Core Technical Parameters

1. Basic Specification
   
   
   Model QA/S3.64.1, belonging to the ABB MDRC professional building automation series, is an industrial-grade energy analyzer exclusive for M-Bus (Meter Bus). Its core positioning is the core unit for centralized energy data acquisition and analysis of energy metering devices in building automation systems. A single device supports synchronous access to 16 M-Bus compatible metering devices, specially designed for the refined statistics, monitoring and management of water, electricity, gas, heat and other energy consumption in buildings. Different from ordinary metering instruments, it is a key data acquisition hub of the energy management system, balancing the multi-device access capability and the accuracy of data acquisition.
2. Core Energy Monitoring & M-Bus Communication
   
   
   Natively supports the M-Bus (Meter Bus) international standard protocol, a single device can access up to 16 M-Bus compatible energy metering devices (electric meters, water meters, gas meters, heat meters, etc.) to realize synchronous and real-time acquisition of energy consumption data of 16 devices; collect core metering parameters: cumulative energy consumption, instantaneous energy consumption, unit usage. For electrical equipment, it can additionally collect electrical parameters such as voltage, current and power; for water/gas/heat equipment, it can collect flow, cumulative usage and other parameters. The acquisition frequency is customizable to meet the refined statistical needs of building energy consumption; it supports local caching and timed upload of energy consumption data, adapting to the data interaction rhythm of different building energy management systems.
3. Compatibility & Adaptation
   
   
   Seamlessly connect to the KNX/EIB intelligent building control bus, and can upload the collected energy consumption data of 16 devices to the KNX building central control system and professional energy management platform to realize visual display, remote monitoring and report generation of energy consumption data; support the expansion of RS485/RJ45 standard industrial communication interfaces, adapting to the networking needs of building automation systems with non-KNX architecture and having strong versatility; adopt M-Bus bus standardized plug-and-play wiring, 16-channel device interfaces are uniformly designed with convenient wiring and no complex programming. Equipped with a lightweight configuration tool, non-professional operation and maintenance personnel can quickly complete device access and parameter configuration, and later maintenance only requires data troubleshooting and device communication status inspection.
4. Product Attributes
