Time relay principle:Air-damped time relays are often used in AC circuits, which use the principle of air throttling through small holes to obtain delayed action. It consists of three parts: the electromagnetic system, the delay mechanism and the contacts.Wiring method for time relay:1. Control wir... read more
Dedicated solid state relays can have short-circuit protection, overload protection and over-temperature protection functions, and combined with logic-cured package to realize the intelligent modules required by users, directly used in the control system. Solid state relays have been widely used in... read more
Because solid state relays have no mechanical contacts and other mechanical parts, their reliability is very high. The solid-state relay does not generate electric sparks and has no noise at the moment of on and off. Its switching speed is quite fast and the operating frequency is also quite high. ... read more
Solid-state relay (SOLIDSTATERELAYS, hereinafter abbreviated as "SSR") is a new type of non-contact switching device composed of solid-state electronic components. It uses the switching characteristics of electronic components (such as semiconductors such as switching triodes and triacs). , Can ach... read more
Power regulator thyristor is an abbreviation of thyristor rectifier. It is a high-power semiconductor device with a four-layer structure with three PN junctions, also known as a thyristor. It is one of the more commonly used semiconductor devices due to its small size, relatively simple structure, ... read more
A universal relay is a relay that can be used universally in a certain field or in many fields. A relay is an electrical appliance that causes a predetermined step change in a controlled quantity in an electrical output circuit when a change in an input quantity (excitation quantity) reaches a pres... read more
The comparison between traditional relays and solid-state relays involves many types, so the following comparison between electromagnetic relays and corresponding solid-state relays illustrates their differences: 1. Structural difference: The electromagnetic relay works by using the suction force g... read more
In the process of using the solid-state relay, it is still good to check all aspects. After a period of heating, when I check it again, I find that the solid-state relay is broken. What is the reason for this? It is mainly the effect of temperature. What are the effects of temperature on the use of... read more
Classification according to the overall dimensions of the relay: 1. Miniature relay: a relay with the longest side size not greater than 10 mm. 2. Subminiature miniature relays: Relays with the longest side larger than 10 mm but not larger than 25 mm. 3. Miniature miniature relay: The relay with th... read more
