ELECTRICAL-ENERGY METER ADAPTABLE FOR OPTICAL COMMUNICATION WITH VARIOUS EXTERNAL DEVICES

摘要

An example embodiment of an electrical-energy meter comprises a sensing device for producing an electrical output proportional to an electrical current in a conductor of electrical energy, a circuit board electrically coupled to the sensing device for calculating a cumulative amount of electrical energy passing through the conductor of electrical energy, a first optical transmitter, a second optical transmitter, and an optical receiver. The first and second optical transmitters and the optical receiver are coupled to the circuit board. The first optical transmitter and the receiver facilitate optical communications between the electrical-energy meter and a first type of external device. The second optical transmitter and the receiver facilitate optical communications between the electrical-energy meter and a second type of external device.
