Backplane Bus and Industrial Network Interface

The ABB TB805 belongs to the ABB S800 I/O Modulebus accessory family and provides a physical connection point for extending Modulebus communication paths. Therefore, the adaptor maintains the required mechanical alignment between the controller-side interface and external TK801 extension cables.

The TB805 uses a passive signal routing structure without internal processing firmware. Consequently, it does not modify communication data or require configuration parameters. The component supports ABB industrial control architectures where I/O density scaling and backplane bus communication velocity management are handled by the active controller and I/O modules.

The D-sub 25 female interface provides a defined electrical connection point. Additionally, correct cable shielding and grounding practices help maintain signal integrity in industrial environments.

Frequently Asked Questions

Q: Does the TB805 require an external power supply?
A: No. The TB805 is a passive Modulebus extension cable adaptor and does not require external power input.

Q: What cable connects to the TB805 interface?
A: The TB805 is designed for use with the ABB TK801 Modulebus extension cable through its D-sub 25 female connector interface.

Q: Does the TB805 contain firmware or communication configuration settings?
A: No. The TB805 is a hardware adaptor without firmware functions or user-configurable parameters.

Field Installation Guidelines

Install the TB805 according to ABB S800 I/O system installation procedures. Verify that the D-sub 25 connector is fully seated and mechanically secured before system operation.

Route the TK801 extension cable separately from high-voltage power wiring and high-current switching conductors. Maintain proper cable bending radius and avoid excessive mechanical stress on the connector assembly.

Connect cable shielding according to the system grounding design. Confirm that all Modulebus extension connections are correctly installed before applying power to the associated ABB control system.
