Profibus-DP to Fiber Optic Converter

View : 928
Type : Profibus to Fiber Converter
Description :

The device supports transmission of 1 channel Profibus-DP to fiber optic, with a communication speed ranging from 0 to 12 Mbps.


The device utilizes a large-scale FPGA design and incorporates proprietary technology. It supports transmission of 1 channel Profibus-DP to fiber optic, with a communication speed ranging from 0 to 12 Mbps. The device is rated IP40 for protection and features a reinforced casing made of corrugated aluminum, suitable for 35mm DIN rail installation. It accepts wide power supply inputs of both AC and DC (9~55V), offering advantages such as power redundancy and isolation protection. With a working temperature range of -40 to 75°C, it can meet the requirements of various industrial environments, providing a convenient fiber optic communication solution. Additionally, it can be optionally equipped with 1+1 fiber optic backup protection.
