140CRS12420 I/O模塊，即輸入/輸出模塊，是工業(yè)自動化系統(tǒng)中的重要組成部分。以下是關(guān)于I/O模塊的詳細介紹：
定義與分類：
I/O模塊指的是PLC(可編程邏輯控制器)的輸入/輸出模塊，用于實現(xiàn)PLC與工業(yè)生產(chǎn)過程的聯(lián)系。
根據(jù)功能和用途，I/O模塊可分為離散、模擬和特殊模塊等多種類型。
在更廣泛的編程和應(yīng)用領(lǐng)域，I/O模塊還包括文件I/O、字節(jié)流I/O、緩沖I/O、文本I/O、套接字I/O、序列化I/O和內(nèi)存映射I/O等，用于滿足不同的編程需求。
作用：
輸入模塊：用于接收和采集來自各種傳感器、開關(guān)和變送器等設(shè)備的輸入信號，如開關(guān)量輸入信號和模擬量輸入信號。輸入模塊還需將這些不同的電平信號轉(zhuǎn)換成數(shù)字信號，以便CPU能夠接收和處理。
輸出模塊：140CRS12420 接收中央處理器處理過的數(shù)字信號，并將其轉(zhuǎn)換成現(xiàn)場執(zhí)行部件能接收的信號，如接觸器、電磁閥、調(diào)節(jié)閥、調(diào)速裝置等的控制信號，以及指示燈、數(shù)字顯示器和報警裝置等的顯示或報警信號。
特點與應(yīng)用：
產(chǎn)品種類豐富：140CRS12420 包括數(shù)字量輸入/輸出模塊、模擬量輸入/輸出模塊、溫度采集模塊以及高速計數(shù)器模塊等，滿足各種工業(yè)需求。

The 140CRS12420 I/O module, the input/output module, is an important part of the industrial automation system. Here is a detailed description of the I/O module:
Definition and classification:
The I/O module refers to the input/output module of the PLC (programmable logic controller), which is used to realize the connection between the PLC and the industrial production process.
Depending on their function and purpose, I/O modules can be divided into discrete, analog and special modules.
In the broader field of programming and application, I/O modules also include file I/O, byte stream I/O, buffered I/O, text I/O, socket I/O, serialized I/O, and memory-mapped I/O to meet different programming needs.
Functions:
Input module: Used to receive and collect input signals from various sensors, switches and transmitters, such as switching input signals and analog input signals. The input module also needs to convert these different level signals into digital signals so that the CPU can receive and process them.
Output module: 140CRS12420 receives the digital signal processed by the central processor and converts it into the signal that can be received by the field executive parts, such as the control signal of the contactor, solenoid valve, regulating valve, speed regulating device, etc., as well as the display or alarm signal of the indicator light, digital display and alarm device.
Features and applications:
Wide range of products: 140CRS12420 includes digital input/output module, analog input/output module, temperature acquisition module and high-speed counter module to meet various industrial needs.
