A-B 1746-NO4VA  输出模块

A-B 1746-NO4VA  输出模块开关量输入模块就是外部控制信号或现场检测信号给PLC CPU的处理模块，外部信号一般是按钮、接近开关、行程开关等。输出模块是PLC根据输入模块采入的信号和内部逻辑编程进行逻辑处理，处理后的结果过，开关量输出便由输出模块输出高低电平信号，驱动外部中间继电器、接触器、指示灯、电磁阀等元件，进而使外部设备进行相应的动作

PLC输出模块的作用是对输出信号进行功率放大。PLC的信号是以电平表示的，要使它在被读出的过程中不发生畸变，就需要有一定的储备能量或者说要有一定的信号功率。输出模块的作用实际就是功率放大器。输出模块就是可以驱动外部负载。
A-B 1746-NO4VA  输出模块常见的PLC输出器件有，晶体管、可控硅、继电器。
PLC输入模块用来接收，生产过程的各个参数。（启动 停止 ）

A-B 1746-NO4VA output module The switch input module is the processing module for external control signals or field detection signals to the PLC CPU. The external signals are generally buttons, proximity switches, travel switches, etc. The output module is the logic processing of PLC according to the signal taken in by the input module and internal logic programming. When the processed result is over, the output module outputs high and low level signals to drive external intermediate relays, contactors, indicator lights, solenoid valves and other components, so as to make external devices perform corresponding actions.

The function of PLC output module is to amplify the output signal. The signal of PLC is expressed in level, so it needs to have a certain reserve energy or a certain signal power if it is not distorted in the process of being read out. The function of the output module is actually a power amplifier. The output module can drive the external load.

The common PLC output devices of A-B 1746-NO4VA output module are transistors, thyristors and relays.

The PLC input module is used to receive various parameters of the production process. (Start Stop)

The PLC output module is used to send out the information obtained after the operation of the programmable controller, and to complete all kinds of control in the industrial field through the execution mechanism outside the machine. (Output for execution results) 1. Good anti-interference ability.

2. It can meet the matching requirements of various signals in industrial field.
