1、输入类型的分类

PLC的数字量输入端子，按电源分直流与交流，接输入接口分类由单端共点输入与双端输入，单端共点接电源正极为SINK(sink Current 拉电流，单端共点接电源负极为SRCE(source Current 灌电流)。

2、词语的概述

SINK漏型为电流从输入端流出，那么输入端与电源负极相连即可，说明接口内商的光电超合器为单端共点为电源正极，可接NPN型传感器SOURCE源型为电流从输入端流进，那么输入端与电源正极相连即可，说明接口内部的光电羯合器为单端共点为电源负极，可接PNP型传感器接近开关与光电开关三、四线输出分 NPN 与 PNP 输出，对于无检测信号时 NPN 的接近开关与光电开关输出为高电平(对内部有上拉电阻而言)，当有检测信号，内部NPN 管导通，开关输出为低电平.

1. Classification of input types

The digital input terminal of PLC is divided into DC and AC according to the power supply, and the input interface is classified by single-ended common input and double-ended input. The single-ended common input power supply is positively SINK(sink Current), and the single-ended common point power supply is negatively SRCE(source Current).

2. Overview of words

SINK drain means that the current flows out of the input end, then the input end is connected to the negative electrode of the power supply, indicating that the photoelectric superjunction inside the interface is single-ended common point is the positive electrode of the power supply, and the NPN sensor can be connected. SOURCE source means that the current flows in from the input end, then the input end is connected to the positive electrode of the power supply, indicating that the photoelectric junction inside the interface is single-ended common point is the negative electrode of the power supply. PNP type sensor proximity switch and photoelectric switch three, four wire output points NPN and PNP output, for no detection signal when the NPN proximity switch and photoelectric switch output is high (for internal pull-up resistance), when there is a detection signal, the internal NPN tube is on, the switch output is low.
