中间继电器,TRS 24VDC 2CO AU,1123730000,Weidmueller

笔者参与的半导体设备的电气设计中，机台内由于分布着大量的液路管道，为了检测漏液情况，需在液路管道的关键位置布置大量的漏液传感器，机台使用的漏液传感器是NPN输出，漏液传感器信号接入到远程从站模块上（NPN低电平有效），软件平台进行采集，当发生漏液时及时切断管路阀门，软件平台控制一些液路阀门关闭。除此之外，为了避免软件平台死机，漏液时无法切断阀门等异常情况，特配置了一套独立与软件控制平台的安全控制系统，漏液传感器需另分出一路信号接入到安全控制器的拓展输入模块上，而安全控制器输入模块为PNP高电平输入有效。

因此，需要利用中间继电器将漏液信号分成两路信号，一对触点公共端为0V接入到远程从站模块，另一对触点公共端为24V接入到安全输入模块，之前使用的中间继电器型号为欧姆龙的MY2N-GS 24VDC继电器以及PYFZ-08-E插座，由于整个机台配置了大量的漏液传感器，而每一漏液传感器配置一个中间继电器，此时，就会有大量的中间继电器需要安装布局接线，而欧姆龙单个中间继电器横向宽度占用空间较大，完整继电器的宽高深尺寸约为23/72/67mm，当大量的中间继电器布局时，就会占用大量的空间，此外，每个中间继电器的公共端都需要接线，费时费力。因此，笔者在新设计方案时重新选择一款接线简单、占用空间小的中间继电器，基本要求：控制电压24VDC，2对转换触点，具有一定的接线便捷性，尽可能占用空间小。

图2 欧姆龙继电器应用图

魏德米勒提供多种类型的中间继电器，可满足不同客户的使用需求。TERM系列继电器模块是魏德米勒采用紧凑端子设计的解决方案。笔者选择了一款采用螺钉联接，镀金触点的中间继电器——TRS 24VDC 2CO AU（订购号1123730000），额定控制电压24 V DC ±20 %，额定切换电压/电流(AC)为250 V / 8 A，2对转换触点，宽高深尺寸为12.8/89.6/87.8mm，结构十分紧凑，可满足笔者的应用要求。同时，该继电器触点镀金，延长了使用寿命，其工作寿命高达30 x 10⁶次循环周期，工作温度为-40 °C—+60 °C，并具有UL、ROHS、CE多种国际认证。

从图3可以看出，魏德米勒的继电器在宽度上的优势明显优于欧姆龙的，该型继电器宽度仅有12.8mm，节省空间，特别当大量使用继电器时，优势将更加明显。TRS 24VDC 2CO AU还有一个较大优势就是接线特别方便，该型继电器可提供多种附件，包括供电模块以及横联件，当大量继电器并排布局，可选用供电模块，利用横联件将控制线圈的或者触点的公共端级联起来，使得接线更加简单快捷。

【应用】魏德米勒RSMB-08R0DD-XLDSMBWS 8位数字量输出接口板用于全自动焊接机，节省电气柜安装空间

从接线方式、负载、触点类别、线圈控制电压等参数来看，其电气性能无差别，所以8位的RSMB-08R0DD-XLDSMBWS接口板完全可以替代8个常规的中间继电器。相对数量较多中间继电器的应用场合，使用Weidmueller魏德米勒的8位数字量输出接口板可以减少中间接线环节，更能节省电气柜安装空间。
