Abstract: A near field energized electronic valve actuator includes a power receiver that enables powering of control electronics using wireless RF energy received from an external device such as a laptop computer or smart cellular telephone handset when conventional power is unavailable to the actuator, thereby enabling exchange of data between the external device and the control electronics. Embodiments further enable data exchange between the control electronics and non-volatile memory during the wireless energization. The data can be exchanged, for example, during initial configuration of the actuator before customer delivery, during an unpowered maintenance period to retrieve operational log information stored by the control electronics, and/or to retrieve valve position information measured by a position sensor and/or fault-relevant data from the actuator when power has been interrupted due to an actuator or valve failure.
