An industrial networking fieldbus gateway is the translator between fieldbus devices and an Ethernet control network, but choosing one quickly becomes a question of protocol labels, condition, and listed price. The four options here range from a new Invertek Ethernet IP module at the lower end of the price spread to a used Delta Tau CAN/PROFIBUS interface card at the top, with a Softing PROFIBUS/Ethernet gateway and a Burkert industrial Ethernet gateway in between.
Quick Take
If your search starts with PROFIBUS-to-Ethernet, the Softing FG-100-PB is the only listing that names that connection path in its title. If you want a new Invertek module and a lower listed price, the Invertek OPT-2-ETHEG-IN is the new-condition pick. If the manufacturer matters, the Burkert 00307390 / ME43 is the option tied to the Bürkert name. If you need a CAN/PROFIBUS interface card, the Delta Tau ACC-72E is the listing that carries that label, though it is used and sits at the top of the price range.
Listed Price Comparison at a Glance
The listed prices run from USD 152.98 to USD 404.99. The table below shows each option with a relative bar.
| Listed Option | Listed Price | Price Bar |
|---|---|---|
| Softing FG-100-PB Fieldbus Gateway PROFIBUS/Ethernet, 1 Channel | USD 233.89 | |
| Burkert 00307390 / ME43 Industrial Ethernet Fieldbus Gateway Used | USD 249.99 | |
| Invertek OPT-2-ETHEG-IN Ethernet IP Fieldbus Gateway Module | USD 152.98 | |
| Delta Tau ACC-72E Fieldbus Gateway CAN/PROFIBUS Interface Card | USD 404.99 |
Quick Choice Guide
- PROFIBUS/Ethernet gateway: The Softing FG-100-PB title calls out PROFIBUS/Ethernet and a 1-channel gateway. It is listed as new-open-box.
- Ethernet IP module: The Invertek OPT-2-ETHEG-IN is described as an Ethernet IP fieldbus gateway module and a PLC Ethernet Module, and it is new.
- Bürkert industrial Ethernet gateway: The Burkert 00307390 / ME43 is listed as an Industrial Ethernet Fieldbus Gateway and carries the Bürkert name.
- CAN/PROFIBUS interface card: The Delta Tau ACC-72E is described as a fieldbus gateway CAN/PROFIBUS interface card and is used.
Product Notes
Softing FG-100-PB Fieldbus Gateway PROFIBUS/Ethernet, 1 Channel
This is the listing that states the PROFIBUS/Ethernet connection in the product name, and the 1 Channel wording clarifies the scale of the gateway. It is listed at USD 233.89 in new-open-box condition. The open-box status is the limitation to weigh: the unit is new, but the box has been opened, so the sealed-box expectation does not apply. The FG-100-PB part number gives you a precise reference for cross-checking against your project's expected part.
Burkert 00307390 / ME43 Industrial Ethernet Fieldbus Gateway Used
The Burkert listing connects the ME43 model number directly to the phrase Industrial Ethernet Fieldbus Gateway. For a buyer who wants the Bürkert manufacturer name on this type of component, the 00307390 / ME43 is the clear match. The used condition is the main limitation, and the listing describes the unit as a working pull. At USD 249.99, this sits in the middle of the listed prices. The model number is part of the product name, making part-number verification easy.
Invertek OPT-2-ETHEG-IN Ethernet IP Fieldbus Gateway Module
The Invertek OPT-2-ETHEG-IN is the new-condition option and the lowest listed price in this group at USD 152.98. Its title describes an Ethernet IP fieldbus gateway module, and the listed type is PLC Ethernet Module, so the product is framed around the Ethernet side of a fieldbus connection. The limitation is that the name does not advertise a CAN or PROFIBUS bus-side interface. If you are specifically shopping for a CAN/PROFIBUS gateway, the title will not confirm that match. For a lower listed price and a new module, this is the strongest candidate.
Delta Tau ACC-72E Fieldbus Gateway CAN/PROFIBUS Interface Card
The Delta Tau ACC-72E is the listing that puts both CAN and PROFIBUS into the product title, which makes it easy to find if those are the bus names on your spec. It is used, and it carries the highest listed price in this set at USD 404.99. The part number ACC-72E is specific, and the title positions it as a fieldbus gateway interface card. The used condition and the top-of-range price are the two factors to balance against the CAN/PROFIBUS designation. This is the option to evaluate when that exact bus combination is what you are searching for.
Final Recommendation by Use Case
Pick the Invertek OPT-2-ETHEG-IN if you want a new module at the lowest listed price in this group. Pick the Softing FG-100-PB if your search is specifically for a PROFIBUS/Ethernet gateway and you can accept a new-open-box listing. Pick the Burkert 00307390 / ME43 if the Bürkert name and Industrial Ethernet Fieldbus Gateway label are the decision points. Pick the Delta Tau ACC-72E if the CAN/PROFIBUS interface card label is exactly what you need, understanding that this option is used and priced higher than the others.
