70EA02A-ES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。

70EA02A-ES模拟量输入模块则主要用于接收电流量或电压量信号。例如，一些厂家的非编码探测器在报警时会输出电流量信号，该信号可以被模拟量输入模块接收并输入到系统中。

The 70EA02A-ES 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.

The 70EA02A-ES analog input module is mainly used to receive current or voltage signals. For example, some manufacturers of non-coding detectors will output a current flow signal when the alarm, the signal can be received by the analog input module and input into the system.
