计时器跳闸处于开启状态至少60秒

我认为你需要的是具有延时功能的一次性继电器，可以使你的闩锁跳闸。
也许像F10686-ND这样的方式即使使用长输入信号，您仍然可以让锁存器仅在编程（3秒）的时间内接收电源。
这是一篇解释它们如何运作的帖子。

时间继电器以及它们的功能如何能够非常快速地混淆。
下面是时间延迟继电器的一些更常见功能之间差异的非常概括的图表。
在查看产品时，请务必查看数据表，因为其中一些可能需要一致的电源以及输入或控制触点。
也可能会有一些轻微的变化，特别是当你只有闪光灯和重复循环等重复功能时。

        I think what you need would be a one shot relay with a time delay function that could trip your latch. Maybe something like F10686-ND That way even with the long input signal you can still have the latch only receive power for a programmed (3 Sec) amount of time.
Here is a post that explains how they function.
              Time Delay Relay Functions     

    Time relays and exactly how they function can get very confusing very quickly. Below is a very generalized chart of the differences between some of the more common functions of time delay relays. When looking at products, be sure to check out the datasheets as some of these might require consistent power along with the input or control contact. There also might be some slight variations as well, especially when you only have repeating functions like flashers and repeat cycles.  [Time Delay Rela…  

谢谢罗伯特我来到了同样的解决方案。
