IN702MEB0200000 – industrial M-Bus, Modbus RTU/TCP & pulses to Modbus, KNX, BACnet, 20 meters

IN702MEB0200000 – industrial M-Bus, Modbus RTU/TCP and pulse input to Modbus, KNX, BACnet/IP and BACnet MS/TP gateway, up to 20 devices, 3000 signals, DIN rail, 24 VDC, UL/BTL certified.

IN702MEB0200000 is an industrial communication gateway from the Intesis 700series Metering Gateway family, designed to integrate M-Bus meters, Modbus RTU/TCP devices and pulse meters into automation systems based on Modbus, KNX and BACnet. The device supports up to 20 meters and a maximum of 3000 signals, making it ideal for medium-sized metering installations. The embedded M-Bus level converter eliminates the need for additional hardware, reducing costs and installation time. Acting as an M-Bus master and simultaneously as a server on the IP side, the gateway ensures full bidirectional data exchange and monitoring of electricity, water, gas and heat meters. Its versatility allows seamless use in both new projects and retrofit applications.

The IN702MEB0200000 gateway includes advanced diagnostic tools for fast detection of communication errors at both the individual meter level and across the bus. The auto-discovery feature automatically detects devices and imports registers, significantly reducing configuration time. Configurable polling intervals of up to 48 hours extend the lifespan of battery-powered meters, improving overall efficiency. Intesis MAPS allows project import and export, making replication of communication schemes across multiple sites straightforward. Advanced timeout settings enhance communication stability even with non-standard or demanding meters from different manufacturers.

The IN702MEB0200000 provides full flexibility on the BMS side with support for Modbus RTU/TCP, KNX TP, and both BACnet/IP and BACnet MS/TP. The late configuration feature allows protocol changes during operation, reducing inventory needs and simplifying project design. The gateway also supports 3 pulse inputs, enabling integration of additional electricity, water or heat meters. With support for up to 5 simultaneous TCP connections, the device guarantees stable communication with multiple supervisory systems. Certifications UL, BTL, CE and CB ensure compliance with industrial requirements, while RoHS and WEEE compliance guarantees environmental safety.

Its compact housing of 90 × 106 × 58 mm allows easy mounting on DIN rail EN60715 TH35 or directly on walls. The gateway operates at 24 VDC ±10% with a power consumption of 17 W. All communication ports are equipped with LED indicators for real-time diagnostics. Two DIP switch blocks allow setting of RS-485 bus parameters (termination and biasing), ensuring compatibility with Modbus RTU and BACnet MS/TP networks. A functional push button allows quick restoration of factory defaults or sending I-Am messages in BACnet networks, simplifying operation and maintenance.
