1C31233G04 Emerson艾默生 输入输出模块 DCS卡件

产品描述

输入模块是PLC控制系统中的一部分，主要负责接收现场设备或控制设备的信息，并进行信号电平转换，然后将转换结果传送到CPU进行程序处理。

(1)数字量输入模块只能接收高低逻辑电平信号，如开关的接通与断开;

(2)模拟量输入模块可以接收连续变化的的模拟量信号，如温度传感器输出的DC 4-20mA电流信号。

Product description

The input module is a part of the PLC control system, which is mainly responsible for receiving the information of the field device or the control device, and converting the signal level, and then transmitting the conversion result to the CPU for program processing.

(1) The digital input module can only receive high and low logic level signals, such as switching on and off;

(2) The analog input module can receive continuously changing analog signals, such as the DC 4-20mA current signal output by the temperature sensor.
