Field replaceable electronic return for actuator

A method of providing a field replaceable electronic return for an actuator, the method comprising:

• providing a circuit board;
• mounting a backup power source on the circuit board, the backup power source configured to store backup power thereon;
• providing at least one sense circuit coupled to the backup power source, the at least one sense circuit configured to sense at least one electrical parameter of the backup power source;
• wherein the at least one sense circuit is configured to provide the at least one electrical parameter to the actuator to monitor a health status of the backup power source;
• and
• wherein the backup power source is configured to provide the backup power to the actuator upon occurrence of a power event to allow the actuator to move a controlled device from a current position to a preselected fail-safe position.

An actuator for a controlled device, comprising:

• a control board;
• a microcontroller mounted on the control board;
• and
• a field replaceable electronic return module configured to be connected to the control board and having a backup power source therein, the backup power source configured to store backup power thereon;
• wherein the field replaceable electronic return module is configured to provide the backup power to the actuator upon occurrence of a power event;
• and
• wherein the microcontroller is configured to cause the actuator to move the controlled device from a current position to a preselected fail-safe position upon occurrence of the power event using the backup power.
