What are the voltage relay?

voltage relays are electrical equipment in which the primary function is to switch current from one circuit to another. The use of relay voltage allows you to control a large amount of current with a small amount of current. The relay is activated remotely by means of an electrical signal. In some applications, the remote signal may be pneumatic. One of the most common and earliest uses is the switching change of telephone and telegraph industries. They are also widely used in an automated test device and are also found in most major appliances and electronics, including computers. When the lever and contact touch each other, the circuit is reportedly closed. When both components do not touch, the perimeter is considered open. When the relay is activated, the lever moves from its present to the second position, from open to close or vice versa. This action is used to transfer energy from one district to another district.

One of the basic uses of sessions of voltage is easy to control on/off. An example would be in a cooling system that operates a compressor. When the compressor lights up, an increase in electric current is required to turn it on. The voltage relay is used to redirect or relay current into the compressor circuit at a suitable time.

voltage relays are also used in logical applications. This feature is particularly prevailing in testing devices. The voltage relay provides the ability of movable current from one point to another in a defined logical sequence.

Two widely defined categories of voltage sessions are electromechanical and solid condition. There are a number of different styles and types of ACH. Electromechanical relays The voltage contains movable mechanical parts. The relay action is controlled by a current flowing through a wire coil that creates a magnetic field for relay control. The magnetic force is used to move the contact lever, which causeE that an open circuit open or closed circuit opens.

The tension relay in a solid state use light from the light of the light emitting diodes. The lack of moving parts makes them more resistant than electromechanical types. In addition, the relay of solid states usually have faster reaction times, which increases them more efficient.

Another attribute characterized by a relay of voltage is the amount of load or current that are able to manipulate. In most cases, the relay is classified as a low voltage relay or a high -cost relay. In general, high -voltage relays work at more than 5,000 volts. However, there are applications in which high -cost relays use in lower rating.
