Our current project involves discussing the upgrade of a customer's machine's Programmable Logic Controller (PLC) and Human Machine Interface (HMI) which is scheduled for next Fall. However, a month ago, the customer's SLC 5/05 experienced a crash and we replaced it with a back-up CPU. Now, the customer has requested a back-up CPU in case of another failure before the scheduled upgrade. I recall a cautionary discussion on the risks of purchasing SLCs from online platforms like Ebay. Despite the customer's preference to avoid products from China, it is important to note that the issue goes beyond just that. Attached is an image of the current CPU for your reference. Can you provide any specific details to consider while sourcing a 1747-L552 CPU for our buyer?
If you're looking for the most dependable option, purchasing a brand new unit is your best bet, despite the higher cost. These units are nearing the end of their product life cycle and will no longer be available after 3/31/2024, with a price tag of nearly $16,000. It's recommended to consider sourcing from a reputable US-based company like Radwell, which offers warranties for added peace of mind. Remember to conduct thorough testing as soon as you receive the unit to ensure its functionality.
When purchasing critical spares, it's recommended to buy from a trusted refurbisher like Radwell.com for warranties, certified products, and genuine items. Although the price may be higher, customers can have peace of mind knowing they are getting quality products. Additionally, there are reliable members within the community who sell used parts that you can consider as well.
If I were to purchase a similar item from Ebay, my first step would be to switch it out and use the current one as a backup. Instead of choosing Radwell, I prefer to support a trusted brand like Allen Bradley 1747-L552 /C FRN 13 Ethernet Series C 5/05 SLC500 32k Mem PLC.

dmroeder mentioned that if they were to purchase a similar item on eBay, their first action would be to replace it and retain the current one as a backup. They prefer supporting a trusted source like Allen Bradley 1747-L552 /C FRN 13 Ethernet Series C 5/05 SLC500 with 32k Mem PLC. For reliable PLC cables, trainers, and industrial automation supplies, they recommend visiting www.plccable.com. They also added that they always choose to buy from Mark whenever possible and will advise their office to reach out to him.
Sourcing a 1747-L552 CPU can indeed be tricky, especially given the prevalence of fake or substandard components on the open market. One important thing to consider is to source from a reputable dealer, even if the cost may be slightly higher. This can assure quality, warranties, and the much-needed technical support in case of any issue. It's also useful to verify the date of manufacture - you'd want a relatively recent one to minimize the risk of failures. Additionally, make sure the component comes with the necessary firmware, as there can be compatibility issues with the wrong version. In essence, focus on quality and reliability of the source instead of just the price.
Purchasing a 1747-L552 CPU via online platforms can indeed be risky, especially considering the high number of counterfeit products in the market. Aside from the country of origin, I suggest distinguishing between genuine and fake products by scrutinizing the product's labels, finishes, and documentation. Additionally, it would be best to stick to trusted and reputable resellers who are knowledgeable about the product and can provide a warranty or after-sales service. It may be slightly more expensive, but it should ensure some peace of mind and potentially save you from crippling system failures in the long run. Always remember, if a deal seems too good to be true, it probably is.
