When you're choosing an industrial networking fieldbus gateway, the Moxa MGATE 4101-MB-PBS and Moxa 4101-MB-PBS look like twins. Both are fieldbus gateways and appear under the same product classification. The easy part is the price: one is USD 100 more than the other. The less obvious part is which unit's specs line up with your control network.
Quick verdict: The 4101-MB-PBS is the straightforward pick for shoppers who want the lower listed price and a title that clearly includes the data rate. The MGATE 4101-MB-PBS is worth considering if you prefer the MGATE part number and want the interface and power input details.

Product notes
MGATE 4101-MB-PBS
The MGATE 4101-MB-PBS is the higher-priced option in this head-to-head at USD 969.00. It is a 1-port fieldbus gateway in open-box condition, with 12-48VDC power and RS-232/422/485 serial interface details. If your control cabinet runs on that voltage range and you need standard serial signaling, this unit fits that scenario. The MGATE prefix also sets this part number apart from the other option, which may align better with your equipment documentation. The main trade-off is the USD 100 price gap between the two. The other product's title includes the 230.4 Kbps figure, so if that data rate is essential to your network, you'll see it clearly labeled on the 4101-MB-PBS.
4101-MB-PBS
The 4101-MB-PBS is the lower-priced option at USD 869.00. It is a 1-port fieldbus gateway with a title that explicitly includes the 230.4 Kbps data rate. It is also identified as a Modbus-to-ProfiBus slave gateway, which clarifies the intended protocol role. It also includes an operating temperature range of 0 to 55°C and the term 'drop-in module'. Like the other option, it is open box and from Moxa. The trade-off is that the part number omits the MGATE prefix, so if your inventory system expects that prefix, you may prefer the pricier option. For a 1-port fieldbus gateway at a lower listed price with the data rate clearly called out, this is the unit to start with.
Final choice by use case
Choose MGATE 4101-MB-PBS when: the serial interface and power input details match your cabinet, and you prefer the MGATE prefix in the part number.
Choose 4101-MB-PBS when: you want the lower listed price and a title that specifies the data rate, especially if you're working with a Modbus-to-ProfiBus slave gateway setup.
