EXTERNAL COMMUNICATIONS INTERFACE FOR REVENUE METER

摘要

A revenue meter includes electronics for measuring the delivery of electrical energy from an energy supplier to a consumer through an electric circuit. An interface link connects to the revenue meter. An I/O and communications device connects the interface link to the electric circuit. The I/O and communications device uses a serial interface to communicate with the revenue meter. The I/O and communications device provides one or more of analog inputs and outputs, digital inputs and outputs, and communications ports.
