2.2 Device technology QA/S 4.xx.1 Energy Analyzer, Modbus
The Energy Analyzers, Modbus RTU
QA/S 4.xx.1, are modular DIN rail
components (MDRC) in Pro M design for
installation in distribution boards on a
35 mm mounting rail.
They are compact, web-based
standalone devices for energy
management applications in Modbus
RTU networks. They log, store, display
and analyze consumption data for up to
16 or 64 electricity, gas, water or heat
meters. They automatically detect ABB A
and B series meters during
commissioning. Device access is via web
browser.
Various interfaces are available for
further processing the data.
The user interface provides graphic
analysis features such as
• A configurable dashboard
• Display and evaluation of historical
data
• Analysis of instantaneous values
• Period comparison (before/after)
• Comparison of up to 5 consumers
• Display of cost/consumption figures
by consumer groups
