When you need a fieldbus gateway for an industrial networking setup, the choice usually comes down to how much detail you need out of the box and how much you can spend. On one side is the Moxa MGATE 4101-MB-PBS, an open-box 1-port unit priced at $969.00, with specifications that include RS-232/422/485 serial interfaces and a 12-48VDC input range. On the other is the Burkert 00307390 / ME43, a used industrial Ethernet fieldbus gateway at $249.99, described as a working pull. The price spread is wide, and so is the difference in what the two listings tell you.
Quick Verdict
If your project calls for clearly stated serial connectivity and a wide DC power range, the Moxa gives you those details in writing. It costs more, but you know what you're getting. If you're comfortable with a used unit and want to minimize outlay, the Burkert is the less expensive choice.

Product Notes
Moxa MGATE 4101-MB-PBS
The Moxa MGATE 4101-MB-PBS is the higher-priced unit in this comparison, and it brings a fairly detailed spec sheet to the table. The title identifies it as a 1-port fieldbus gateway, and the listing adds support for RS-232/422/485 serial interfaces plus a 12-48VDC input range. That level of detail is helpful if you need to match a gateway to your existing industrial network. Since it's in open-box condition, the unit itself should be in working order even if the packaging isn't sealed. The main drawback is price: it costs much more than the Burkert, so it will be the right choice only if those explicitly listed specs are central to your application. For anyone who needs a gateway with known serial protocols and a flexible DC power window, this Moxa is the one that makes those features explicit.
Burkert 00307390 / ME43
The Burkert 00307390 / ME43 is the less expensive option and is described as a used industrial Ethernet fieldbus gateway and a working pull. That means it was removed from a working system and should still function as pictured. It's an appealing choice if you need to keep spending low or want a backup unit on hand without a large outlay. The listing focuses on the unit's condition and price, so you won't find the same level of technical detail that the Moxa listing includes. If your application doesn't require documented serial interface types or a specific DC power input, this used Burkert is a practical way to add fieldbus gateway capability while spending considerably less.
Final Choice by Use Case
Choose the Moxa MGATE 4101-MB-PBS when you need an open-box gateway with documented RS-232/422/485 and 12-48VDC support and you're prepared to pay for that clarity. Choose the Burkert 00307390 / ME43 when you're after a lower-cost used gateway and the technical details in its listing are sufficient for your setup. If price matters most, the Burkert is the pragmatic pick; if specification transparency matters most, the Moxa wins.
