FINDER 7M.38.8.400.0112 Three-Phase Digital Energy Meter 80 A, Modbus RTU, MID Certified, DIN Rail

The FINDER 7M.38.8.400.0112 is a digital three-phase energy meter designed for direct connection up to 80 A. It measures active and reactive energy, voltage, current, power, power factor, frequency, and THD, with data accessible via Modbus RTU (RS485) and an S0 pulse output. Its backlit LCD and compact 4-module DIN rail housing make it suitable for sub-metering and energy management in industrial and commercial installations.

Highlights

• Direct measurement up to 80 A, no external current transformers required
• Modbus RTU (RS485) interface for integration with building management systems
• S0 pulse output (1000 imp/kWh) for remote reading or verification
• MID certified (Class B active energy) for billing applications
• Backlit LCD with 8 digits for clear reading in low light
• Compact 4-module DIN rail mounting (70 mm width)

In daily use

Install the meter on a DIN rail in a distribution board. Connect the three phases, neutral, and load conductors. The meter immediately displays total and partial energy consumption. For remote monitoring, connect the RS485 terminals to a Modbus master and poll the registers for real-time data. The S0 output can be wired to a pulse counter or building controller for demand-based control.
