FOXBORO P0922YU FPS400-24 电源模块 美国

FOXBOROFPS400-24 P0922YUPLC的硬件组成与微型计算机相似，其主机由CPU板、存储器、输入／输出（I／O）接口、电源等几大部分组成；可配备如编程器、图形显示器、通信接口等外部设备。

CPU也称处理器，是由一片或几片大规模集成电路芯片组成的，相当于人的大脑，是PLC的核心部分；FOXBOROFPS400-24 P0922YUCPU的作用是可通过接口及软件向系统的各个部分发出各种命令，同时对被测参数进行巡回检测、数据处理、控制运算、报警处理及逻辑判断等，实现对整个PLC的工作过程进行控制；目前大多数小型PLC都用8位或者16位单片机作CPU。

I／O接口是输入（IN）／输出（OUT）接口的简称，是PLC主机与被控对象进行信息交换的纽带；PLC通过I／O接口与外部设备进行数据交换，PLC的输入输出信号有开关量、模拟量、数字量三种类型，所有的输入输出信号均经过光电等隔离，大大增强了PLC的抗干扰能力。

The hardware composition of FOXBOROFPS400-24 P0922YUPLC is similar to that of a microcomputer, and its host is composed of CPU board, memory, input/output (I/O) interface, power supply, etc. It can be equipped with external equipment such as programmer, graphic display, communication interface, etc.

CPU, also known as the processor, is composed of one or several large-scale integrated circuit chips, equivalent to the human brain, is the core part of the PLC; The function of FOXBOROFPS400-24 P0922YUCPU is to issue various commands to various parts of the system through the interface and software, and carry out circuit detection, data processing, control operation, alarm processing and logic judgment of the measured parameters, so as to control the working process of the whole PLC; At present, most small PLC use 8-bit or 16-bit MCU as CPU.

I/O interface is the input (IN)/output (OUT) interface for short, is the PLC host and the controlled object information exchange link; PLC through the I/O interface and external equipment for data exchange, PLC input and output signals have switching quantity, analog quantity, digital quantity three types, all the input and output signals are photoelectric isolation, greatly enhance the anti-interference ability of PLC.
