ABB TB820V2 3BSE013208R1 S800 I/O Modulebus Optical Port

Product Overview

The ABB TB820V2 (3BSE013208R1) functions as the primary optical interface for S800 I/O clusters. This Modulebus Slave unit extends the reach of a controller's I/O station by converting electrical Modulebus signals into optical signals for long-distance transmission. It enables the connection of remote I/O clusters to the central processing unit without electromagnetic interference risks. We supply this unit as 100% Brand New and Original, ensuring your communication backbone utilizes current factory-spec hardware for maximum data integrity.

Engineering Advantages

• Immunity to Electromagnetic Interference (EMI): The TB820V2 utilizes optical fiber for data transmission. This medium completely eliminates the risk of ground loops and signal corruption caused by high-voltage equipment, variable frequency drives (VFDs), or heavy industrial machinery near the communication path.

• Extended Cluster Distance: Unlike standard electrical Modulebus connections which suffer from severe distance limitations, the optical link on the TB820V2 allows for the distribution of I/O clusters across significantly larger physical plant areas.

• Low Power Footprint: The module draws only 100 mA at 24V DC. This low consumption reduces the total load on the cluster power supply, allowing more power for the actual I/O modules and field-side instruments.

• High-Speed Data Synchronization: The TB820V2 maintains the high-speed timing required by the S800 I/O system. It ensures the controller receives input data and executes output commands with the same precision as a locally mounted electrical cluster.

• Stable DIN Rail Integration: The module locks securely onto standard DIN rails within the S800 I/O station framework. Its mechanical design ensures consistent contact with the Modulebus backplane, preventing communication dropouts in high-vibration environments.

FAQs

• What is the difference between the TB820V2 and previous versions like TB820?

  The TB820V2 represents a hardware revision designed for improved component longevity and compatibility with modern S800 I/O production standards. While it maintains the same core functionality, the V2 version ensures access to current factory support and warranties.

• Does this module support Hot Swap during operation?

  No. You must de-energize the I/O cluster before removing or installing the TB820V2. Attempting a hot swap can disrupt the Modulebus communication for the entire station and may cause the controller to enter a fault state.

• Can I use the TB820V2 with AC 800M High Integrity (Safety) controllers?

  No. According to the technical specifications, the TB820V2 does not support High Integrity (HI) controller configurations. For safety-critical SIL applications, you must utilize the specific communication interfaces approved for the HI series.

• How do I connect the optical cables to the TB820V2?

  The module features dedicated optical ports for transmit and receive fibers. Ensure you use the correct fiber type (typically plastic or glass depending on the distance) and verify that the connectors are clean and fully seated to maintain signal strength.
