ProfiHub A5
5 Channel Profibus DP Spur and Repeater component
is an advanced flexible and robust network component for Profibus DP installations, which makes the implementation of long multi-device spur lines and backbone structures with star/tree segments possible Profibus DP is a high-speed communication bus that has to comply with strict rules concerning spur lines, because of possible reflections that could lead to communication disturbances

If spur lines or star segments are required, costly investments in repeaters have to be done.
The ProfiHub A5 is a perfect economic solution to implement reliable spur lines in high speed DP networks.
It has the functionality of 5 galvanic isolated transparent repeaters.
This allows network structures with extended spur lines that individually can handle a maximum of 31 devices and a length equal to the main bus.
Product Features unclude 5 Galvanic isolated channels (repeater segments), transparent for all Profibus DP protocols, DP - RS 485 specifications for each channel, 9,6 Kbps to 12 Mbps (automatic detection), 31 devices per channel, 1200 m spur line length (depends on transmission speed), No limit in serial placement or cascading of ProfiHubs, no Address is required, Integrated termination facilities (switches), Configurable grounding system (direct or capacitive), and IP 65 classification (according to DIN 40 050).
Application areas include: Dynamic spur lines to actuators, flow meters and pH analyzers; Removable drives and motors; Pull/Plug motor control centers (drawers); Outdoor applications with device and cable stress; Roof mounted devices in Tank Parks; Dirty and Humid environments; Barrier for non galvanic isolated equipment; and large star/tree structured networks.
Benefits to the user include: Hot slave insertion and removal during operation, Short circuit protection on each channel, Compact and robust construction, Status and error display (per channel), Standard glands can be replaced with M12, On-board DB9 female connector for maintenance activities, Suitable for all DP cables types, Conveniently arranged networks, Easy extendable installations, and most importantly cost Savings.
The unit will be ready for shipment shortly, and can be purchased from Profibus Ireland.
