INKNXMEB0200000 – M-Bus to KNX Master Gateway for 500 Points and 20 Devices

INKNXMEB0200000 – M-Bus to KNX Gateway (500 points, 20 devices)

The INKNXMEB0200000 is a powerful industrial-grade M-Bus to KNX gateway designed to seamlessly integrate energy metering systems with building automation infrastructure. Acting as an M-Bus master, this device collects data from up to 20 M-Bus-compatible meters and exposes up to 500 KNX-standardized datapoints to a KNX TP-1 network, enabling energy-efficient operation, detailed monitoring, and automatic billing scenarios.

With native support for KNX TP-1 and M-Bus electrical protocols, this gateway is ideal for smart building applications where real-time consumption data is essential. The integrated Ethernet port (10/100 Mbps) and the intuitive Intesis MAPS software simplify commissioning, diagnostics, and future expansions. Whether it’s for residential complexes, commercial buildings, or industrial installations, this gateway ensures your metering infrastructure becomes part of a responsive automation ecosystem.

Main features and benefits:

• Supports up to 500 data points and 20 individual M-Bus slave devices (e.g. water, gas, heat, electric meters)
• Real-time bidirectional communication with KNX objects for monitoring, control, or logic triggering
• Onboard data buffer to ensure continuity of readings in the event of KNX downtime
• Customizable alerts for abnormal energy use, communication loss, or device fault
• Direct DIN-rail or wall mountable design, IP20 housing for cabinet installation
• 3-year warranty with long-term firmware support and updates
