继电器是一种电子控制器件，它具有控制系统（又称输入回路）和被控制系统（又称输出回路），通常应用于自动控制电路中，它实际上是用较小的电流去控制较大电流的一种“自动开关”。在电路中起着自动调节、安全保护、转换电路等作用。

CR215GH87继电器有很多类型，不同类型的继电器有不同的工作原理和特性，例如：

电磁继电器：CR215GH87一般由铁芯、线圈、衔铁、触点簧片等组成。在线圈两端加上一定的电压，线圈中就会流过一定的电流，从而产生电磁效应，衔铁就会在电磁力吸引的作用下克服返回弹簧的拉力吸向铁芯，从而带动衔铁的动触点与静触点（常开触点）吸合。当线圈断电后，电磁的吸力也随之消失，衔铁就会在弹簧的反作用力返回原来的位置，使动触点与原来的静触点（常闭触点）吸合。

温度继电器：CR215GH87当外界温度达到给定值时而动作的继电器。

高频继电器：用于切换高频、射频线路而具有最小损耗的继电器。

极化继电器：CR215GH87有极化磁场与控制电流通过控制线圈所产生的磁场综合作用而动作的继电器。

此外，CR215GH87还有很多其他类型的继电器，如时间继电器、固态继电器等等。不同类型的继电器适用于不同的应用场景和需求。

Relay is an electronic control device, it has a control system (also known as the input loop) and the controlled system (also known as the output loop), usually used in automatic control circuit, it is actually a small current to control the larger current of an "automatic switch". In the circuit plays the role of automatic regulation, safety protection, conversion circuit, etc.

There are many types of CR215GH87 relays, different types of relays have different working principles and characteristics, such as:

Electromagnetic relay: CR215GH87 is generally composed of iron core, coil, armature, contact reed and so on. When a certain voltage is added to both ends of the coil, a certain current will flow through the coil, resulting in an electromagnetic effect, and the armature will overcome the pull of the return spring to attract the core under the action of the electromagnetic force, thus driving the moving contact of the armature and the static contact (normally open contact). When the coil is powered off, the electromagnetic suction will also disappear, and the armature will return to the original position in the spring reaction force, so that the moving contact and the original static contact (normally closed contact).

Temperature relay: CR215GH87 relay that operates when the external temperature reaches a given value.

High-frequency relay: A relay for switching high-frequency and RF lines with minimal loss.

Polarized relay: The CR215GH87 has a polarized magnetic field and the control current through the control coil generated by the combined action of the magnetic field to operate the relay.

In addition, CR215GH87 has many other types of relays, such as time relays, solid state relays, and so on. Different types of relays are suitable for different application scenarios and requirements.
