Electromechanical Relays
When it comes to
electrical contacts into other contacts by either interrupting or ending a circuit. Still confused? Don't worry we have the break down on this semiconductor.
How Do Relays Work?
In order for a relay to do its job, there must be two circuits:
contact (relay side) and energizing. Once the relay coil experiences a kick start, a magnetic field will be created when current flows through the coil. Wondering if a DC or AC current matters in a relay's energized flow? It doesn't. This is due to the fact that relays are constructed for particular applications to avoid problems.
Types of Relays
* '''
directs current between two amps and 30 amps.
* '''
solenoids (a coil of wire that can either control magnetic fields or change energy to linear motion) are converted or transferred with the help of reed relays.
* '''Aerospace''': Unless you work for the military or NASA then you should know that an aerospace relay, also called a MIL-spec relay, are used in planes, helicopters, vehicles, etc. These relays all meet military specifications.
Although relays must be connected to a semiconductor or circuit, they must first be mounted. Some of these mounts include
DIN rail.
Relay Considerations
Before you buy an electromechanical relay, here are a few thoughts to keep in mind.
* Know the number of closed, open, and changeover contacts.
* What's the maximum current and voltage for a switch in AC and DC circuits?
* Find out the relay's operate and break times. The operating temperature is also important.
* Some features to look out for include:
voltage sensitive.
