A general-purpose relay is a relay that can be used in a certain field or in many fields. The relay is an electric appliance in which the predetermined amount of change occurs in the electric output circuit when the change in the input amount ...

A power relay is a device that can make a transition in one or more electrical output circuits when the input (or excitation) meets certain specified conditions.The action process of the contact can be divided into two parts: contact closure ...

The floating controller uses the buoyancy of the float and its own weight. The vertical push pin perpendicular to the liquid surface and the upper and lower positioning pins on the guide rod directly push and pull the FK1 type ...

The action process of the contact can be divided into two parts: contact closure and contact disconnection, that is, the process of the pull-in and release of the relay, which are cyclically switched at a certain frequency to form a contact opening ...

Time relays are a very important component in electrical control systems. In many control systems, time relays are required to implement delay control. A time relay is an automatic control device that uses electromagnetic principles or mechanical ...

In actual work, we divide the solid state relay into two types according to the load, one is the inductive load, and the other is the resistive load. The most common inductive load is the motor.Common heating elements, thermocouple incandescent lamps ...

The magnetic holding relay is also a kind of relay, but it has more stable performance than other relays, and has a smaller volume and a stronger carrying capacity. The magnetic holding relay is essentially an automatic switch that can ...

1. In order to prevent contamination of the surface of the lead end, it should not be directly contacted with the lead end. Otherwise, the solderability may be degraded. 2. The position of the lead end should be consistent with the hole position ...

The basic characteristics of circuit board relays are; 1. Strong point switching ability; 2. Has a set of normally open and a set of conversio; 3. High withstand voltage between contact and coil; 4. With AC voltage input; 5. Can be equipped with LED ...
