10秒延时继电器K2#58833310
继电器是具有隔离功能的自动开关元件，当输入回路中激励量的变化达到规定值时，能使输出回路中的被控电量发生预定阶跃变化的自动电路控制器件。
继电器具有能反应外界某种激励量(电或非电)的感应机构、对被控电路实现"通"、"断"控制的执行机构，以及能对激励量的大小完成比较、判断和转换功能的中间比较机构。
继电器广泛应用于遥控、遥测、通讯、自动控制、机电一体化及和航天技术等领域，起控制、保护、调节和传递信息的作用。

Relay is an automatic switching element with isolation function. When the change of excitation quantity in the input circuit reaches the specified value, it can make the controlled electric quantity in the output circuit change in a predetermined step.
The relay has an induction mechanism that can respond to some external excitation quantity (electric or non-electric), an actuator that can control the controlled circuit "on" and "off", and an intermediate comparison mechanism that can complete the comparison, judgment and conversion functions of the excitation quantity.
Relays are widely used in remote control, telemetry, communication, automatic control, electromechanical integration and aerospace technology and other fields to control, protect, regulate and transmit information.
