Modbus RTU Fiber Optic Converters
Model: LNK-UF1100 Series
Overview
The LNK-UF1100 series is designed for use in optical Modbus fieldbus networks. Feature with data rate up to 230.4K, 35mm DIN rail mounting, redundancy power input(9V~30VDC),relay output alarm. LNK-UF1100 contains one fiber optic transceiver and one electrical interface. The converters provide fiber optic connection in point to point, star, daisy chain topologies networks.
