How much is the CPU for the S7 300? How much does each of the corresponding modules (analog and digital) cost? How many dots are there on a module? Thank you

The question is too vague! The price of CPUs also varies depending on the model; on average, it’s around 40,000 yuan for lower-end models. The more affordable options cost around 18,000 yuan. The common number of processing units is 16, but options with 32 units are also available. Analog quantities are generally based on 8 points, though there are also those with 4 points.

So, it’s because you’re an outsider – CPUs are so expensive; I thought a few thousand would be enough

The CPUs in the S7-300 series are already quite excellent; selling them at rock-bottom prices would be a disservice to this brand!

The price on the 2nd floor is too high; with your price, one can buy a CPU worth 400. There are many CPU models available at 300, and the most commonly used one is the CPU315-2DP (there’s also another version with an Ethernet port). Its price is around 10,000 or so (prices keep rising year by year). DI/DO modules usually have 16 inputs/outputs (some also have 32), and those with 16 inputs/outputs cost less than 2,000. AI modules typically have 8 channels, with prices around 4,000. AO modules generally have 4 channels (some also have 8), and their prices are around 4,000 as well

Siemens has achieved the best combination of quality and price in the field of automatic control. Don’t hesitate or waver – choosing Siemens is the right decision. If you think it’s too expensive for a domestic brand, then go with a domestic brand for industrial control purposes; among them, Siemens is by far the best

I also based it on our previous price estimates; perhaps the procurement channels are different. What we purchase is 100% the most expensive and highest quality items; we do not source from certain channels. That’s why I’ve estimated a higher price! It might be cheaper if you go to Taobao!

Guys upstairs, would you like to make purchases from me?

If purchasing at Siemens’ listed price, then I have nothing to say. In fact, Siemens offers significant discounts on its PLCs, usually around 50% off; the exact discount rate depends on the distributor. Moreover, for larger projects, it is possible to request special discounts from Siemens

It seems like an expert! I really am not as you think!
