您好，在这个视频报警信号模块中，Cygnus模块是扩展集成IO的输入输出模块。
Hello, in this video alert signal module, Cygnus modules are input and output modules which extend the integrated IO.

所以我们有 CPU，在 CPU 上我们有板载输入和板载输出。
So we have the CPU and on the CPU we have onboard inputs and on board outputs.

但是想象一下，您需要更多的输入和输出用于单元信号模块，而信号模块就是输入和输出模块的含义。
But imagine you need more inputs and outputs for unit signal modules and signal modules is meaning of input and output modules.

根据 CPU 版本的不同，CPU 右侧不能插入两个或八个模块。
Depending on the CPU version, either none two or eight modules can be plugged onto the right side of the CPU.

这意味着什么？
What does that means?

你有CPA和你的CPU右边的八个模块可以添加OK，它允许二到八个模块。
You have the CPA and right side of your CPU's eight modules can be added OK and it allows two to eight module.

使用海员的两米长延长电缆可以实现两层设计。
A two tier design is possible using a two metre long extension cable wire extension cables of your seamans.

OK to Matel 延长电缆可用于新的信号模块，但可使用的模块数量不会因此改变。
OK to Matel extension cable can be used for the a new signal modules and but the number of modules which can be used is not changed as a result.

所以我们有信号模块、数字输入、数字输出和数字输出模块。
So we have a signal modules, digital inputs, digital outputs and digital in an output module.

您可以在这里看到名称、模块名称和规格，或者添加到这些模块中的数字输入和输出数量。
And you can see in here the names, the module names and the specifications or how many digital inputs and outputs added to these ones.

例如AS和1223 D.C.，DC Digital In and out模块有8个数字量输入和8个数字量输出。
For example, AS and 1223 D.C., DC Digital In and out module has eight digital input and eight digital output.

好的，我已经完成这个视频了。
OK, I am finished for this video.

下一个视频见。
See you in the next video.
