RS-485 Self-healing Ring Fiber Optic Converter

RS-485 Self-healing Ring(SHR) Fiber Optic Converter

One Channel Multi Protocol Bi-Directional Data.

The Dual Self-healing Ring RS485 Transmission series products provide an optical self-healing ring network for RS485/422 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.

Product Features
