Finder 7M.24.8.230.0110 – 7M Series Energy meters

Why Choose the Finder 7M.24.8.230.0110 Single-Phase Smart Energy Meter with NFC?

The Finder 7M.24.8.230.0110 is a compact, MID-certified single-phase bidirectional smart energy meter designed for accurate electricity consumption monitoring, energy export measurement and convenient smartphone-based configuration. Part of the Finder 7M Series, this multifunction digital electricity meter combines a backlit LCD display, NFC technology, an infrared communication port and an S0 pulse output in a space-saving 17.5 mm DIN rail housing.

Designed for 230 V AC single-phase electrical installations, the Finder 7M.24.8.230.0110 supports direct-connected energy measurement up to 40 A, with a reference current of 5 A. Its bidirectional measurement capability allows users to monitor both imported and exported electrical energy, making it particularly useful for photovoltaic installations, commercial submetering, industrial energy monitoring and building energy management.

A major advantage of this model is its integrated NFC functionality, which allows compatible smartphones running the Finder Toolbox NFC app to configure meter settings, customise displayed information and retrieve stored energy readings. The NFC interface can also be used to read the meter's recorded energy values when the mains supply is unavailable, offering additional convenience during maintenance, inspections and power interruptions.

With Class B active energy accuracy according to EN 50470-3, MID certification, a seven-digit backlit LCD and a dedicated S0 pulse output, the Finder 7M.24.8.230.0110 provides an effective combination of certified metering, local visibility and integration with compatible external monitoring systems.

Smart Energy Monitoring with NFC and Bidirectional Measurement

The Finder 7M.24.8.230.0110 is designed to help electrical contractors, facilities managers and energy management professionals understand how electricity is consumed and transferred within a single-phase installation. Its bidirectional measurement capability distinguishes between energy imported from the supply and energy exported from the installation, making it especially useful for renewable energy systems and applications where energy flows in both directions.

The integrated NFC interface is one of the defining features of this model. Using the Finder Toolbox NFC app on a compatible smartphone, users can customise meter settings and displayed readings without relying solely on the front-panel controls. NFC also enables retrieval of stored energy measurements when mains power is unavailable, helping maintenance personnel obtain readings during shutdowns or power interruptions.

The meter's seven-digit backlit LCD display provides clear access to accumulated energy consumption and instantaneous electrical measurements. The multifunction touch button allows operators to navigate readings for voltage, current, active power, reactive power, apparent power, frequency, power factor, harmonic distortion and power flow direction. These functions make the device useful for both routine electricity monitoring and electrical performance assessment.

For integration with external systems, the S0 pulse output provides a standardised method of transmitting energy consumption information to compatible pulse counters, monitoring controllers and data logging equipment. The meter also incorporates an infrared communication port. Unlike the Finder 7M.24.8.230.0210 and 7M.24.8.230.0310 variants, this specific 0110 model does not provide an integrated wired Modbus RS485 or M-Bus terminal interface.

Installation is straightforward using a standard 35 mm DIN rail. The slim 17.5 mm housing occupies a single modular position, making it suitable for distribution boards and compact control panels. The direct-connected design supports circuits up to 40 A, avoiding the need for separate current transformers within the specified measurement range.

With MID-certified Class B active energy accuracy, the Finder 7M.24.8.230.0110 is suitable for applications requiring recognised metering performance. Installation must be completed by a qualified electrical professional, with appropriate protective devices, conductor sizing and compliance with applicable wiring regulations. Any use for commercial billing or tenant charging should also be assessed against the relevant metering and legal requirements.
