IS430SNUAH1A 本地I/O导轨只带有I/O模块和处理器

I/O模块，即输入输出模块，是控制系统中的重要组成部分。IS430SNUAH1A可分为离散、模拟和特殊模块等多种类型，这些模块都可以安装在带有多个插槽的导轨或者机架上，每个模块插入其中一个插槽。这些插槽的数目通常有4、8、12等不同的规格。

在一般情况下，电源模块会插在第一插槽内，编号为0，PLC插在第二插槽内，各种类型的输入输出模块则插在其余插槽内。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，使插槽的上下边可以使插入的模块排成一条直线。

此外，I/O模块还分为本地I/O导轨和远程I/O导轨。本地I/O导轨只带有I/O模块和处理器，而远程I/O导轨则带有I/O模块、电源、远程I/O通信卡，并且安装在远离本地I/O导轨的位置。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。

并行I/O模块 FLEX数字量I/O模块按其功能可以分为带保护输出型、带电子保险型、带自诊断型和隔离型。

另外，IS430SNUAH1A在分布式I/O系统中，I/O模块是必备组件，需要与合适的耦合器（例如BL200系列）组合才能将现场设备或过程连接起来，实现对现场数据采集、监视和控制。

I/O module, that is, input and output module, is an important part of the control system. The IS430SNUAH1A can be divided into discrete, analog and special modules, which can be mounted on a rail or rack with multiple slots, each module inserted into one of the slots. The number of slots is usually 4, 8, 12, and so on.

Under normal circumstances, the power module will be inserted in the first slot, the number is 0, the PLC is inserted in the second slot, and the 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 guide rail to connect the slots inserted into the I/O module, so that the upper and lower parts of the slots can make the inserted modules line up.

In addition, I/O modules are also divided into local I/O rails and remote I/O rails. The local I/O rail has only the I/O module and processor, while the remote I/O rail has the I/O module, power supply, remote I/O communication card and is installed away from the local I/O rail. The number of remote I/O rails depends on the number of variables that different processors can control.

The parallel I/O module FLEX digital I/O module can be divided into protected output type, electronic insurance type, self-diagnostic type and isolation type according to its function.

In addition, in the distributed I/O system, the I/O module is a necessary component, and it needs to be combined with a suitable coupler (such as the BL200 series) to connect the field equipment or process to achieve the field data acquisition, monitoring and control.
