Hitachi Energy advances its pioneering digital substation technology with the all-new SAM600 3.0, a process interface unit, to help transmission utilities accelerate the adoption of digital substations. The new one-box, modular SAM600 consolidates three units within a single device, enabling it to be configured as a merging unit, a switchgear control unit, or a combination of both, supporting different installation approaches.
As a merging unit, SAM600 speeds the upgrade of conventional substations to digital substations. They bridge the gap by converting analog signals and digitally distributing current and voltage information throughout the substation and to the control center. As a switchgear control unit, the device directly interfaces circuit breakers, disconnectors, and earthing switches in the field to reduce wiring to the control building by providing an IEC 61850 digital interface to operate and monitor such equipment.
