NBRA-656C 可编程逻辑控制器由CPU、指令及数据内存、输入/输出接口、电源、数字模拟转换等功能单元组成。其出现之初的目的是替代机械开关装置（继电模块），后来随着不断地发展，这些当初功能简单的计算机模块已经有了包括逻辑控制、时序控制、模拟控制、多机通信等各类功能。

NBRA-656C PLC和变频器在工业自动化领域中都有广泛的应用，但它们的用途存在明显的区别。

NBRA-656C PLC（可编程逻辑控制器）是一种专门为在工业环境下应用而设计的数字运算操作电子系统。它的主要功能是通过可编程的存储器执行逻辑运算、顺序控制、定时、计数和算术运算等操作，并通过数字式或模拟式的输入输出来控制各种类型的机械设备或生产过程。简而言之，PLC主要用于控制和监视工业生产过程中的各种设备和系统。

变频器则是应用变频技术与微电子技术，通过改变电机工作电源频率方式来控制交流电动机的电力控制设备。变频器主要用于调节电机的速度和性能，从而实现生产过程的自动化和节能。它可以控制电机的启动、停止、速度和转向，并且具有过流、过压、过载保护等多种保护功能。

因此，NBRA-656C PLC和变频器在工业自动化领域中的应用目的有所不同。PLC主要用于工业生产过程的控制和监视，而变频器则主要用于电机速度的调节和控制。在实际应用中，PLC和变频器可以配合使用，以实现更复杂、高效的自动化生产过程。

The BRA-656C Programmable Logic Controller (PLC) is a digital operational electronic system designed specifically for use in industrial environments. It uses a programmable memory in which the instructions for performing operations such as logical operations, sequence control, timing, counting and arithmetic operations are stored, and various types of mechanical equipment or production processes are controlled through digital or analog inputs and outputs.

The NBRA-656C programmable logic controller is composed of CPU, instruction and data memory, input/output interface, power supply, digital analog conversion and other functional units. At the beginning of its appearance, the purpose is to replace the mechanical switching device (relay module), and later with continuous development, these computer modules with simple functions have included logic control, timing control, analog control, multi-machine communication and other functions.

Both the NBRA-656C PLC and inverter have a wide range of applications in the field of industrial automation, but there are obvious differences in their uses.

The BRA-656C PLC (Programmable Logic Controller) is a digital arithmetic operation electronic system specifically designed for use in industrial environments. Its main function is to perform operations such as logic operations, sequence control, timing, counting and arithmetic operations through programmable memory, and to control various types of mechanical equipment or production processes through digital or analog input and output. In short, PLC is mainly used to control and monitor various equipment and systems in the industrial production process.

Inverter is the application of frequency conversion technology and microelectronics technology, by changing the motor working power supply frequency to control the AC motor power control equipment. The frequency converter is mainly used to adjust the speed and performance of the motor, so as to realize the automation and energy saving of the production process. It can control the start, stop, speed and steering of the motor, and has a variety of protection functions such as overcurrent, overvoltage and overload protection.

Therefore, the purpose of application of NBRA-656C PLC and inverter in the field of industrial automation is different. PLC is mainly used for the control and monitoring of industrial production processes, while the inverter is mainly used for motor speed regulation and control. In practical applications, PLCS and inverters can be used together to achieve more complex and efficient automated production processes.
