对二极管的介绍：二极管电子元件是一种带有两个电极的器件，只允许电流沿单一方向流动，其中许多使用其整流功能，而变容二极管则用作电子可调电容器。大多数二极管的当前方向性通常被称为整流功能。一个最常见的功能
A Basic Introduction to Relay
The relay is an automatic switching element with isolation function. It is widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronics. It is one of the most important control components. Relays generally have sensing mechanisms (input parts) that reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.) and the actuator (output portion) controls "off" and "on". Between the input portion and the output portion of the relay, there is also an intermediate mechanism (drive portion) that couples the input amount, functions, and drives the output portion. As a control element, in summary, the relay has the following effects: 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 diffe
