这种中继器的传输速率高达12兆比特/秒，支持环形冗余技术。光功率也可以通过信号强度输出进行连续监控，信号强度输出可以集成在过程控制系统中。因此，快速且高度可用的Profibus网络可轻松扩展至防爆1区。已经申请了1区、21区、2区和22区的ATEX批准。

HIPER-Ring技术确保了在诸如光纤中断的故障情况下，FO中继器自动切换到另一个环段，而没有可测量的中断，即在0毫秒内，从而保证了持续的高网络可用性。原始连接电缆的故障通过无电位继电器触点立即报告给过程控制系统。所有连接都设计为EEX-e端子。中继器有两个光学和一个电气端口和一个冗余的24伏电源。不锈钢外壳或带或不带观察窗的塑料外壳可安装在防爆1区。

如果中继器将与其他设备一起安装在一个公共外壳中，光学功能模块也可在没有外壳的情况下使用，并获得其许可。由于OZD Profi G12 ATEX 1提供与OZD Profi产品系列中其他设备相同的功能，该设备与2区的标准组件完全兼容。

This repeater has a transmission rate of up to 12 megabits per second and supports circular redundancy technology. Optical power can also be continuously monitored via signal strength output, which can be integrated into the process control system. As a result, the fast and highly available Profibus network can be easily expanded to explosion-proof Zone 1. ATEX approvals have been applied for Zones 1, 21, 2 and 22.

HIPER-Ring technology ensures that in the event of a failure such as an optical fiber break, the FO repeater automatically switches to another ring segment without a measurable interruption, i.e., within 0 milliseconds, thus guaranteeing continuous high network availability. The failure of the original connection cable is immediately reported to the process control system via the non-potential relay contact. All connections are designed as EEX-e terminals. The repeater has two optical and one electrical ports and a redundant 24-volt power supply. Stainless steel housing or plastic housing with or without an observation window can be installed in explosion-proof Zone 1.

If the repeater will be installed in a common housing with other devices, the optical function module may also be used without the housing, with its permission. Since the OZD Profi G12 ATEX 1 offers the same functionality as other devices in the OZD Profi product range, the device is fully compatible with standard components in Zone 2.
