Fiber Optic Converter suits control cabinet applications.
Press Release Summary:
Model PSI-MOS transmits fiber optic data for serial communication interfaces and bus systems. By converting electrical copper-based signals to glass or polymer fiber technology, it allows isolation of Interbus, Profibus, Modbus, DeviceNet, CANopen, RS-232, and other RS-485 networks. Onboard diagnostics provide information about signal quality on fiber optic path. If failure occurs, each module disconnects affected bus segment to prevent transmission of corrupted data.

Fiber Optic Converter System
Harrisburg, Pa. - A new fiber optic converter system from Phoenix Contact 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.
Discrete wiring for power is no longer necessary with the optional system power supply, power terminal block, and T-foot power bus coupler that mount on a DIN rail. The PSI-MOS products also feature fiber optic line monitoring and diagnostics which increases operation reliability. The onboard diagnostics offer detailed information about the signal quality on the fiber optic path. The optical power budget is displayed via an LED bar-graph. This makes power metering virtually unnecessary.
In addition to fiber optic status, the 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.
The PSI-MOS system is only 22.5 mm wide, making it ideal for control cabinet and industrial applications. The 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.
Benefits to using fiber optic cabling in industrial applications include immunity to EMI, RFI and transient surge concerns, as well as enabling longer bus drops and creating star and tree topologies in the network system.
Phoenix Contact Inc. Quality System is registered to ISO 9001: 2000 - Quality Systems Model for Quality Assurance in design, development, production, installation and servicing.
