among many different kinds of HVAC sequencers. Some common features are the ability to have a few seconds delay between sequences, several different mounting positions, the ability to resist shocks and vibrations, and 24-volt input control. HVAC sequencers are designed for several different kinds of tasks, which makes them have versatility in the features that they offer.
