The TB820V2 with part number 3BSE013208R1 is an optical cluster modem designed for non-redundant communication operations within the S800 I/O system framework. It functions as a specialized interface for the reception, conversion, transmission, and regeneration of data signals across local or wide area industrial networks. The module establishes secure, fiber-optic links between distributed S800 I/O clusters and central controllers, ensuring noise-immune data transfer in harsh environments. Each unit comes packaged with a dedicated power supply connector and a TB807 Modulebus Terminator to ensure correct electrical termination of the local bus cluster.

Hardware Specifications

Engineering Notes

• System Architecture Integration: The cluster modem operates within the local Modulebus hierarchy to bridge communication between external controller racks and distributed S800 remote I/O blocks.
• Termination Requirement: Correct bus topology requires the installation of the included TB807 Modulebus Terminator at the physical end of the localized cluster segment to suppress signal reflections.
• Non-Redundant Configuration: This hardware variant is optimized strictly for simplex (non-redundant) communication lines; dual-line pathing architectures require alternative module selections.
• Broad Platform Compatibility: Fully verified for cross-generational deployment, bridging legacy Advant Fieldbus 100 systems with modern System 800xA control configurations.

Field Guidelines

• Module Assembly: Mount the unit onto its designated backplane slot within the I/O chassis, securing any mechanical lock latches to ensure solid alignment with the backplane communication rail.
• Power Connection: Use only the provided power supply connector block to land the required operational voltages, ensuring correct polarity before energizing the circuit.
• Fiber Optic Handling: Avoid sharp bends or pulling stresses on the optical patch cables connected to the modem interface, as excessive attenuation or physical breakage can degrade cyclic data exchange.
• Electrostatic Discharge Precautions: Adhere to strict industrial ESD measures, including wearing an approved grounding wrist strap, when handling the modem or installing the terminating plug.
