Electronic wire bridge with safety circuit

摘要

An electronic bridge system includes a first interface to couple to an electrical or electro-mechanical installation to receive system information from the installation, and a second interface to couple to a second component of the installation, wherein the second component is to be bypassed or interrupted by the bridge system. Further, the system includes a bridge circuit coupled to the second interface and having a control port, and a safety circuit coupled to the first interface and having an output coupled to the control port. The bridge circuit is configured to cause bypassing or interrupting the second component upon activation, and the safety circuit is configured to output one of an enable signal and a disable signal as a function of the system information, wherein the enable signal activates the bridge circuit.

1. An electronic bridge system, comprising:
a first interface to couple to an electrical or electro-mechanical installation to receive system information from the installation; a second interface to couple to a second component of the installation, wherein the second component is to be bypassed or interrupted by the bridge system; a bridge circuit coupled to the second interface and having a control port, the bridge circuit configured to cause bypassing or interrupting the second component upon activation; a safety circuit coupled to the first interface and having an output coupled to the control port, the safety circuit configured to output one of an enable signal and a disable signal as a function of the system information, wherein the enable signal activates the bridge circuit; and wherein the bridge circuit includes a selector switch and a relay having a coil part, a first switch and a second switch, wherein the second switch is connected in series to terminals of the second interface when the selector switch is in a position “on,” and configured to close a path between the terminals, wherein the first switch is connected to the control port to close a path to the coil part of the relay, and wherein the selector switch is arranged to be parallel to the first switch when the selector switch is in a position “activate”.
