Description
The ABB TB820-2V2 3BSE013209R1 is a high-performance Optical Cluster Modem used within the ABB S800 I/O system. It serves as a critical communication interface that allows for the expansion of I/O clusters over long distances using fiber optic links. By converting electrical signals to optical signals, the TB820-2V2 ensures interference-free data transmission in electrically noisy industrial environments, providing a bridge between the Advant Controller and remote I/O stations.

Application Fields
The TB820-2V2 is essential in distributed control architectures, particularly in:
- Large Scale Industrial Plants: Connecting I/O clusters that are physically separated by hundreds of meters.
- High-Interference Zones: Environments with high electromagnetic interference (EMI) where copper wiring is unreliable.
- Water & Wastewater Treatment: Linking remote pump stations to a centralized control room.
- Steel & Mining: Reliable communication across sprawling facilities and heavy machinery areas.
Product Usage Instructions
- Mounting: Snap the TB820-2V2 onto the DIN rail at the beginning of the I/O cluster. Ensure it is firmly seated on the ModuleBus.
- Fiber Connection: Connect the optical fibers to the TX/RX ports. Ensure the fiber ends are clean and properly polished to prevent signal loss.
- Address Setting: Configure the cluster address using the rotary switches located on the front of the module to ensure the controller identifies the station correctly.
- Power Up: The module typically receives power via the ModuleBus. Once the system is energized, check the “Run” LED to confirm the module is initialized.
- Termination: Ensure that the electrical ModuleBus is properly terminated if this module is the last or only communication interface in the local rack.
Common Questions & Answers
Q: Can I mix different types of fiber optics with this module? A: No, you should use either Plastic Optical Fiber (POF) or Hard Clad Silica (HCS) for the entire link. Mixing them can cause significant signal attenuation and communication errors.
Q: What is the difference between the TB820 and the TB820-2V2? A: The “V2” (Version 2) indicates an updated hardware revision with improved components and better compatibility with newer S800 I/O firmware, though it remains backward compatible with most legacy systems.
Q: Does this module require separate external power wiring? A: Generally, the TB820-2V2 draws its power from the ModuleBus, but it is critical to ensure the power supply module (such as a SD821/822) on that bus has sufficient capacity for all connected modules.
