德国PILZ安全继电器,安全开关,技术参数
皮尔兹安全继电器主要有两个作用:一是隔离作用;二是增加辅助接点.在实际应用中增加接点比较少,因为现在的接触器可以另加很多对辅助接点,而且动作也可靠,所以没有必要在一般控制日路中增加辅助继电器.而隔离作用在目前的控制中用得是比较多的.笔者以为主要有两个方面的隔离:一是将一个控制回路分隔为两个甚至更多的相对独立的回路;二是将强电量的模拟信号通过中间继电器转化为开关量侑源或无源).这里强调的不是这些继电器的作用,而是要通过工程实例,对中间继电器应用中的技术问题做出分析及提出解决的对策.
安全继电器顾名思义要安全,它是一个安全回路中所必须的控制部分(安全回路包括安全输入,控制器,安全输出),安全继电器接受了安全输入(比方说安全光幕、安全门锁)通过内部回路的判断,确定性的输出开关信号到设备的控制回路里.它的输入输出一般都是冗余的,并且触点都是强制导向的开关.
其实安全继电器说白了就是把2-4个继电器混在了一起,各自的触点很多是互锁的,这样就可以有效地监控外部回路的触点是否熔接,或者有没有短路等现象.
而PILZ安全继电器可以监控功率、电流、电压、接地故障、相位序列;同时也可以用来控制急停、安全门、光栅、安全地毯、双手控制等,而且PILZ安全继电器操作简便、产品部件符合国际标准与规范(如EN954-1)而且通过Z少一家以上的机构测试,并予以认证.带有插入终端的单元,可确保更快的试运行,有Z小的空间,有Z高的安全等级,极好的性价比,通用电源的低存储成本.可用于所有安全功能,如监控紧急停止,安全门,光栅等.
皮尔兹安全继电器工作特性:
作为控制元件,继电器有如下四个特点:皮尔兹安全继电器工作原理及技术参数
1)扩大控制范围.例如,多触点继电器控制信号达到某一定值时,可以按触点组的不同形式,同时换接、开断、接通多路电路.
2)放大.例如中间继电器等,只用一个很微小的控制量,
就可以控制很大功率的电路.
3)综合信号.例如,当多个控制信号按规定的形式输入多绕组继电器时,经过比较综合,达到预定的控制效果.
4)自动、遥控、监测.例如,自动装置上的继电器与其他电器一起,可以组成程序控制线路,从而实现自动化运行.皮尔兹安全继电器工作原理及技术参数
4 皮尔兹安全继电器应用实例:以胶带机的自动控制为例,介绍中间继电器的隔离作用
工作原理是将一个输入信号变成一个或多个输出信号的电子元件.它的输入信号为线圈的通电或断电.它的输出是触头的动作(所带常开点闭合,常闭点打开),它的触点接在其他控制回路中,通过触点的变化导致控制回路发生变化(例如导通或截止),从而实现既定的控制或保护的目的.在此过程中,继电器主要起了传递信号的作用
