|PROFIBUS Hubs and Repeaters|
In addition to test equipment for PROFIBUS, PROFINET and AS-i networks, we also offer the versatile and useful range of Procentec PROFIBUS Hubs and Repeaters, including the A5, B5, C5 and new COMbricks.
Following initial release of their IP65 rated Procentec ProfiHub A5, 5 channel repeater for outdoor installation, Procentec repackaged the associated circuits into a smaller format for DIN rail mounting within equipment cabinets – this product, the Procentec ProfiHub B5, includes a solid earth rail for clamping of PROFIBUS cable screens, together with 9-pin D connectors for incoming and outgoing segment connection, or for monitoring of incoming and outgoing segment signals. Alternative screw terminal connectors are provided for incoming/outgoing main PROFIBUS segment connection, for each outgoing segment connection and for 10 to 32 volt DC power supply in each type of unit. Slide termination setting switches are fitted for the main and secondary segments in both the A5 and B5 units.
The ProfiHub A5 units may be supplied with optional heavy internal earth rails for clamping of cable screens. They may also be fitted with internal 110/230 volt AC mains to DC power modules : M12 connectors, instead of the standard cable glands, are also available.
For exceptionally demanding outdoor environments, Procentec also offer the ProfiHub C5 units, which include a ProfiHub B5 module, mounted within a steel waterproof enclosure with robust EMC protection.
The successful ProfiHub range has been further extended by release of the single channel Procentec B1 Repeater, allowing for dual power supplies, together with the very fast, robust PROFIBUS drive and isolation characteristics of both the ProfiHub A5 and B5 devices.
During 2011, Procentec launched COMbricks modular repeaters with embedded ProfiTrace OE (ProfiTrace-over-Ethernet) for permanent automatic network status monitoring. Each COMbricks head station can collect performance information from up to 4 separate PROFIBUS networks via local backplane, saving incident details to an SD memory card. Alarm reports may be sent by email via an Ethernet port. Both stored and real-time information can then be accessed by remote computers, using a normal browser program.
In order to ensure robust termination of PROFIBUS DP networks, we offer the Procentec T1 Active Terminator. This small DIN rail mounted module includes dual power supply connectors and associated status LED indicators. The unit includes a 9-pin D connector for test point access, allowing inspection of waveforms and signals on that segment.
We also offer Siemens PROFIBUS Repeaters, Active Terminators and other network components, in addition to a wide range of PROFIBUS and PROFINET cables and associated cable strip tools.
