摘要： A contact wetting circuit 100 is disclosed for supplying wetting current to sense the state of dry contacts of a switch SW1 setting for an electronic device 10. The contact wetting circuit includes an RC circuit 110 having a resistor R1 and a capacitor C1, and a controller 120 connected to a power supply 130 of the device. The controller supplies a first voltage to the RC circuit to produce a charging current having an average current and/or a peak current below the wetting current parameter of the dry contacts. The charging current is used to charge the capacitor C1 during the first time period. The controller stops the supply of the first voltage to the RC circuit after sufficient charging to allow the charged capacitor C1 to supply a second voltage, across the switch SW1, to produce a wetting current. Thereafter, the controller polls and senses the state of the switch SW1, and performs certain operations accordingly.

摘要： A circuit includes an evaluation node through which current flows from a voltage source node to a sensed switch when the sensed switch is closed. First and second control switches are disposed between the voltage source node and the evaluation node to switch between first and second current paths for the current. The current passes through the first control switch when flowing along the first current path. The second control switch is coupled to a control terminal of the first control switch to deactivate the first control switch and allow the current to flow through the second current path. Multiple passive circuit elements are configured to establish first and second current levels for the current. The passive circuit elements are disposed between the voltage source node and the evaluation node in a circuit arrangement in which no current path to ground is present when the sensed switch is open.

摘要： A communicating circuit breaker architecture with automatic load center position identification links circuit breakers having electronics for reporting a self-status signal including operating data and a position identifier. Each breaker has light pipes with optical ports at its sides for communicating with its neighbors and preferably a mechanically operated optical shunt providing an optical path through the breaker in the event of a trip. Each breaker has optical data transceivers for the light pipes which transmit self-status information through the light pipes and receive and repeat neighboring breaker status signals to its neighbors. The breakers form a network via their aligned optical ports reporting to an aggregator device in a known position of the Load Center which transmits breaker status reports outside the load center. Each breaker has a logic unit for determining its position in the load center based on the received position of a neighboring device.
