Loopdrive – User and installation manual
NOTE:
Loopdrive bus (DIN rail) interconnects multiple LDB units, supplying 24V/48V DC power, common fault contact output and RS485 serial bus.
Due to current limitation single bus can supply with 24V/48V up to 32 LDB units. Larger number of LDBs should be divided and fitted onto
separate power rails. Common RS485 bus and common fault output may be shared up to the maximum number of 256 LDBs in one system
