Problem: We need to track power usage on our motor for efficiency calculations and preventative maintenance schedules. Any ideas on how to accurately bring back this information to our PLC?
Solution: The PWT AC Power Transducer can do exactly what you need. The PWT accepts both voltage and current inputs and provides a 4-20mA signal proportional to watts or kilowatts for direct interface with your PLC.
Model Number Example
PWT / 120AC, 5A / 4-20MA / 3E / -120AC
