1. Know About Different Types of Relays and
Their Application
Most complex electronic machinery cannot be operated effectively without relays. Relays are
electromagnetic switches responsible for closing and opening circuit contacts within an
electronic circuit. Relays are of various types and are used for industrial and household
purposes. For industrial purposes, it is always advisable to buy relays and other electronic
components from trusted and reliable manufacturers. When it comes to relays, Omron is the
world leader, known for its best quality and highly versatile range of relays. Express Technology
Group is the trusted Omron relays wholesale distributors from where you can order all types
of Omron relays at an unbeatable price. These relays are used in automobiles, washing
machines, medical equipment, tanks, aircraft, and ships have relays in them.
What are the different types of relays?
Depending upon the type of machinery and application, relays are of various types. Read on to
find out about the different types of relays.
 Electromagnetic Relay – Electromagnetic relay is the most frequently used relay in
various pieces of machinery. It transforms mechanical energy into electrical singles. Its
main parts are coils, magnetic cores, springs, contacts, and armatures.
 Latching Relay – A Latching relay has only one current pulse and the relay remains the
same till the time the pulse stops affecting it. It also keeps control over the power
consumption in a circuit.
 Thermal Relay – These types of relays stand second on the list of frequently used relays.
Thermal relays of two types are available for household and industrial purposes in
offline and online stores like Express Technology Group. One of them provides
excitation in the form of heat and the other one does that in the form of current.
 Reed Relay – Reed relays have a magnetic material made of a thin steel plate called the
contact, magnetic system, and spring all at once. One end of the board is fixed and
another one is backed by conductive elements, it moves by getting affected due to the
external magnetic field.
 High Voltage Relay – Most modern electronic pieces of machinery require insulation
test systems and this is the primary reason behind the demand for high voltage relays.
High voltage relays are of two types – one which is for all load current components and
others which are low-voltage and high-voltage, between the contact and control coil.

2.  Time Relay – Popularly called ‘Delay Relays’, they increase the stability of automatic
control systems. It is used for improving the functions of a system in the field of
electronics and engineering.
 Voltage Relays – These are made especially for controlling current levels to a pre-
determined value. These relays measure the level of execution in the system and are
called measuring relays.
 Power Factor Relay - This relay is used when the altering current increases or decreases
in comparison to the pre-determined level. Power factor relays are used as power factor
correction in electronic appliances.
 Solid State Relay – Designed especially for fast switching applications, a solid state relay
has a single epoxy resin molded solid state module.
 Flash Relay – Also called the Flasher, this relay is used in lamps with one signal and in
parts of signal boards that have many valves in them.
 Rotary Relay – Rotary relay or motor-driven relay moves ahead of the armature and the
contacts of the relay get replaced by rotatory motion.
 Sequence Relay – Sequence relays are known by various names including alternators,
step relays, and triggers. These relays open and close contacts in a pre-determined
sequence by using a catch mechanism.
 Microprocessor Relay – Microprocessor relays are attached to small computers. These
computers have similar features with the external current and the voltage transformers.
 Polarized Relays – Polarized relays are the direct current electromagnetic relay with an
additional constant magnetic field source. The armature of the relay is affected by this
source.
 Frequency Relay – When the frequency in an electrical system is increased then severe
damage can be caused due to excess power. To avoid this, frequency relays are used.
Their main aim is to prevent the power system from collapsing or getting permanently
damaged.
Conclusion
Relays are one of the vital electronic components which are used in many appliances. They
have various types whose applications are for both, household purposes and industrial
purposes. For industrial purposes, buy relays from trusted electronic component
manufacturers. Omron can be an ideal choice for buying relays. The Express Technology Group
which are Omron relays wholesale suppliers can provide the best quality relays at an
affordable price.
