First of all, let's take a look at the electromagnetic relay. It is a kind of operation hub that undertakes electrical control cabinets and balers. The work of electromagnetic relays is generally composed of iron cores, coils, armatures, contact reeds, etc.It has a control system (also known as an input loop) and a controlled system (also known as an output loop). It is usually used in automatic control circuits. It is an automatic switching and weak current control circuit to control high voltage and strong current working circuits, and can realize remote control and production automation, and its classification methods are not the same.Therefore, the automatic baler will also appear in its figure, which brings a lot of outstanding advantages to these new functional balers.
