Thus far we have seen a selection of Input devices that can be used to detect or “sense” a variety of physical variables and signals and are therefore called Sensors. But there are also a variety of electrical and electronic devices which are classed...
In small and unknown sights we are indeed taking care of ourselves and our electrical. We install the best of wires, do the earthling securely and even buy the electrical goods which have the best of power history. But as a matter of fact we sometime...
The impact on the domestic market is weakened due to the pace of import slows down. In November, the relay import revenue is USD35.46 million, down 39.58% YoY and the link relative ratio decreases by 8.74 percent The figures show that the internation...
There are lots to learn with regard to electronic relays and relays in general. Some of these relays have a design. Construction and operational characteristics which are adaptable for a wide variety of uses. They have very high life expectancy and m...
Electromagnetic relay is an electronic control device. It has a control system (also called input loop) and a controlled system (also called output loop). It is usually used in automatic control circuits. It actually uses a smaller current. Applicat...
The relay is a device that uses low-current voltage and weak current circuit to control high-voltage and strong current circuit. Electromagnetic relay is a switch that uses an electromagnet to control the working circuit. When the protected componen...
The basic structure and working principle of the electromagnetic relay are similar to the contactor, which is composed of iron core, armature, coil, return spring and contact. Because the electromagnetic relay is used in the auxiliary circuit, its on...
Relay selection 1. Selection of voltage and currentThe selection should be based on the supply voltage of the control circuit and the maximum current that can be output, and then be selected according to whether the voltage and current of the control...
