Applies to proximity sensors connected for operation by a two-wire connecting cable to the control input of a switching amplifier. The switching amplifier contains a d.c. source to supply the control circuit and is controlled by the variable internal resistance of the proximity sensor. These devices can be used in an explosive atmosphere if they also comply with IEC 60079-11.

S'applique aux capteurs de proximité connecté en fonctionnement par un câble de liaison à deux fils à entrée de commande d'un amplificateur de commutation. L'amplificateur de commutation comporte une source à courant continu pour alimenter le circuit de commande et est commandé par la résistance interne variable du capteur de proximité. Ces dispositifs peuvent être utilisés dans…

This part of ISO 10303 specifies the use of the integrated resources necessary for the scope and information requirements for the exchange of building element shape, property, and spatial configuration information between application systems with explicit shape representations. Building elements are those physical things of which a building is composed, such as structural elements, enclosing and…

This Recommendation | International Standard defines ACSE services for ASO-association control in an open systems interconnection environment. ACSE supports two modes of communication service: connection-mode and connectionless-mode. The ACSE connection-mode service is provided by the use of the connection-mode ACSE protocol (see ITU-T Rec. X.227 bis | ISO/IEC 15954). The ACSE connectionless-mode…

The purpose of this part of ISO/IEC 16500 is to specify normative protocols and associated dynamic system behavior, including session and connection manipulation, configuration and download, for an ISO/IEC 16500 system. The emphasis is on the significant dynamic system entities (e.g., session control, call/connection control), the behavior of these entities (e.g., information flows, entity…

This part of ISO/IEC 16500 provides a toolbox consisting of lower layer protocols and physical interfaces. Each tool is applicable at one or more of the reference points within the delivery system. The physical delivery media that have been identified for this version of ISO/IEC 16500-4 are copper pairs, coaxial cable, microwave, fiber and satellite. Removable information carrying physical media…

The ACSE supports two modes of communication: connection-mode and connectionless-mode. The ACSE service definition (see ITU-T Rec. X.217 bis | ISO/IEC 15953) includes both modes of communication. This Recommendation | International Standard only includes the connection mode of communication. This Recommendation | International Standard for the connectionless mode of communication is contained in…

La présente Norme internationale spécifie les dimensions d'interface pour l'interchangeabilité et spécifie les exigences de performance pour les raccords rapides hydrauliques de type à face plane pour usage à des pressions de 20 MPa (200 bar) à 31,5 MPa (315 bar). Les raccords conformes à la présente Norme internationale ne sont pas conçus pour être connectés ou déconnectés sous…
