Attached is a drawing that shows how to use the HOBO H22-001 Energy Logger and a Wattnode kWh Transducer to monitor bidirectional energy being used and generated by a regenerative drive AC motor (like those used on an elevator).
This same configuration of CTs, Wattnode, and pulse input adapters could also be used with the RX3000 Station to get data via the web using www.hobolink.com.
