Belden has now launched the Hirschmann™ OZD Profi G12 ATEX , Profibus FO repeaters certified for use in hazardous locations, zones 1, 2, 21 and 22. The optical ports are intrinsically safe and have got op-is approval. With a transfer rate of up to 12 Mbps, the repeater is available with a stainless steel or plastic housing. The optical function module, which has its own Ex approval, is also available without a housing. This enables it to be installed in the same housing as other components, so saving valuable space. The optical performance of the FO repeater can be continuously monitored using signal strength outputs which can be integrated in the process control system. As the Hirschmann™ OZD Profi G12 ATEX 1repeaters also support ring redundancy, it is now possible to implement highly available Profibus networks using ring or line topologies in potentially explosive environments such as those found in the oil and gas sectors and in some areas of the food industry.


Ring redundancy ensures that the FO repeater automatically switches over to another ring segment without measurable interruption, i.e. within 0 milliseconds, when a fault such as a fiber break is detected, thus guaranteeing continuous high network availability. The failure of the original connecting cable is also immediately reported to the process control system via potential-free relay contacts.

The FO repeaters have two optical ports and one electrical port. These are designed as Ex-e terminals, as are the connections for the error relays, measurement signals and redundant 24 Volt power supply. Bus termination and monitoring of signal quality can be activated via an integrated switch. Installation and on-site maintenance are aided by LEDs which indicate link status, data transfer activity and error situations.


The Hirschmann™ OZD Profi G12 ATEX 1 is a valuable addition to Belden's tried-and-tested OZD Profi family and is fully compatible with all other devices in the range. "The ATEX model can be used in any hazardous location up to zone 1 where a fast and reliable Profibus fibre optic repeater is required", says product manager Rolf-Dieter Sommer. "including large chemical plants, oil refineries and drilling platforms. According to the FO expert, "this repeater will also be the device of choice in food industry where there is a potential risk of dust explosions, such as mills".
