Abstract
A process control device includes an interface configured to communicate with other devices in a process control system. The process control device also includes a primary power source, the primary power source configured to provide power to at least one component of the process control device, which component, if not powered, would result in disruption to the control of the process. The process control device still further includes a terminal configured to electrically couple the process control device to an auxiliary power source such that the auxiliary power source provides sufficient power to the at least one component when the auxiliary power source is connected to the terminal such that the process control device remains operable to control the process in the absence of the primary power source.
