Configured for high-speed signal transmission in S800 I/O distributed control network platforms, the ABB TB810 (3BSE008560R1 Modulebus Optical Port) provides direct physical electrical execution for fiber optic-based communication between controller and I/O clusters.

Model Identification and Matrix

• Base Model: TB810
• Part Number: 3BSE008560R1
• Communication Type: Fiber Optic ModuleBus
• Series: S800 I/O

Hardware Specifications

Backplane Communication and System Integration

The TB810 facilitates I/O density scaling by bridging the local Modulebus to remote segments via optical fiber. This interface supports deterministic network behavior required for high-speed process control. The module is engineered to maintain backplane bus communication velocity across expanded distances, ensuring synchronization across up to 128 connected I/O nodes. Firmware flash compatibility is managed via the host controller, ensuring persistent communication alignment within the control topology.

Installation and Optical Link Guidelines

• Physical Mounting:
  • Align the port module with the dedicated Modulebus interface on the S800 hardware carrier.
  • Ensure the optical transceivers are clean and free of debris prior to cable insertion.
• Optical Link Standards:
  • Select fiber optic cable type based on the 10 Mbps requirement; Hard Clad Silica (HCS) is mandatory for this data rate.
  • Adhere to minimum bend radius specifications for the chosen fiber medium to prevent signal attenuation.
  • Do not exceed the 2 km maximum distance threshold to ensure signal integrity and receiver sensitivity levels.

Frequently Asked Questions

• Q: Can the TB810 be used with Plastic Optical Fiber (POF)?

  A: POF cables are restricted to systems operating at 5 Mbps; for the 10 Mbps performance of the TB810, HCS or appropriate single-mode cabling is required.

• Q: Does the port provide galvanic isolation?

  A: Yes, the fiber optic medium inherently provides total galvanic isolation between the controller and the I/O cluster, eliminating ground loop risks.

• Q: Is the TB810 hot-swappable?

  A: Hot-swapping is restricted; isolate the 24 VDC power supply before installing or removing the optical port from the Modulebus interface.

• Q: What is the maximum number of I/O modules supported?

  A: The interface is capable of supporting up to 128 S800 I/O modules when configured within the system controller's addressing limits.

• Q: How does the TB810 react to electromagnetic noise?

  A: Due to the nature of fiber optics, the unit is immune to electromagnetic (EMI) and radio frequency (RFI) interference, ensuring data integrity in high-noise environments.

• Q: Are the optical ports orientation-sensitive?

  A: Yes, maintain correct polarity (transmit to receive) when connecting fiber optic cables between the master and remote ports.

• Q: Does the TB810 require specialized configuration software?

  A: System-level configuration is managed through the controller software; the port itself is a physical layer device requiring no independent firmware setup.

• Q: What voltage source is required for operation?

  A: The device operates on standard 24 VDC supplied via the S800 I/O backplane or external auxiliary power terminal.
