TRICONEX 9563-810 数字量输入接线板

数字量界说为:在时刻和数值上都是断续改动的离散信号。基本的数字量就是0和1,反映到开关上就是指一个开关的断开是(0) 或接通是(1) 情况。

plc的数字量模块用来检测数字信号,常用的是开关量(凹凸电平)输入，输出;如按钮接数字量输入模块,线圈接数字量输出模块。模拟量界说为:在时刻和数上都是连续改动的信号例如经各类传感器或变送器传送过来的电压、电流、温度,频率等信号,即模拟量，一般在PLC用的是0(或4)安~ ~20安, -10(或0)V~ ~ +10V等。PLC的模拟量模块用来检测或许输出电压或电流信号，比方用来检测温度,励等信号的为模拟量输入模块，经过调度输出电流或许电压来调度操控阀门的敞开度用到模拟量输出模块。

The definition of a digital quantity is a discrete signal that undergoes intermittent changes in both time and value. The basic numerical quantities are 0 and 1, reflected on a switch, which refers to whether a switch is off (0) or on (1).

The digital module of PLC is used to detect digital signals, and commonly used are the input and output of switching values (concave convex level); If the button is connected to a digital input module, and the coil is connected to a digital output module. Analog quantity is defined as a signal that continuously changes both in time and number, such as voltage, current, temperature, frequency, and other signals transmitted through various sensors or transmitters. Analog quantity is generally used in PLC, ranging from 0 (or 4) A to 20 A, -10 (or 0) V to+10V, etc. The analog module of PLC is used to detect or output voltage or current signals. For example, the analog input module is used to detect temperature, excitation, and other signals. After scheduling the output current or voltage to control the opening of the valve, the analog output module is used.
