【应用】宽度仅12.8mm的中间继电器TRS 24VDC 2CO AU用于半导体设备，提供供电模块等多种附件使得接线便捷
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。

【选型】魏德米勒10A手指保护继电器助力锂电池搅拌设备， 认证齐全，可抑制浪涌电流达20A/50ms
某客户在研发锂电池搅拌设备，二次控制回路需要插拔式中间继电器进行信号转换，本文推荐使用魏德米勒手指保护继电器DRM270024LT，整体2路转换触点，带蓝色测试按钮，方便判断继电器的好坏状态；继电器和底座都有CE，UL认证，产品适合出口欧美市场。
【经验】在远程IO模块输出点与设备信号灯之间增加中间继电器，解决远程IO无信号输出时信号灯微亮异常
三极管在上电后会有微弱的漏电流几乎很难避免，为了消除这个微弱的漏电对指示灯的工作状态影响，在远程IO模块的对应输出点与信号灯之前增加了魏德米勒（Weidmueller）中间继电器（7760054273），因为中间继电器的线圈驱动电压为24V。
【选型】继电器模块DRM270024LT助力直流充电桩，抗震动，耐浪涌电流20A
某客户研发直流充电桩，电气控制柜内需要用导轨安装中间继电器。根据需求，本文推荐内置魏德米勒（Weidmueller）继电器模块的完整方案，抗震动，耐浪涌电流20A，含CE、UL、ROHS认证。
【应用】超薄继电器TRS 24VDC 2CO用于激光打标机，宽度只有为12.8mm，可替换欧姆龙MY2N
一般激光打标机没有专门的配电柜，电气部件都是安装在机器内部，安装空间有限，所以客户要求设备内部的部件越紧凑越好。客户原来有使用欧姆龙MY2N系列的2路转换触点的DC24V 5A中间继电器，为了节省安装空间，推荐魏德米勒DC24V 6A超薄继电器TRS 24VDC 2CO，其宽度只有为12.8mm，在相同负载下，机械寿命更长，触点机械寿命高达200万次以上，可有效的减少更换成本。
