  • Publication number: 20240200983
    Abstract: A metering assembly, switchboard case, adapter cradle and method of use are provided. A metering assembly of the present disclosure includes an intelligent electronic device (IED) disposed in a switchboard case. The switchboard case includes an enclosure which is connected to an electrical distribution system and a cover. The IED is mounted in a cradle which is removable from the enclosure. The cradle, or adaptor, interconnects electronics of the IED with an electrical circuit of the electrical distribution system. The cover includes a sealing mechanism which prevents removal of the cover and indicates when the cover has been tampered with. The cover further includes a sealed input/output interface which interconnects with input/output means of the IED disposed with the switchboard case. The enclosure and/or the cover have a gasket to seal the cover to the enclosure to making the switchboard case water-tight and enabled for used in outdoor applications.

  • Publication number: 20240187247
    Abstract: Apparatuses, systems, and methods for providing security in an intelligent electronic device (IED) are provided. In one aspect of the present disclosure, an IED is provided including at least one processor that receives a communication via a communication interface, the communication including an unencrypted file and a digital signature. The at least one processor decrypts the digital signature to obtain a first value, executes a hash function on the unencrypted file to obtain a second value, determines if the first value and second value match, and updates at least one firmware package stored in at least one memory of the IED with the unencrypted file if it is determined that the first value and the second value match.

  • Patent number: 8942831
    Abstract: Apparatus and methods for controlling a system that operates responsive to a plurality of input control signals are disclosed. During operation the system generates a plurality of output status/control signals. A master controller has at least first and second controllers. The first controller outputs and inputs signals over a first communication path, and the second controller outputs and inputs signals over a second communication path. The first and second controllers output signals based on input signals received over the first and second communication paths, respectively, and also based on stored control data. A plurality of input/output modules are provided. Each of the input/output modules has first and second slave controllers. The first slave controller of each of the input/output modules inputs and outputs signals over the first communication path to the first controller, and the second slave controller outputs and inputs signals over the second communication path.
