HESG324013R100 输出模块  可以输出信号

【产品详情】

输入输出模块也称为控制模块，在有控制要求时可以输出信号，或者提供一个开关量信号，使被控设备动作，同时可以接收设备的反馈信号，以向主机报告，是火灾报警联动系统中重要的组成部分，市场上的输入输出模块都可以提供一对无源常开/常闭触点，用以控制被控设备，部分厂家的模块可以通过参数设定，设置成有源输出（如海湾GST-LD-8301),相对应的还有双输入输出模块、多输入输出模块等等。

(1)模拟量输入模块

模拟量输入模块也称为A/D模块，它将从各种工业现场传感器中采集的模拟量信号转换成CPU可以识别接收的数字量。

(2)模拟量输出模块

模拟量输出模块又称为D/A模块，简单来说就是将模拟量输入模块CPU送来的数字量转换成其他外部设备1识别接收的电压或者电流等信息。

(3)数字量模块

数字量模块的主要作用就是检查外部开关输入的状态。数字量输入输出信号是开关量信号，1或者0。

二、模拟量模块的作用

1、模拟量输入模块的主要作用是收集模拟信号。收集外部压力传感器后，在模块内部收集压力传感器收集的模拟信号，并进行相应的处理。这里的传感器数据包括电压、电流、热阻、热电偶、温度等模拟值，然后通过总线传输给计算机的智能模块。

2、模拟量输出模块的作用是通过数模转换输入的数字信号进行转换，输出可控制的连续电流和信号。

3、数字量模块：数字量模块有输入输出两种功能。如果不采用这种方法集成，可以节省更多空间，否则用户在使用时需要买两个模块，数字量模块解决了这一问题，即：集成输入/输出功能，一个模块既可以输入信号也可以输出信号。

【英文介绍】

Input/output module is also known as the control module, when there are control requirements can output signals, or provide a switching signal, so that the controlled device action, at the same time can receive the feedback signal of the device, to report to the host, is an important part of the fire alarm linkage system, the input/output module on the market can provide a pair of passive normally open/normally closed contacts. In order to control the controlled equipment, some manufacturers' modules can be set to active output (such as Gulf GST-LD-8301) through parameter setting, corresponding to double input output module, multi-input output module and so on.

(1) Analog input module

The analog input module, also known as A/D module, converts analog signals collected from various industrial field sensors into digital quantities that the CPU can recognize as received.

(2) Analog output module

The analog output module is also called the D/A module, which is simply to convert the digital quantity sent by the analog input module CPU into other external devices 1 to identify the received voltage or current and other information.

(3) Digital module

The main function of the digital module is to check the status of the external switch input. The digital input/output signal is a switching signal, 1 or 0.

Second, the role of analog module

1. The main function of the analog input module is to collect analog signals. After collecting the external pressure sensor, the analog signal collected by the pressure sensor is collected inside the module and processed accordingly. Here the sensor data includes voltage, current, thermal resistance, thermocouple, temperature and other analog values, and then transmitted to the intelligent module of the computer through the bus.

2, the role of the analog output module is to convert the input digital signal through the digital-to-analog conversion, and the output can be controlled continuous current and signal.

3, digital module: digital module has two functions: input and output. If you do not use this method of integration, you can save more space, otherwise the user needs to buy two modules when using, the digital quantity module solves this problem, that is, integrate the input/output function, a module can both input signals and output signals.
