PLC体积小,重量轻,易于安装。 PLC的输入输出系统可以直观地反映现场信号的变化状态,可以通过方式直观地反映控制系统的运行状态,如内部工作状态,通信状态,I / O点状态,异常状态,和电源状态。有一些引人注目的说明,这对操作和维护人员监控系统非常有利。1747-L542罗克韦尔PLC
供应可编程控制器的输入信号类型可以是开关量、模拟量和数字量。一般来说,输入单元由两部分组成:一部分是与被控制设备相连的接口电路,另一部分是输入图像寄存器。
输入单元接收来自用户设备的控制信号,如限制开关、操作按钮、选择开关、跳转开关和其他传感器。通过接口电路,这些信号被转换成处理器能够识别和处理的信号,与输入的图像寄存器共存。运行时cpu从输入图像寄存器中读取输入信息并对其进行处理,将处理结果存储在输出图像寄存器中。
为了防止干扰信号和高压信号进入PLC,影响其可靠性或造成设备损坏,现场输入接口电路一般采用光电耦合电路隔离。光电耦合电路的关键器件是光耦合器,通常由发光二管和光电晶体管组成。1747-L542罗克韦尔PLC通常PLC输入类型可以是DC(DC24V),AC和AC和DC。输入电路的电源由外部提供。有些也可以由PLC内部提供。对于DC输入,根据场输入接口电路的形式,它分为两种类型:源输入和宿输入。绝大多数欧洲和美国的PLC使用泄漏输入,而绝大多数亚洲的PLC使用源输入。
