RS-485(Modbus) Multi-Drop Bus Fiber Optic converter
The RS-485 Multi-Drop Bus Fiber Optic Modem series products provide an optical bus network for RS-232, RS-422 or RS-485 data interfaces over a pair of multimode or singlemode optical fibers. The Terminal module units operate as the end or terminal points and provide an electrical connection and a two fibre optical connection. The Repeater module units act as in-line repeater stations and provide a single electrical connection and two optical connections, one upstream and one downstream.
This series is available in either wall mount, DIN rail or 3U chassis card configurations.
