What are the methods of handling when the relay fails? The  Light Weight Relay Exporter  below explains to you: 1. For relays with hard terminals, no bending is allowed during installation to prevent air leakage due to rupture of the glass insulator. If it is installed in the form of a socket, it is necessary to select the socket in strict accordance with the specified insertion force to prevent over-tightening or looseness, and to ensure that the socket is clean and prevent contact failure. 2. If the relay is directly soldered on the printed board, the hole pitch of the printed board is required to meet the size requirements of the relay lead-out line, and the aperture should not be too small. It is necessary to ensure that the lead-out line can be smoothly inserted and left with the printed board. Appropriate clearance to prevent over-tightening of the roots. 3. For the relay of the soft terminal, if the lead is required to be bent and installed, it is necessary to clamp the r

What are the maintenance methods for relays? Let's take a look at the  Power Relay Supplier  below: 1, core troubleshooting The iron core failure mainly has the armature that cannot be sucked up after being energized. This may be caused by a broken wire, a foreign object between the static iron cores, and a low power supply voltage. Repair should be done differently. After power-on, if the armature is noisy. This may be due to uneven contact surfaces of the moving and static cores or oil contamination. When repairing, remove the coil, level or smooth the contact surface; if there is oil, it should be cleaned. 2, coil troubleshooting Coil faults are usually damaged by coil insulation; short circuit or grounding is caused by mechanical damage; because the power supply voltage is too low, the contact between the moving and static iron cores is not tight, so that the current flowing through the coil is too large, and the coil heats up and burns. When repairing, rewind the coil

Different people have different answers to the long-term power-on of the Automotive Relay, which tests the understanding of the  Automotive Relay . Some people say that they can't be powered for a long time. Long-term power-on will burn out the Automotive Relay. Some people say that they can be powered on 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  Automotive Relay Manufacturer  below analyzes in detail whether the automotive relay can be used for long periods of time. As an example, the start relay can not be en

Relays play a central role in systems consisting of relay technologies, such as relay interlocking, relay semi-automatic occlusion, etc. These systems are still in large numbers and will be used for quite a long period of time. In the system consisting of electronic components and microcomputers, such as computer interlocking, multi-information automatic blocking, general locomotive signal, hump automation and other systems, as the interface components, the system host and signal, track circuit, transfer Machine and other execution components are combined. Next,  Power Relay China Factory  gives you a brief description of how the relays are wired. 1. Control wiring: Think of it as a DC relay. 3.7 is used to connect 12V control voltage; 2.7 is used to connect 24V control voltage. Among them, 7 is regarded as the negative pole of direct current, and is connected to the neutral line when in use. 2 connected to the 220V fire line. 2. Work control: Although the control voltage is conne

A relay is an automatic control device that changes the output when the input quantity (electricity, magnetism, sound, light, heat) reaches a certain value. The  Automotive Relay  is a relay used in automobiles. This type of relay has high load switching power and high impact and vibration resistance. So what are the installation methods of the Automotive Relay? Let's take a look at it with Xiaobian! 1. Installation direction of Automotive Relay: If the installation direction is consistent with the direction of the relay's impact resistance, the performance of the relay can be fully utilized. It is recommended to make the impact direction perpendicular to the direction of movement of the contacts and the armature, which can effectively improve the vibration and shock resistance of the normally closed contacts in the non-excited state. When installing, make the contact axis of the relay parallel to the ground, which can avoid contact spatter and char on the contact surface an

What are the relays normally open and normally closed? Let the  Power Relay Supplier  tell you the answer today. Normally open: When the coil is not energized, the two contacts are open. After power-on, the two contacts are closed. It is represented by the pinyin head "H" of the word. Normally closed: When the coil is not energized, the two contacts are closed, and the two contacts are disconnected after power-on. It is represented by the pinyin head "D" of the hyphenation. A relay is an electrical control device that is an electrical device that causes a predetermined step change in the controlled output quantity in the electrical output circuit when the input quantity changes to meet the specified requirements. It has an interaction between the control system and the controlled system. Often used in automated control circuits, it is actually an "automatic switch" that uses small currents to control large current operation. Therefore, it plays the
