Abstract: A battery pack includes battery terminals operable to be electrically coupled to one or more batteries. The battery pack also includes a printed circuit board electrically coupled to the battery terminals. The printed circuit board is operable to receive operating power from the one or more batteries and/or provide operating power to one or more external devices. The printed circuit board could provide power to a transmitter and/or one or more sensors in a process control system. The printed circuit board could also include a transmitter or other industrial instrument. The battery pack further includes a removable carrier attached to the printed circuit board. The removable carrier is operable to be inserted into and removed from a housing in order to insert the apparatus into the housing and remove the apparatus from the housing. The housing could, for example, represent a cylindrical casing forming part of a pipe.

Abstract: A retainer secures one or more printed wiring assemblies in a processor unit. In one embodiment, the retainer has one or more protuberances that abut against a wiring assembly to secure it in place, or sit within a cutout section in the wiring assembly to secure the assembly in a serviceable position.

Abstract: A controller input/output module visual indicator and safety means including a light redirector, terminal block assembly and at least one circuit having at least one light emitting diode or like light transmission means positioned distally from terminal block assembly. Each light redirector is configured to receive light from each corresponding light transmission means on a proximate end and redirect the light information to a distal end adjacent to the terminal block assembly for viewing by the control operator. An optional shield or side barrier may optionally be coupled to the circuit to provide operator safety from the high voltage signals which may exist on each input/output module.
