The system-ready SGM-C4 four-line meter is a standard device for measuring active power with residential and commercial customers as a “modern measuring device.” The meter has an integrated RS-485 interface for system integration. Designed as a compact unit, it fulfils the functional requirements of the FNN industry standard. The SGM-C4 can be connected directly for both power directions (consumption and infeed) and is also available as a dual-tariff meter with external control. With the BAB adapter connected externally to the RS-485 interface, the SCM-C4 can be upgraded to a “smart measuring system.”
