HONEYWELL BUILDING MANAGEMENT SYSTEM GREEN CLASS METERS

FEATURES

Cost‑effective energy benchmarking
The Green Class line is designed to provide a lower‑cost solution to monitor energy usage trends and estimate CO₂ emissions, helping facilities manage sustainability metrics.
Sub‑metering focused
These meters allow tracking of individual loads, departments or sub‑panels for cost allocation and energy management rather than full high‑accuracy revenue metering.
Suits building energy management systems (BEMS)
They integrate into building automation and provide interval data capable of supporting benchmarking, demand analysis and energy‑saving strategies.

SPECIFICATIONS

Sensor Availability: Split-core sensors standard; optional solid-core (100 & 200 A)
Enclosure Types: Green JIC steel (indoor); optional gray NEMA 4X (indoor/outdoor); MMU configuration possible
Accuracy: ANSI C12.20, ±0.2% (1%–100% load)
Memory: Non-volatile (retains data during power loss)
Pulse Output: Fixed-value dry contact
Sensor Distance: Supports up to 2,000 ft remote sensor placement
Model Configurations: Available in multiple amp ratings (100 A – 3,200 A) and voltage systems (e.g., 120/208 V, 277/480 V, 347/600 V)

HONEYWELL BUILDING MANAGEMENT SYSTEM SMART METERS

FEATURES

Advanced communications
Smart Meters provide two‑way communication capabilities (e.g., via RS‑485, Ethernet or mesh networks) enabling remote reading, diagnostics and integration into AMI/EMS systems.
Real‑time consumption insights
These meters allow users (and facility managers) to view near‑real‑time data on power usage, enabling better decision‑making on energy consumption and cost.
Support for renewable/interactive energy systems
Smart meters help monitor bi‑directional flows (in case of solar/EV export) and support grid‑modernisation efforts.
