Monitoring Device Manages Energy

A new high-performance, low-cost power monitoring device from Rockwell Automation accurately profiles a plant’s energy consumption and utilization data while providing manufacturers with the information needed to better control and optimize energy costs. The Allen-Bradley Powermonitor 1000 is suited for basic power monitoring applications, such as load profiling and cost allocation and has flexibility to be scaled to provide advanced capabilities, including wiring diagnostics, historical trending and advanced networking.

The Powermonitor 1000 can be applied independently as a replacement for analog meters for collecting and charting energy information, and it can be integrated into existing energy monitoring systems, including Rockwell Software RSPower, RSEnergyMetrix and RSView. The device communicates seamlessly with Rockwell Automation Allen-Bradley controllers (PLC-5, SLC, and ControlLogix families), allowing efficient sharing of energy data among a plant’s varied control systems.

The compact Powermonitor 1000 is available in five models—two transducers (TR1 and TR2) and three energy-monitors (EM1, EM2 and EM3)—with features and price points addressing a wide range of application requirements. The transducer models provide effective power factor monitoring and can measure voltage, current and power-related tags. Energy-monitor models feature the ability to measure consumption related tags such as real, reactive and apparent energy, which allows energy managers to identify where and how much energy is being used, as well as low power factor caused by inductive loads. The top line energy-monitor (EM3) provides all the features of both the transducer and energy-monitor models.
