Who knows what the performance of the card module in the Zhongkong XP351 is?

XP351 current signal input card, 8 channels, current signal, opto-isolated

Is there any slightly more detailed information, expert?

Take a look at this. :victory:

Thank you, handsome. By the way, do you have any information on the XP372? Hehe, thanks

Are you working in central control technology? Could we add each other on WeChat or QQ?

Please find the hardware documentation for XP372. I will reply as soon as possible if there are any issues. Sea rivers will do.

Thank you. I’m a beginner, haha; I’ve just started out, so I want to learn**

Could you please tell me how to determine the number of redundant cards, given the percentages for AI, AO, DI, DO, and redundancy? Do you have any information on how to perform this calculation? Thank you

I understand what you mean. It doesn’t seem to be expressed very reasonably. What you mean is: knowing the total score and the number of points that need to be covered by redundancy, how to determine the final number of cards required. I’m not sure if that’s what it means. The total number of cards is significant, as it allows for the direct calculation of prices, enabling price estimation and procurement. For this task, you can ask the control room staff to provide a quote; they have the calculation formulas. For details, see the attachment – you just need to enter the parameters you know, and the prices will be displayed in the table. Even without a table, you can still make your own rough estimate. But one needs to be familiar with the hardware of the central control system, as well as with power supply, network components, cabinets, and other common components. There are 4 parameters that need to be specified: 1. Total number of points; 2. Reserve ratio for points; 3. If expansion is considered, the available space in the cabinet should be indicated; 4. Number of redundant points. Once these details are available, you can proceed with drafting the technical specifications. Then, once the system manufacturer receives it, they can provide the hardware specifications and price.

Yes, it’s what you mentioned. It’s not expressed very clearly – is this a configuration table? What I want to ask is about the calculation formula. Hehe, could you please send me one like that? Let’s do some research, hehe, thanks
