B&R Industrial Automation presents the X20AP energy measurement module to measure voltages, currents, frequencies and reactive components on all phases. The first step to improving energy efficiency, according to the company, is being able to measure and evaluate the amount of power actually being consumed because any deviations from normal values can be used to identify the condition of the machine, and evaluated through the use of monitoring systems such as the EnMon energy monitoring package included in B&R's APROL process control system. B&R says that its new energy measurement module also boasts:
- Current and voltage measurements up to the 31st harmonic, so the module operates at high precision, while its sensitivity and fourth channel make it suited for measuring leakage currents on the neutral line.
- The ability to preprocess signals and provide measurements together with calculated effective performance values as sets of digital variables to take some of the load off the CPU.
- Measurement value curves recorded by the module to provide the basis for optimizing traverse paths within a machine, contributing to further energy efficiency.
- Availability of 3 models for connecting 20-mA, 1-A or 5-A transformers.
