BUS EXTENSION END MODULE

Bus Extension End Module


The 750-627 End Module for Internal Data Bus Extension is snapped onto the DIN-rail at the end of the module assembly like the standard 750-600 End Module. The assembly is terminated with the module, to which a connecting cable can be attached with an RJ-45 connector.

Power to the internal electronics is supplied via internal data bus. One end module and at least one 750-628 Coupler Module for Internal Data Bus Extension are an operative unit. The fieldbus coupler/controller performs all diagnostic and commissioning tasks.

Number of coupler modules: up to 10; Distance (max.): 5 m (10 m see manual); (end/coupler modules or coupler/coupler modules)

Transmission medium: Shielded copper cable (ETHERNET patch cable); 4 x 2 x 0.25 mm², twisted pair, double shielding, STP (Shielded Twisted-Pair)
Supply voltage (system): 5 VDC; via data contacts
Current consumption (5 V system supply): 70mA
Isolation: 500 V system/field
