Janitza 96-PA-RCM-EL Residual Current Monitoring Expansion Module for UMG 96-PA 5232010

The Janitza 96-PA-RCM-EL adds four-channel residual current monitoring to the UMG 96-PA power analyzer, enabling early detection of insulation faults and ground leakage in industrial and commercial electrical installations. Unlike standalone RCM devices, this internal plug-in module integrates directly with the base analyzer's display, web interface, and GridVis software for centralized configuration and data analysis.

Highlights

• Four independent residual current measurement channels
• Supports Type A and Type B residual currents (AC, pulsating DC, smooth DC)
• Wide measurement range from 1 mA to 10 A with external CTs
• True RMS measurement principle for accurate readings on distorted waveforms
• Powered directly by the UMG 96-PA base device – no separate supply needed

In daily use

Install the module into the UMG 96-PA, connect external residual current transformers, and configure thresholds via the analyzer's interface. The module continuously monitors leakage currents, providing early warning of deteriorating insulation or fault conditions, which supports predictive maintenance and increased operational safety in critical power distribution systems.
