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.
