Relays are commonly used in automatic control systems to turn the circuit on and off to issue control commands and reflect device status to form automatic control and remote control circuits. Automatic control in all areas uses relays. As an  Automotive Relay Manufacturer , let's share with you what it does. 1) Expand the scope of control. For example, when the multi-contact relay control signal reaches a certain value, the multi-circuit circuit can be switched, disconnected, and turned on at the same time according to different forms of the contact group. 2) Zoom in. For example, sensitive relays, intermediate relays, etc., can control very high power circuits with a very small amount of control. 3) Integrated signal. For example, when a plurality of control signals are input to a multi-winding relay in a prescribed form, the comparison is integrated to achieve a predetermined control effect. 4) Automatic, remote control, monitoring. For example, a relay on an automated

As an  Automotive Relay Manufacturer , we continue to share with you how to use small power relays. 2. DC resistance: This refers to the DC resistance of the coil. In some product specifications, the rated operating voltage and DC resistance are given. In this case, the rated operating current can be obtained according to Ohm's law. If the rated operating current and DC resistance are known, the rated operating voltage can also be determined. 3. Pull-in current: It refers to the minimum current that a small high-power relay can generate a pull-in action. In actual use, in order to make the small high-power relays reliably pull in, the given voltage can be equal to or slightly higher than the rated working voltage. Generally do not exceed 1.5 times the rated working voltage. Otherwise the coil will be burnt. 4. Release current: It refers to the maximum current that the small high-power relay generates to release. If the current of the small high-power relay in the pull-in s

Power Relay is a device that can make a jump in one or more electrical output circuits when the input (or excitation) meets certain specified conditions. It can also be used in a neutral point direct grounding system. Directional component for zero sequence current protection. As an  Automotive Relay Manufacturer , let's talk about the application and working principle of the small Power Relay today. Power Relay is often used in applications such as air conditioners in home appliances. In recent years, high-powered household appliances have developed rapidly, such as electric water heaters, water dispensers, etc., which use  Power Relay . 1. Rated operating voltage or rated operating current: This refers to the voltage or current required by the coil when operating at high power. The construction of one model is generally the same. In order to adapt to different voltage circuit applications, one type of model usually has a variety of rated operating voltages or rated operati

As an  Automotive Relay Manufacturer , we have the following recommendations for the selection of solid state relays. 1. The steady state current at the output of the solid state relay must not exceed the rated output current. Almost all loads have surge currents, such as so-called purely resistive electric heating elements, but they have a positive temperature coefficient, and the resistance at low temperatures is small, so the instantaneous current is just large when starting up. 2. Solid state relays have input characteristics of 3 to 32V DC, which has a wide control range. The input current to the control loop of a single-phase DC/AC solid state relay is typically around 10 mA. The control loop input current of the three-phase solid state relay is generally around 30 mA. 3. The control operating frequency of the AC solid state relay should not exceed 10 Hz. The control signal period of the DC solid state relay should be greater than 5 times the sum of the on and off times

As an  Automotive Relay Manufacturer , we continue to explain the precautions when using small power relays. 3. Pull-in current: It refers to the minimum current that a small high-power relay can generate a pull-in action. In actual use, in order to make the small high-power relays reliably pull in, the given voltage can be equal to or slightly higher than the rated working voltage. Generally do not exceed 1.5 times the rated working voltage. Otherwise the coil will be burnt. 4. Release current: It refers to the maximum current that the small high-power relay generates to release. If the current of the small high-power relay in the pull-in state is reduced, when the current is reduced to a certain level, the small-sized high-power relay returns to the state of no power-on, which is called the release action of the small-sized high-power relay. The release current is much smaller than the pull-in current. 5. Load: It refers to the voltage or current allowed by the contact of a sm

Relays are commonly used in automatic control systems to turn circuits on and off to form automatic control and remote control circuits. Whether it is a core component of a relay signal system, or an interface component of an electronic or computerized signal system, it plays an important role. The same is true for power relays. As a  12V Relay Wholesaler , today we will analyze the things to be aware of when using small high-power relays. 1. Rated operating voltage or rated operating current: This refers to the voltage or current required by the coil when operating at high power. The construction of one model is generally the same. In order to adapt to different voltage circuit applications, one type of model usually has a variety of rated operating voltages or rated operating currents, and is distinguished by specifications. 2. DC resistance: This refers to the DC resistance of the coil. In some product specifications, the rated operating voltage and DC resistance are given. In

As an  Automotive Relay Manufacturer , let's talk about the factors that need to be considered when choosing a photoelectric sensor. 1. The size of the photoelectric sensor should conform to its own production environment, and it needs to be measured before making a selection. 2. Select the sensing mode suitable for the environment and select it appropriately. 3. The choice of sensing range should be based on the production environment of the product, regardless of whether the range is large or small, and should be combined with its own characteristics. 4. In the above installation method, if there is a technician, you can give it to the technicians to install it. If there is no technician, you should learn from the advanced experience of others. 5. As for other aspects of the working mode, the choice of working voltage, as well as the light source, connection method, packaging materials, etc., according to the description of the photoelectric sensor is to carry out sele
