Title (EN) SPUR ISOLATION IN A FIELDBUS NETWORK
(FR) ISOLATION D'EMBRANCHEMENT DANS UN RÉSEAU DE BUS DE TERRAIN
Abstract: front page image
(EN) A method for providing galvanic isolation between an input or trunk interface (30) and multiple outputs or spur interfaces (38) for connecting field devices (14) to a trunk (20) of a two-wire (44a, 44b) process control network (10) includes connecting multiple sets of multiple spur interfaces to respective isolating elements (34). Each isolating element (34) connects a respective set of outputs or spur interfaces (38) to the trunk interface (30) and galvanically isolates (40, 42) the respective set of spur interfaces (38) from the trunk interface (30). Field devices (14) attached to different sets of spur interfaces (38) are also galvanically isolated from one another.
(FR) La présente invention concerne un procédé pour fournir une isolation galvanique entre une entrée ou une interface de circuit (30) et de multiples sorties ou des interfaces d'embranchement (38) pour connecter des dispositifs de terrain (14) à un circuit (20) d'un réseau de commande de processus (10) à deux fils (44a, 44b), consistant à connecter de multiples ensembles de multiples interfaces d'embranchement à des éléments d'isolation respectifs (34). Chaque élément isolant (34) relie un ensemble respectif de sorties ou d'interfaces d'embranchement (38) à l'interface de circuit (30) et isole galvaniquement (40, 42) l'ensemble respectif d'interfaces d'embranchement (38) à partir de l'interface de circuit (30). Des dispositifs de terrain (14) fixés à différents ensembles d'interfaces d'embranchement (38) sont également galvaniquement isolés l'un de l'autre.
