INBACMEB1200000 – M-Bus to BACnet IP/MSTP Gateway for 3 000 Points & 120 Devices

INBACMEB1200000 – M-Bus to BACnet Gateway for up to 3 000 Points and 120 Devices. 

The INBACMEB1200000 gateway from Intesis by HMS enables seamless integration between M-Bus energy meters and BACnet-based control systems. This industrial-grade protocol converter supports up to 120 physical M-Bus slave devices and 3 000 BACnet objects, making it ideal for large-scale metering, energy analytics, and building management applications.

Operating as a BACnet/IP and BACnet MS/TP server, the device is fully compliant with B-AAC profiles and has been BTL certified. It is designed for high reliability in demanding automation environments. All connected M-Bus meters—thermal, electricity, water, or gas—are automatically discovered and their values exposed to BACnet clients for real-time monitoring, billing, or control.

Key Features:
• 3 000 BACnet objects  •  Up to 120 M-Bus meters
• Dual BACnet IP + MS/TP server functionality
• Ethernet 10/100 Mbps, RS-232 & RS-485 serial ports
• Galvanically isolated communication ports (1 500 VDC)
• USB Type-A (data logging) and Mini-B console access
• DIN-rail or wall mount, compact housing (90×88×56 mm)
• DIP-switch configuration of RS-485 termination & polarisation
