ABB REB670 Series - Page 59

binary inputs can be shared between phases by including the LDCM communication
module. This simplifies panel wiring and saves IO boards.
• This version can be used with external auxiliary 3-phase to 1-phase summation current
transformers with different turns ratio for each phase.
