Fiber-Optic Converters isolate DeviceNet networks.
Press Release Summary:
Modular, DIN-rail-mounted PSI-MOS-DNET system consists of fiber-optic converters that allow complete isolation of DeviceNet networks as well as full redundant operation of fiber communication lines and power supply. Immune to EMI, RFI, and transient surges, system allows use of base module for point-to-point configurations for line structures and extended bus drops. Offered with fiber-optic line monitoring and diagnostics, units display optical power budget via LED bargraph.Original Press Release:
Fiber Optic Converter System for DeviceNet
Harrisburg, PA - The new PSI-MOS-DNET modular fiber optic converter system for DeviceNet bus systems is now available from Phoenix Contact. The fiber optic converters allow complete isolation of DeviceNet networks by converting the electrical copper-based signals to glass or polymer fiber technology. There are many benefits to using fiber optic cabling in industrial applications including 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.
The PSI-MOS-DNET system is DIN-rail mounted and 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. The modular system also allows full redundant operation of both the fiber communication lines and the power supply.
The PSI-MOS-DNET 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. 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.
