Core Technical Parameters

1. Basic Specification

   
   

   Model QA/S4.16.1, belonging to the ABB EQMatic professional energy analysis series, is an industrial-grade energy analysis gateway exclusively adapted for Modbus bus. Its core positioning is the centralized acquisition and data interaction core unit of Modbus metering devices for building/industrial energy management systems. A single device supports synchronous access of 16 Modbus-compatible energy metering devices (electric meters, water meters, gas meters, heat meters, industrial energy sensors, etc.), specially designed for refined monitoring, statistics, analysis and platform upload of water, electricity, gas, heat and other multi-category energy consumption in buildings/industries under Modbus protocol architecture. Different from the M-Bus models of MDRC series, it focuses on Modbus protocol adaptation, serving as a key gateway connecting Modbus metering devices to the upper energy management platform, balancing multi-device access capability with the stability and flexibility of data interaction.
   
   
2. Core Modbus Communication & Energy Acquisition & Analysis

   
   

   Natively supports Modbus RTU/Modbus TCP international standard protocols, a single device can access up to 16 Modbus-compatible energy metering devices to realize synchronous real-time acquisition and local analysis of energy consumption data of 16 devices; it can collect core metering parameters of all categories: cumulative energy consumption, instantaneous energy consumption, unit time consumption. For electrical equipment, it can additionally collect electrical parameters such as voltage, current, active/reactive power, power factor; for water/gas/heat equipment, it can collect parameters such as instantaneous flow, cumulative flow, medium temperature and pressure. The data acquisition frequency is customizable (1s~1h) to meet the refined energy consumption statistics needs of industrial/commercial scenarios; built-in basic energy consumption analysis algorithms, which can realize single device/group energy consumption statistics, year-on-year/ month-on-month analysis, support local caching of data and timed/real-time upload to EQMatic energy management platform, third-party SCADA systems, and building automation platforms.
   
   
3. Compatibility & Adaptation

   
   

   Supports multi-protocol conversion: can convert Modbus data into KNX/EIB, Ethernet TCP/IP and other protocol data, seamlessly connecting to KNX building automation systems, industrial automation systems, and professional energy management platforms; equipped with standard industrial communication interfaces (RS485, RJ45), adapting to Modbus bus networking (bus/star type), with plug-and-play standardized wiring design, 16-channel device access interfaces with unified layout and no redundant wiring; equipped with a lightweight visual configuration tool, no complex programming is required, non-professional operation and maintenance personnel can quickly complete metering device access, acquisition parameter configuration, and protocol conversion settings, and later maintenance only requires data verification and device communication status inspection.
   
   
4. Product Attributes
