Janitza UMG96RM-E 6-Channel Network Analyser with Ethernet and Residual Current Monitoring, 10-300V L-N / 18-520V L-L 5222036

The Janitza UMG96RM-E stands out as a compact yet powerful 6-channel network analyser that combines precision energy measurement with integrated residual current monitoring (RCM) and dual Ethernet/RS485 communication. Unlike basic power meters, it delivers Class 0.5S energy accuracy and full power quality analysis per IEC 61000-4-30, making it ideal for modern energy management systems where both electrical safety and data transparency are critical.

Highlights

• 6 measurement channels: 3 voltage (L-N: 10–300 V AC, L-L: 18–520 V AC) and 3 current via external current transformers (x/1A or x/5A)
• Integrated residual current monitoring (RCM) for early detection of insulation faults
• Ethernet (RJ45) and RS485 interfaces with support for Modbus TCP/IP, Modbus RTU, HTTP, FTP, NTP, SNMP, and SMTP
• Class 0.5S active energy accuracy (IEC 62053-22) and power quality measurement according to IEC 61000-4-30
• Harmonic analysis up to the 63rd order
• Clear LCD display for on-site reading and configuration
• Panel-mount design (96x96 mm) with IP54 front protection

In daily use

The UMG96RM-E is engineered for continuous monitoring in industrial and commercial installations. Its wide auxiliary voltage range (95–240 V AC / 135–340 V DC) ensures flexible integration, while the internal data logger (256 MB) stores long-term trends and events. Two digital inputs and two digital outputs allow for status monitoring and simple control tasks. The RCM function continuously measures residual currents, helping to prevent dangerous fault currents and reduce downtime. With its dual communication ports, the device can be integrated into existing SCADA or building management systems via Modbus TCP/IP or RTU, and also supports web-based access via HTTP for remote diagnostics.
