The MooreHawke Route-Master fieldbus system has a new ATEX approval (FM pending) as a redundant intrinsically safe fieldbus system permitting the connection of any mix of FISCO and Entity devices.
A Route-Master system consists of up to eight trunk isolator modules in a 19-inch rack, each connected to one or more RM100 fieldbus device couplers. This combination is now approved suitable for any mix of FISCO and Entity field devices. The RM100 rack incorporates hot-swappable and load-sharing redundant DC power cards and full galvanic isolation. Intrinsically safe approvals extend to IEC Gas Group IIC (NEC Groups A and B), with up to 350 m per segment.
The duplex FISCO Route-Master gives a calculated MTBF of 468 years, and also allows the full FOUNDATION Fieldbus network length of 1900 m with 120 m spurs.
RM100 device couplers have auto-resetting short-circuit protection, automatic segment termination to eliminate common installation errors and commissioning delays, and LED status indicators. MooreHawke’s short-circuit protection method prevents segment failure caused by multiple device faults. A ‘fold-back’ technique automatically removes fault loads from the segment and does not permit any current flow to those devices until faults are corrected. Manual termination is also offered at the user’s request.
