Last updated Aug 17, 2026

When a legacy RS-232 serial device has to talk to a PROFIBUS DP control network, the fieldbus gateway is the bridge that makes the conversation possible. The WENGLOR ZAG73AN02 FIELDBUS GATEWAY BH0229 is built specifically for that RS-232 to PROFIBUS DP conversion, and with a listed price of USD 361.20, it is worth a careful look before you commit.

Quick verdict

The Wenglor ZAG73AN02 is a focused industrial networking fieldbus gateway that converts RS-232 serial communication into PROFIBUS DP. It is offered as new open-box, which is the main condition to weigh. The price sits at USD 361.20, and the model number ZAG73AN02 makes it easy to confirm you are ordering the specific Wenglor part you need.

Who it suits

This gateway suits anyone managing industrial automation equipment where an older RS-232 device needs to feed data into a PROFIBUS DP network. It is also practical for maintenance teams that want to keep legacy serial machines connected without replacing them with newer fieldbus-native hardware.

What stands out

The single job here is clear: RS-232 to PROFIBUS DP. That makes the ZAG73AN02 a targeted solution rather than a multi-protocol universal gateway. The Wenglor branding and the specific ZAG73AN02 model number give you a defined part to plan around, which is valuable when you are mapping out an industrial networking fieldbus installation.

Meaningful trade-offs

At USD 361.20, this is not an inexpensive accessory, so the buying decision comes down to whether you specifically need RS-232 to PROFIBUS DP translation. The unit is offered as new open-box, so if your procurement policy requires sealed packaging, that is the main consideration. The supplier for this unit notes over 20 years in the industrial components business, which adds some reassurance for sourcing a hard-to-find part.

This is the item under review. It is priced at USD 361.20 and offered as new open-box. Its core function is converting RS-232 serial signals to PROFIBUS DP, which is the key reason to choose it. The trade-off is the open-box condition: if your project requires a sealed unit, this may not be the right match. Otherwise, the precise ZAG73AN02 model identifier helps you confirm you are sourcing the intended Wenglor gateway for your industrial networking fieldbus setup.

Bottom line

If your network has a legacy RS-232 device that needs to join a PROFIBUS DP control network, the Wenglor ZAG73AN02 at USD 361.20 is a straightforward candidate. Accept the new open-box condition and you have a clearly defined gateway for the job.
