Why Choose the ABB D11 15 40 Modbus Energy Meter?
The ABB D11 15 40 Modbus is a compact single-phase direct-connected electricity meter designed for accurate energy monitoring in residential, commercial and light industrial electrical installations. As part of the ABB D11 15 DIN rail mounted meter range, it combines four-quadrant energy measurement with integrated Modbus RTU communication in an exceptionally compact one-module format.
This electronic energy meter measures active and reactive energy in both import and export directions, making it suitable for conventional consumption monitoring as well as installations with bidirectional energy flow. Its integrated RS-485 interface with Modbus RTU allows measurement data to be incorporated into compatible building-management, automation and energy-monitoring systems.
With direct connection for currents up to 40 A and operation on 220–240 V AC single-phase systems, the D11 15 40 Modbus requires no external current transformer for normal metering applications within its rating. One digital input and one digital output provide additional flexibility, while the meter occupies only one DIN module in the distribution board.

Compact Modbus Energy Monitoring
Direct-connected meters such as the ABB D11 15 40 Modbus measure electrical current without requiring external current transformers for loads within their rated range. This simplifies wiring and installation while providing accurate measurement of both consumed and exported active and reactive energy in single-phase electrical systems.
Integrated Modbus RTU communication makes the D11 15 40 Modbus particularly useful for connected energy-management applications. Measurement information can be transferred over an RS-485 network to compatible controllers, gateways and monitoring systems, allowing electricity usage to be incorporated into wider building-management and industrial automation platforms.
Typical Applications
- Single-phase residential energy monitoring.
- Commercial building sub-metering.
- Light industrial electrical distribution systems.
- Electrical control panels and distribution boards.
- Building-management and energy-management systems.
- Bidirectional import and export energy monitoring.
- Remote meter reading through Modbus RTU networks.
