Phoenix Contact EEM-MA371 Energy Meter with Modbus TCP/IP and Rogowski Connection

The EEM-MA371 is a multifunctional energy measurement module designed for low-voltage installations up to 690 V. It features direct Rogowski coil connection and an integrated Modbus/TCP interface for accurate electricity parameter measurement in three-phase, two-phase, and single-phase configurations.

Configuration and integration are simplified through an intuitive web-based installation wizard. The device includes an LCD display with backlight, direct connections for standard Rogowski coils, and practical webserver functions for easy commissioning and service. True RMS measurement captures AC sine waveforms at 12.8 kHz / 15.4 kHz sampling, with harmonics registration up to the 63rd harmonic.

The module supports flexible network types (3PH-4W, 3PH-3W, 2PH, 1PH configurations) and offers dual communication protocols (Modbus/TCP and REST) via RJ45 Ethernet. Operating temperature range is −25 °C to 70 °C, with IP20 housing and IP40 display protection. DIN rail mounting (5 TE) with horizontal orientation.
