ABB S800 ModuleBus Communication Extension

The TK801V003 cable supports ABB industrial control architectures by extending the S800 ModuleBus physical connection. Furthermore, the shielded cable design maintains signal integrity during communication between connected I/O modules.

ABB S800 systems use ModuleBus communication for distributed I/O management. The cable enables installation flexibility by allowing I/O components connected to the same electrical ModuleBus network to be positioned on different DIN rails.

The extension cable uses a D-SUB 25 male-female interface and maintains the required electrical connection path for ModuleBus communication. Additionally, the cable construction supports ABB I/O density scaling by allowing expanded module placement within the same control configuration.

Frequently Asked Questions

Q: What is the primary function of the ABB TK801V003 cable?
A: The TK801V003 extends the ABB S800 ModuleBus connection between I/O module assemblies using a shielded D-SUB 25 male-female cable interface.

Q: Does the TK801V003 require an external power supply?
A: No. The TK801V003 is a passive extension cable and does not require an external power connection.

Q: Can the TK801V003 be used for separated DIN rail installations?
A: Yes. The cable supports ModuleBus extension applications where ABB S800 I/O modules require physical separation between mounting locations.

Field Installation Guidelines

• Install the cable according to ABB S800 system installation requirements and ModuleBus connection procedures.
• Verify that the D-SUB 25 male and female connectors match the corresponding ModuleBus interfaces before installation.
• Maintain proper cable routing to avoid mechanical stress, sharp bending, and interference from high-voltage power conductors.
• Connect the cable shield according to the control cabinet grounding practice to maintain electromagnetic compatibility.
• Confirm ModuleBus communication status after installation through the ABB system engineering tools.
