Choosing a fieldbus gateway often comes down to a simple question: do you pay more for a new, fully warrantied unit, or do you take a chance on a used one that fits your budget? For shoppers looking at the Burkert 00307390 / ME43 Industrial Ethernet Fieldbus Gateway, the listed price is USD 249.99, and the condition is clearly marked as used.
This article walks through what this specific unit offers, who it suits, and what to keep in mind before you commit.
Quick verdict
If your project already depends on Burkert's ME43 protocol conversion and you are comfortable with a used industrial component, the Burkert 00307390 / ME43 at USD 249.99 is a straightforward way to get the gateway onto your network. The description says the unit is a working pull and will come as pictured, so the purchase decision rests on whether you can accept a pre-owned module as-is.
Who it suits
This gateway makes sense for buyers who need an Industrial Ethernet fieldbus gateway for a Burkert-based system, who have the surrounding equipment already, and who are comfortable with the used condition. The product is identified by the model name ME43 and part number 00307390.
What stands out from the listed details
The most useful detail here is that the seller explicitly identifies the unit as a working pull. That means the unit was removed from a working context rather than sold as damaged or for parts, though the used condition means you should inspect all images carefully. The price, USD 249.99, is a concrete figure you can compare against new Burkert ME43 options or other used Industrial Ethernet fieldbus gateways.
Burkert 00307390 / ME43 Industrial Ethernet Fieldbus Gateway Used

Choose this used gateway if you want a direct path to the ME43 protocol conversion without paying new-unit prices. The working-pull description gives you a specific basis for your decision, and the unit comes as pictured so you know exactly what arrives.
The built-in trade-off is the used condition itself: it is a pull, not a new unit, so expect normal signs of service based on the photos. If you are not comfortable with a pre-owned component in your network, this is the main point to weigh.
Meaningful trade-offs
The main trade-off is between price and certainty. You are paying a set, clear amount for a used ME43. But because the condition is used, the photos matter more than they would for a new unit. The description says it will come as pictured, so compare each image with what you see in your own setup.
Bottom line
If you need a Burkert ME43 Industrial Ethernet Fieldbus Gateway and can work with a used component, this unit offers a named model, a working-pull description, and a concrete price point. Review the images carefully, confirm it fits your network's protocol needs, and decide whether used is the right path for your project.
