Accurate Energy Monitoring for Industrial Automation and Electrical Distribution
Monitoring electricity consumption is an important part of maintaining efficient industrial equipment and electrical installations. The Finder 7M.24.8.230.0001 enables engineers to measure accumulated active energy consumption in kilowatt-hours (kWh), helping establish how much electrical energy is used by individual single-phase circuits, machinery systems and distribution loads.
The meter uses a direct-connected measurement arrangement with a 5 A reference current and a 40 A maximum current. Its Class B active energy accuracy, specified according to EN 50470-3, supports reliable consumption measurement when installed and operated within the manufacturer's stated limits.
For installations requiring centralised monitoring, the integrated S0 pulse output provides 1,000 pulses per kilowatt-hour. This enables compatible PLCs, pulse counters, building management systems and energy monitoring devices to collect consumption data remotely. The output is optically isolated and designed in accordance with EN 62053-31.
The backlit LCD display allows local inspection of accumulated energy consumption without requiring external monitoring equipment. Its compact 17.5 mm width and standard DIN rail mounting make it particularly useful in distribution boards and automation panels where space is limited.
For electrical contractors and panel builders, the sealable tamper-resistant terminal shield provides additional protection against unauthorised access to the meter connections. The device is designed for installation inside an appropriately protected electrical enclosure, with IP50 housing protection and IP20 terminal protection.
The Finder 7M.24.8.230.0001 is particularly suitable for straightforward kWh monitoring and S0 pulse-based data collection. Applications requiring additional multifunction measurements, alternative communication protocols or certified billing functionality should be assessed against the appropriate Finder 7M variant.
