Profibus Redundant Ring Fiber Optic Converter(Modem)
Redundant Ring Profibus to Fiber Optic Converter(Modem)
The Profibus Redunant Ring Multi-Drop Self-Healing Ring Transmission series products provide an optical self-healing ring network for Profibus data interfaces over two multimode or singlemode optical fibers. The system offers maximum reliability as it can recover simultaneous faults or failures in two different locations and has contact closure outputs on each module to clearly indicate any fault location. The self-healing ring consists of two opposing data paths, ring A and ring B. Under normal operation only the primary path (ring A) is used for data transfer. If a fault is detected, the data is transferred to the secondary path (ring B) without interruption to the communications network.
The series is available in wall mount, DIN rail or 3U chassis card. Redundant Dual power supply as the option.
Product Features:
Multi mode and single mode solutions
Contact closure alarm outputs per station
Single or dual fibre configurations
Wall mount, DIN rail and 3U chassis card
