140CPU31110 I/O模块导轨的背面安装带有连接器的印制电路板

I/O模块可以分为离散、模拟和特殊模块等多种类型，140CPU31110
模块都可以安装在带有多个插槽的导轨或者机架上，每个模块插人其中一个插槽。导轨或者机架具有不同规格，插槽数分为4、8、12等。一般情况下，电源模块插在第一插槽内，编号为0，PLC插在第二插槽内，各种类型的输入输出模块插在其余插槽内。I/O模块导轨的背面安装带有连接器的印制电路板，可以将插入I/O模块的各插槽连接起来，插槽的上下边可以使插入的模块排成一条直线。带有I/O模块和处理器的导轨被称为本地I/O导轨；140CPU31110
带有I/O模块、电源、远程I/O通信卡并且安装在远离本地I/O导轨的导轨被称为远程I/O导轨。远程I/O导轨的数目取决于不同处理器能够控制变量的数目。

I/O模块是Input/Output模块的缩写，140CPU31110 通常用于实现计算机与外部设备之间的数据传输和通信。不同类型的I/O模块可能具有不同的接口和功能，例如模拟量I/O模块、数字量I/O模块、组合I/O模块等。I/O模块在工业自动化、机器视觉、控制柜、成套电气等领域中均有广泛应用。

I/O modules can be divided into discrete, analog and special modules and other types, 140CPU31110
Modules can be mounted on rails or racks with multiple slots, one of which is inserted into each module. The guide rail or rack has different specifications, and the number of slots is divided into 4, 8, 12 and so on. Under normal circumstances, the power module is inserted in the first slot, the number is 0, the PLC is inserted in the second slot, and various types of input and output modules are inserted in the remaining slots. A printed circuit board with connectors is installed on the back of the I/O module rail to connect the slots for inserting the I/O module. The upper and lower parts of the slots allow the inserted modules to line up. Rails with I/O modules and processors are called local I/O rails; 140CPU31110
A rail with an I/O module, power supply, remote I/O communication card and mounted away from the local I/O rail is called a remote I/O rail. The number of remote I/O rails depends on the number of variables that different processors can control.

I/O module is the abbreviation of Input/Output module, 140CPU31110
It is usually used to realize data transmission and communication between computers and external devices. Different types of I/O modules may have different interfaces and functions, such as analog I/O modules, digital I/O modules, combined I/O modules, etc. I/O modules are widely used in industrial automation, machine vision, control cabinets, complete electrical equipment and other fields.
