1756-IR12输入模块主要用于接收信号输入，并将其作为系统的一部分。其根据输入信号的不同，可以分为开关量输入和模拟量输入两种类型。

开关量输入模块可以接收一个无源触点信号，并将其接入到系统中。这种模块通常用于接收水流指示器、压力开关、信号阀等设备的报警信号与反馈信号。市场上的输入模块有多种类型，包括只能接收常开信号输入的模块，可以通过参数设定接收常开或常闭信号输入的模块，以及双输入模块甚至是多输入模块等。

此外，1756-IR12输入模块在建设工程领域中也发挥着重要作用。在设计阶段，设计师可以使用输入模块来输入和编辑项目的基本信息，包括项目名称、地理位置、规模等。在施工阶段，施工人员则可以使用输入模块来记录施工过程中的关键信息，如材料使用情况、人员配置、进度等。

The 1756-IR12 input module is mainly used to receive signal input and use it as part of the system. According to the different input signals, it can be divided into switching input and analog input two types.

The switching input module can receive a passive contact signal and connect it to the system. This module is usually used to receive water flow indicators, pressure switches, signal valves and other equipment alarm signals and feedback signals. There are many types of input modules on the market, including modules that can only receive normally open signal input, modules that can receive normally open or normally closed signal input through parameter Settings, and dual-input modules or even multi-input modules.

In addition, the 1756-IR12 input module also plays an important role in the field of construction engineering. During the design phase, designers can use the input module to enter and edit the basic information of the project, including the project name, geographical location, size, etc. During the construction phase, the construction personnel can use the input module to record key information during the construction process, such as material usage, staffing, progress, etc.
