The Moxa MGate 5101-PBM-MN Series is an industrial-grade gateway that enables seamless protocol conversion between PROFIBUS DP-V1 and Modbus TCP. Acting as a PROFIBUS Master and Modbus TCP Client or Server, it allows legacy PROFIBUS slave devices to be integrated into modern Ethernet-based control networks quickly and reliably.

With AutoScan for PROFIBUS devices, HTTPS-secured web configuration, and advanced traffic diagnostics, it is ideal for use in industrial automation, oil & gas, power systems, and more. Redundant power inputs and relay output functionality ensure uninterrupted operation and proactive maintenance capability.
