What is the difference between a relay and a contactor? Let's let  Relay Electronics Wholesaler  tell you the answer today. The coil of the relay is connected to the corresponding circuit according to different DC, AC, current and voltage. When the condition of the coil is met, the armature is attracted. The normally open normally closed contact is actuated accordingly, which plays a different role in the loop. Function, some relays can be charged for a long time, and some can not, so some relays in the circuit will not cause the outage of electrical equipment even if the power is lost, and some relays will not cause the equipment to start running even if it is in the electricity industry. The coil of the contactor is connected to the control loop of the low-voltage device. When the voltage across the coil reaches 70% of the rated value, the core is magnetically saturated to attract the armature, and at the same time, its main contact is connected to the main power supply to t

The main difference between relay and ordinary switch : The relay requires 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. 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 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 is an electromechanical device that operates, with one or several electronic contacts. The "closed" of th

Jan. 05, 2019 Power Relay  connection method: When driving a relay with a transistor, it is recommended to connect the collector. In addition, when the relay is ON, the rated voltage is applied, and when the relay is OFF, the voltage is zero. This is a method to avoid malfunction. Collector connection The most common connection method, the action is stable. 2. Emitter connection Sometimes the consideration of the action is not to be used on the relay, no voltage is applied at all, and the transistor is not conductive at all. 3. Parallel connection The overall power consumption of the circuit is increased, and the relay voltage needs to be considered. Our  Electromagnetic Power Relay  can be customized according to your requirements.

A considerable part of the components of the relay are riveted and fitted, and the main problem is that the riveting is loose or the bonding strength is poor. This kind of fault will make the relay parameters unstable, the parameters change greatly under high and low temperature, and the mechanical vibration and impact resistance are poor. The main cause of this problem is the poor condition of the riveting parts, the improper placement of the parts, the unqualified quality of the work tools or the inaccurate installation. Therefore,  48v Relay Supplier  reminds you to carefully check whether the tool and the riveted parts meet the requirements before the welding. The contact is the electrical contact part of the relay to complete the switching load. The contacts of some products are press-fitted by riveting. The main disadvantages are loose contact, cracked contact or excessive positional deviation. This will affect the contact reliability of the relay. The loosening of the erasing

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,  Relay Electronics Manufacturer  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

In the past ten years, China's information industry has developed rapidly at a rate three times that of other industries. The communications and automotive industries are also moving forward at a rapid pace. At the same time, the home appliance industry has begun to emerge as an important demand driver. With the overall improvement in the quality of life of Chinese products, more and more consumers are interested in new or upgraded appliances, which in turn stimulates the demand of  Power Relay . According to the forward-looking report of China's current relay industry market foresight and investment planning analysis released by Prospective Industry Research Institute, the use of relays in these industries is considerable. With the development of these industries, it will undoubtedly promote the further expansion of the relay market. In 2010, although the number of relay outlets decreased, the value of exports increased, indicating that the added value of the export relays
