Press Release Summary:
Featuring 2 optical and 1 electrical port, OZD Profi G12 ATEX 1 supports HIPER-Ring redundancy, which ensures repeater switches over to another ring segment without measurable interruption in case of faults. Optical power can also be monitored continuously by signal strength outputs, which can be integrated in process control system. Stainless steel and plastic housings with or without viewing window are available for installation in explosion protection Zone 1.
Original Press Release:
New FO Repeater OZD Profi G12 ATEX 1 from Hirschmann
Highly available Profibus networks in Ex-Zone 1
The Hirschmann Automation and Control GmbH, Neckartenzlingen, is presenting the new Profibus FO repeater OZD Profi G12 ATEX 1 at the Hanover Fair. This repeater, which has a transfer rate of up to 12 Mbit/s, supports the HIPER-Ring redundancy technique. The optical power can also be monitored continuously by signal strength outputs which can be integrated in the process control system. Fast and highly available Profibus networks can therefore be extended easily to explosion protection zone 1. The ATEX approvals for zones 1, 21, 2 and 22 have been applied for.
The HIPER-Ring technique ensures that the FO repeater automatically switches over to another ring segment without a measurable interruption, i.e. within 0 milliseconds, in the case of faults such as a fibre break, thus guaranteeing a constantly high network availability. The failure of the original connecting cable is reported immediately to the process control system via potential-free relay contacts. All connections are designed as EEX-e terminals.
The repeater has two optical and one electrical port and a redundant 24 Volt power supply. A stainless steel housing or a plastic housing with or without viewing window are available for installation in explosion protection zone 1. If the repeater is to be installed with other devices in a common housing, the optical function module is also available without a housing with its own approval.
Since the OZD Profi G12 ATEX 1 offers the same functions as the other devices in the OZD-Profi product series, this device is fully compatible with the standard components for zone 2.
