216GD61a HESG324436R3-A HESG324428 ABB 电控制器件

216GD61a HESG324436R3-A HESG324428是一种电控制器件，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）之间的互动关系。通常应用于自动化的控制电路中，它实际上是用小电流去控制大电流运作的一种“自动开关”。故在电路中起着自动调节、安全保护、转换电路等作用。

216GD61a HESG324436R3-A HESG324428一般由铁芯、线圈、衔铁、触点簧片等组成的。只要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。这样吸合、释放，从而达到了在电路中的导通、切断的目的。

对于继电器的“常开、常闭”触点，可以这样来区分：继电器线圈未通电时处于断开状态的静触点，称为“常开触点”；处于接通状态的静触点称为“常闭触点”。

继电器按动作原理可分为电磁式、感应式和电动式等；按触点数可分为单触点、双触点和多触点等；按连接方式可分为固定连接式和可插拔式等；按防护特征可分为密封式、封闭式和非密封式等。此外，继电器还可以根据用途、使用场合等进一步分类。

继电器是一种电子控制器件，216GD61a HESG324436R3-A HESG324428具有控制系统（输入回路）和被控制系统（输出回路），通常应用于自动化的控制电路中。

216GD61a HESG324436R3-A HESG324428 is an electrical control device that has an interaction between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automated control circuits, it is actually an “automatic switch” that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit.

216GD61a HESG324436R3-A HESG324428 is generally composed of iron core, coil, armature, contact reed, etc. As long as 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 under the action of electromagnetic force attraction to attract the iron core, thereby 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). This suction, release, so as to achieve the purpose of conduction in the circuit, cut off.

For the “normally open, normally closed” contact of the relay, it can be distinguished in this way: the static contact in the disconnected state when the relay coil is not powered on is called “normally open contact”; The static contact in the connected state is called “normally closed contact”.

Relays can be divided into electromagnetic type, induction type and electric type according to the principle of action; According to the number of contacts can be divided into single contact, double contact and multi-contact, etc. According to the connection mode can be divided into fixed connection type and pluggable type; According to the protection characteristics can be divided into sealed, closed and non-sealed. In addition, relays can also be further classified according to the purpose, use of the occasion, etc.

A relay is an electronic control device, 216GD61a HESG324436R3-A HESG324428 has a control system (input loop) and a controlled system (output loop), usually used in the control circuit of automation.
