  • In-line passive barrier for intrinsically safe communication network
    Patent number: 7236342
    Abstract: A passive isolator may fit between two serial network cables to convert a standard serial network to a serial network suitable for use in hazardous environments.
    Type: Grant
    Filed: July 28, 2003
    Date of Patent: June 26, 2007
    Assignee: Rockwell Automation Technologies, Inc.
    Inventors: Joseph G. Vazach, Ulrich A. Behrens, Guenter Gabriel, Robert J. Kretschmann, Paraj Kayande, Robin David Slater
  • Low voltage industrial control system providing intrinsically safe operation
    Patent number: 6154683
    Abstract: Low voltage logic circuitry is used to permit an entire subsystem of an industrial controller to be placed within a hazardous environment to receive a high speed serial link and undertake the control of multiple control points without expensive and awkward long cable runs and electrically isolating circuits for each cable run. Energy and bandwidth limiting on the high speed link allows power levels commensurate with high data rates yet intrinsic safety of the media allowing it to freely pass in and out of the hazardous area. A mixture of intrinsically safe and non-intrinsically safe equipment on the same logical rack is allowed through a bus isolator providing isolated data communication in backplane fashion between modules while wholly isolating power transmission along the backplane.
    Type: Grant
