    Up to 12 measuring current transformers can be connected to one EDS460-DG. Up to 90 EDS460-DG evaluators can be connected via a BMS bus (RS-485 interface with BMS protocol), thereby up to 1080 measuring channels (sub-circuits) can be monitored. The scanning time for all channels is approximately 4…10 s.
