摘要： The present invention is a manufacturing system including a hazard zone and a non-hazard zone. The system includes a storage device, located in the hazard zone, for electrically storing information. The system further includes a communication device, also located in the hazard zone, for storing information to and reading information from the storage device. In the non-hazard zone, a controller is in electrical communication with the communication device. The controller controls the system based on information read from the storage device by the communication device. To limit electrical energy passing to the communication device, an intrinsic safety barrier located in the non-hazard zone is connected between the communication device and the controller device.

摘要： Bei einem modularen Feldgerät für die Automatisierungstechnik mit einem Hauptmodul, dass zur Signalerzeugung und/oder Signalverarbeitung dient und das mehrere Signalein-/bzw. Signalausgänge In1-InN bzw. Out1-OutN für interne Signale aufweist, sind diese Signalein-/bzw. Signalausgänge mit austauschbaren Modulen D1 - DN bzw. D1'-DN' verbunden, die Anschlüsse für externe Signale aufweisen. In den Modulen D1 - DN bzw. D1' - DN' sind jeweils elektrische Begrenzermittel für die externen Signale vorgesehen, die als Barrieren gemäß einer vorgegebenen Zündschutzart ausgelegt sind. Durch den modularen Aufbau erhält man ein sehr flexibles Feldgerät, das einer vorgegebenen Zündschutzart entspricht.

摘要： The invention concerns an intrinsically secure device for supplying redundant current-voltage for an electricity receiver in a zone protected against explosions. The device is of the type comprising at least two supply circuits for providing a current-voltage supply, and an intrinsically secure protective device for limiting a current-voltage supply of the power supplying the receiver in a zone protected against explosions. The inventive device is characterized in that the supply circuits are mounted mutually parallel, and the protective device includes at least a resistive current limiter ensuring intrinsic security when the supply circuits are activated in parallel.

摘要： To detect a power supply failure on an intrinsically safe field bus of a manufacturing process control system in an efficient manner there is provided a field device with a discharge protection unit which is connected to a control bus (10) for supply of an operating current from the control bus (10) to the field device (20, 22). The discharge protection unit (32) inhibits a discharge of energy stored in the field device (20, 22) to the control bus (10). The field device also comprises a controller unit (38) adapted to control the operation of the field device (20, 22) and being powered with the operating current from the control bus (10). According to the present invention the discharge protection unit (32) comprises at least two rectifying elements inserted into the current path of the operating current with identical conducting directions and an input signal or an output signal of a selected rectifying element is supplied as interrupt signal to the controller unit (38) for power supply failure detection.

摘要： Low voltage logic circuitry is used to permit an entire subsystem of an industrial controller to be placed within a hazardous environment (20) to receive a high speed serial link (28) 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 (24' and 24) on the same logical rack is allowed through a bus isolator (92) providing isolated data communication in backplane fashion between modules while wholly isolating power transmission along the backplane.
