What Is The Main Difference Between A Relay And An Ordinary Switch?

图片
What is the main difference between a relay and an ordinary switch? Today  Power Relay Wholesaler  will give you a detailed explanation. The relay needs an electrical signal to control the switching of the relay. Ordinary switches require manual control of the switch. A relay is an electrical control component that is an electrical appliance that causes a predetermined step change in the electrical output circuit when the input quantity changes to a specified requirement. It has an interaction between the control system and the controlled system.  High sensitivity Relays  are commonly used in automated control circuits, which are actually an "automatic switch" that uses small currents to control large current operation. Therefore, it plays the role of automatic adjustment, safety protection and conversion circuit in the circuit. A switch is an electronic component that can open a circuit, interrupt current, or cause it to flow to other circuits. The most common switch

Can Automotive Relay Be Used For A Long Time?

图片
For the  Automotive Relay  to be able to power up for a long time, different people have different answers, which test the understanding of the car relay. Some people say that they can't be powered for a long time. Long-term power-on will burn out the car relay. Some people say that they can be powered for a long time. The home circuit is our common circuit. If the home circuit is kept energized for a long time, we know that it is a waste of electricity, and secondly it has an impact on the service life of the appliance, which will promote the aging of the circuit. Automotive relays can not be used for long periods of time. This problem is explained in the structure of automotive relays. The contacts of the car relay are divided into two states: normally closed and normally open. What do you think of here? The following  Automotive Relay Supplier  analyzes in detail whether the automotive relay can be used for a long time. As an example, the start-up relay can not be powered for

What Are The Technical Parameters Of The Main Products Of The Relay?

A relay is an automatic control device that changes the output when the input quantity (electricity, magnetism, sound, light, heat) reaches a certain value. So what are the technical parameters of the main products of the relay? Today,  High sensitivity Latching Relays Wholesaler  will give you an explanation. 1. Rated working voltage The rated working voltage is the voltage required by the coil when the relay is working normally. Depending on the type of relay, it can be either an AC voltage or a DC voltage. 2. DC resistance The DC resistance is the DC resistance of the coil in the relay and can be measured by a universal meter. 3. Pull-in current The pull-in current is the minimum current at which the relay can generate a pull-in action. In normal use, the given current must be slightly larger than the pull-in current so that the relay can operate stably. For the working voltage applied to the coil, generally do not exceed 1.5 times the rated working voltage, otherwise a

Three Ways To Use Relays Correctly

What is the correct way to use the relay? Today  High sensitivity Latching Relays Wholesaler  will come to you to find the answer. 1. The choice of relay rated working voltage The rated operating voltage of the relay is one of the most important technical parameters of the relay. When using a  48v Relay , you should first consider the operating voltage of the circuit in which it is located (ie, the circuit in which the relay coil is located). The rated operating voltage of the relay should be equal to the operating voltage of the circuit in which it is located. The operating voltage of the circuit is generally 0.86 of the rated operating voltage of the relay. Note that the workpiece voltage of the circuit should not exceed the rated working voltage of the relay, otherwise the relay coil is easy to burn. In addition, some integrated circuits, such as the NE555 circuit, can directly drive the relay. Some integrated circuits, such as COMS circuits, have a small output current. A tran

The relay is an automatic switching component with isolation function. It can be divided into: power relay, telecom relay,  Rutomotive Relay , latching relay, etc. It is widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronic equipment. One of the important control elements. According to international market research, driven by increased demand for distribution automation investment, by 2021, the global automatic relay market will reach US$1.033 billion, with a compound annual growth rate of 3.9%. The  Relay Electronics Wholesaler  believes that the increase in energy demand will promote the market's demand for power supply quality, thus promoting the steady growth of demand for automatic relays. From a regional perspective, North America will be the world's largest market for automatic relay demand, followed by Asia Pacific and Europe. From a single country perspective, due to intensive power infrastructure upgrades an

What Are The Four Test Methods For Power Relays?

Power Relay 's four test methods, there are many kinds of power relay test methods in common relays, relays are often used in various industries, such as: automotive, electrical, electronic products, etc. The role of the relay is to protect the circuit , limit the current, can achieve the closing effect, the following  Power Relay Wholesaler  to explain the test method. 1. Measuring contact resistance Use the resistance file of the universal meter to measure the normally closed contact and the dynamic point resistance, the resistance value should be 0, (the contact resistance value can be measured within 100 milliohms in a more precise way); and the normally open contact and movement The resistance of the point is infinite. This makes it possible to distinguish between a normally closed contact and a normally open contact. 2. Measuring coil resistance The resistance of the power relay coil can be measured by the universal meter R×10 Ω file to determine whether the coil has

How Should The Relay Be Wired?

Because the main purpose of  Power Relay  is to control the strong electricity with weak current. (including low voltage control high voltage, small current control high current). The effect is achieved by controlling the on and off of its own coil to turn its contacts on and off. (Popular point is to control the magnet to suck or not, and the magnet to control the contact switch) Therefore, the connector of the relay includes the contact connector of its control circuit and the connector that controls its coil. If you still have any questions, please read the instructions carefully, or the relay itself, we are  Power Relay Supplier , can help you solve all doubts.

The Correct Use Of The Relay

As a  Power Relay Supplier , let me talk about the proper use of relays today. 1, the choice of relay rated working voltage The rated operating voltage of the relay is one of the most important technical parameters of the relay. When using a relay, you should first consider the operating voltage of the circuit in which it is located (ie, the circuit in which the relay coil is located). The rated operating voltage of the relay should be equal to the operating voltage of the circuit in which it is located. The operating voltage of the circuit is generally 0.86 of the rated operating voltage of the relay. Note that the workpiece voltage of the circuit should not exceed the rated working voltage of the relay, otherwise the relay coil is easy to burn. In addition, some integrated circuits, such as the NE555 circuit, can directly drive the relay. Some integrated circuits, such as COMS circuits, have a small output current. A transistor amplifier circuit is required to drive the relay. T

What Should I Do If The Relay Is Under Voltage?

Once the voltage applied to the coil is insufficient, the  Power Relay  will not work or the operation will be unstable, which will cause the durability of the contact to decrease or the contact point such as welding to be blocked. In particular, in a large motor or the like, when the power is turned on, the voltage applied to the relay coil sometimes drops at the moment of a load operation in which a large inrush current is generated. If the relay is operated in a low voltage state, even if it is a vibration or shock value within the specifications specified in the specifications and catalogues, the relay may malfunction. Therefore, apply a rated voltage to the coil of the relay. For fluctuations in the power supply voltage, apply a voltage to the coil that each relay can fully operate. If a voltage is applied to the coil that does not allow the relay to fully operate, the coil will be abnormally heated, causing the coil to burn out. In addition, if a motor, a solenoid, a trans
