什么是交流接触器 交流接触器具有失压保护功能,有一定过载能力,因此,也具有过载保护功能。 交流接触器运行中噪音过大可能是由于短路环脱落或开裂引起的。交流接触器铁心上的短路环断裂后会使动静铁心不能释放。以上是3条关于交流接触器的描述,看上去都十分靠谱,可实际上只有第二句是正确的,要完全明白其中的错误,首先...
The main function of the communication interface is to realize data exchange (communication) between PLC and external equipment. The communication interface has various forms, the most basic are standard serial interfaces such as UBS, RS-232, RS-422/RS-485. It can be connected by multi-core ca...
Now, let’s talk a bit about the wire terminals on the contactors. 1) Coil terminals On the front of the contactor, you’ll see two wire terminals of A1 and A2. This is where we can connect a 24-volt DC power to the coil to energize it. ...
