Fiber Optic Converter

Type:  Misc. Hardware
Description:  The PSI-MOS fiber optic converter system enables users to transmit fiber optic data for the most popular serial communication interfaces and bus systems. The PSI-MOS fiber optic converters allow complete isolation of Interbus, Profibus, Modbus, DeviceNet, CANopen, RS-232, and other RS-485 networks by converting the electrical copper-based signals to glass or polymer fiber technology.
Connectivity:  Modbus
Features:  Optional system power supply, power terminal block, and T-foot power bus coupler that mount on a DIN rail; Fiber optic line monitoring and diagnostics to increase operation reliability; Onboard diagnostics offer detailed information about the signal quality on the fiber optic path; Optical power budget is displayed via an LED bar-graph, making power metering virtually unnecessary; Diagnostics also monitor the copper and fiber optic bus lines for prohibitively long dominant bit level (18-bit). If failure occurs, each module disconnects the affected bus segment to prevent the transmission of corrupted data packages into neighboring bus segments. After the correction of the faulty condition, the affected segments are automatically reconnected.
Specifications:  22.5 mm wide, making it ideal for control cabinet and industrial applications; Modular system allows the use of a base module for point-to-point configurations for line structures and extended bus drops; Extension modules can be added to allow for flexible network configurations such as star couplers with up to 20 fiber optic ports.
