Interface device for electrical protection relay of a process conduction system and industrial installation equipped with this device

摘要

Invention Patent: B "INTERFACE DEVICE FOR ELECTRICAL PROTECTION RELAY OF A PROCESS CONDITIONING SYSTEM AND INDUSTRIAL INSTALLATION EQUIPPED WITH THIS DEVICE" D. The invention relates to a relay interface device (2) for electrical protection of an industrial installation equipped with a process conduction system, comprising operating units (3) that communicate with each other, according to a determined communication protocol (P2), through at least one network, in a split-time communication architecture for the command of the installation. It also refers to installations equipped with this device. It is equipped with material connection means (0.0 ') allowing it to be connected separately to the relays and to a service network of architectural units, it also includes logical means of conversion, allowing it to transmit, with the destination of a unit and according to the protocol (P2) explored by the units, information that was transmitted to them by the relays according to a different protocol (P1) and vice versa.
