ABB 电源模块 PFSA146 3BSE008844R1 PLC控制器系统

采用简明的梯形图、逻辑图或语句表等编程语言，而无需计算机知识，因此系统开发周期短，现场调试容易。另外，可在线修改程序，改变控制方案而不拆动硬件。

一台小型PLC内有成百上千个可供用户使用的编程元件，有很强的功能，可以实现非常复杂的控制功能。它与相同功能的继电器系统相比，具有很高的性能价格比。PLC可以通过通信联网，实现分散控制，集中管理。

由于PLC的输出元件被封装在印制电路板上，PFSA146 3BSE008844R1并且连接至端子板，若将连接输出元件的负载短路，将烧毁印制电路板

Using concise ladder diagram, logic diagram or statement table programming language, without computer knowledge, so the system development cycle is short, the field debugging is easy. In addition, the program can be modified online to change the control scheme without dismantling the hardware.

A small PLC has hundreds of programming components available to users, has a strong function, can achieve very complex control functions. Compared with the relay system with the same function, it has a high performance-price ratio. PLC can realize decentralized control and centralized management through communication networking.

Since the PLC output component is packaged on the printed circuit board, PFSA146 3BSE008844R1 and connected to the terminal board, if the load connected to the output component is short-circuited, the printed circuit board will be burned
