ECOFAST bus cables

■
Overview
In the ECOFAST system, all devices with bus capability are
connected to PROFIBUS DP using the bus cables.
The bus cable is implemented as a hybrid cable and contains:
•
PROFIBUS DP in copper RS 485;
•
Four additional copper cores for carrying 24 V DC:
- 24 V DC, not switched (for electronics and inputs)
- 24 V DC, switched (for outputs, disconnectable e.g. for
EMERGENCY OFF)
The ECOFAST hybrid cables are sold by the meter or in fixed
lengths preassembled with ECOFAST connector (Han Brid) and
socket.
■
Benefits
•
Savings in wiring, installation, commissioning and operation
as result of standardized connection system (copper or fiber-
optic) with high degree of protection (IP65)
•
With ECOFAST, the turnaround times for offers, planning and
engineering of machines and plants can be reduced
•
ECOFAST permits fast and problem-free startup of automation
and drive systems
•
Minimization of sources of error by means of standardized
interfaces and plug connectors.
•
With ECOFAST plants remain highly available: No interruption
of power and fieldbus when replacing equipment.
