In automated manufacturing environments, visibility into machine-level energy behavior is essential for maintaining productivity and uptime. The UR20-3EM-230V-AC is installed inside control cabinets to monitor single-phase and three-phase machines such as presses, conveyors, and packaging equipment. By continuously tracking voltage, current, and harmonic behavior, it helps engineers identify overloaded motors, phase imbalance, or unusual electrical patterns that often precede mechanical failure. Its high measurement accuracy allows maintenance teams to differentiate between electrical anomalies and process-related issues, enabling predictive maintenance strategies that reduce unplanned downtime and improve overall equipment effectiveness.
Many production facilities struggle to identify where energy is consumed and wasted across different processes. The UR20-3EM-230V-AC is deployed within distributed I/O stations to capture detailed energy consumption and power quality data at multiple points in the plant. By measuring active, reactive, and apparent power, it enables energy managers to detect inefficient loads and peak demand contributors. The ability to work with external current transformers supports monitoring of high-current feeders without interrupting operations. This granular insight supports informed decisions that improve power factor, balance loads, and reduce overall energy costs.
Electrical disturbances in modern buildings can negatively affect HVAC systems, elevators, and other critical infrastructure. The UR20-3EM-230V-AC is used in building automation panels to monitor supply and distribution circuits in real time. Its capability to analyze phase angles, voltage stability, and harmonic distortion helps facility engineers identify power quality issues caused by variable-speed drives or nonlinear loads. Early detection of these issues reduces equipment stress, prevents nuisance tripping, and improves system reliability. The compact module design allows deployment across multiple zones while maintaining consistent monitoring performance.
In process-driven industries such as water treatment, food production, and chemical processing, electrical load behavior often reflects process conditions. The UR20-3EM-230V-AC monitors pumps, mixers, and compressors by translating electrical measurements into actionable operational insights. Variations in current or reactive power can indicate mechanical wear, blockages, or process instability. High-resolution measurement ensures subtle deviations are detected early, even during fluctuating operating conditions. By correlating electrical data with process parameters, operators gain an additional diagnostic layer that improves process stability, reduces energy waste, and supports continuous improvement efforts.
