IN712MEB0500000 – industrial M-Bus to BACnet/IP & Modbus TCP gateway, 50 meters, 3000 signals

IN712MEB0500000 – industrial M-Bus to BACnet/IP and Modbus TCP gateway, up to 50 meters, 3000 signals, DIN rail, 24 VDC, BTL certified.

IN712MEB0500000 is an industrial communication gateway from the Intesis 700series Metering Gateway line, designed to integrate M-Bus meters into building automation systems based on BACnet/IP or Modbus TCP. The device supports up to 50 meters and 3000 active signals, making it suitable for large-scale metering networks in commercial, industrial, and public infrastructure. With the embedded M-Bus level converter, there is no need for additional external hardware, reducing both installation costs and complexity. Acting as a server on the IP side and a master on the M-Bus line, it enables full bidirectional integration and monitoring of water, gas, or energy meters. This universal solution significantly improves efficiency and reliability of BMS and SCADA deployments.

The gateway is equipped with advanced diagnostic features, including error detection at both the individual meter level and across the entire bus. Configurable polling intervals of up to 48 hours help extend the lifetime of battery-powered meters in low-energy applications. With the auto-discovery function, M-Bus meters and their registers can be automatically detected, which shortens commissioning time and minimizes manual configuration. Import/export functionality within Intesis MAPS allows project templates to be replicated across multiple sites with ease. Enhanced timeout settings ensure robust communication even with non-standard or demanding meters, regardless of manufacturer.

The IN712MEB0500000 provides flexible configuration of the IP-side protocol, supporting BACnet/IP or Modbus TCP, with the ability to change protocol later via late configuration. This feature allows a single hardware model to be adapted for different projects, reducing warehouse inventory and procurement complexity. Support for up to 5 simultaneous TCP connections ensures reliable integration with multiple supervisory systems. Certifications including BTL, CE, and CB guarantee compliance with international standards, while RoHS and WEEE conformity underline its environmental safety. Compact DIN rail mounting and lightweight housing make installation straightforward in electrical cabinets and control panels, ensuring practical use in professional environments.
