Product Description

8-port RS-485 to 2-port fiber converter


IMF208-2F is a high-performance unmanaged ring network serial to fiber MODEM designed for industrial application. It supports mutual point-to-point backups of two fiber ports or ring network redundancy of multiple devices. It provides 8 RS-485 serial ports and 2 fiber ports, and adopts wall mounting, which can meet the requirements of different scenes.


DIP switch could implement master-slave configuration of devices. Hardware adopts fanless, low power consumption, wide temperature and voltage design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It can be widely used in power distribution automation, industrial automation, transportation and telecom, etc.
