ABB S800 ModuleBus Communication Characteristics
The TK801V006 extends the electrical ModuleBus connection while maintaining communication between S800 I/O modules installed on different DIN rails. The cable uses a shielded D SUB 25 interface to transfer ModuleBus signals between terminal units.
Furthermore, ABB S800 architecture uses a dedicated backplane-style communication structure for I/O module data exchange. The TK801V006 supports ModuleBus extension requirements without adding active electronic conversion components or external communication nodes.
The cable design supports physical separation of I/O assemblies while keeping the same ModuleBus network segment. Therefore, system designers can distribute S800 I/O modules according to cabinet layout and installation requirements.
Frequently Asked Questions
Q: What is the main function of the ABB TK801V006 cable? A: The TK801V006 extends the electrical ModuleBus connection between compatible ABB S800 terminal units, allowing I/O modules to be mounted on different DIN rails.
Q: Does the TK801V006 require an external power supply? A: No. The TK801V006 is a passive shielded extension cable and does not require independent power input.
Q: Which terminal units are compatible with the TK801V006? A: The cable is designed for use with ABB TB805/TB845 and TB806/TB846 terminal units within S800 I/O installations.
Field Installation Guidelines
Install the TK801V006 between compatible ModuleBus terminal units according to ABB S800 system configuration requirements.
Verify that the D SUB 25 male and female connectors match the corresponding terminal unit interfaces before installation.
Maintain proper cable routing to avoid mechanical stress, excessive bending, and interference from high-power electrical conductors.
Connect the cable shield according to the cabinet grounding design to maintain signal integrity.
Confirm ModuleBus communication after installation through the automation system engineering tools.
Avoid installing the extension cable near strong electromagnetic interference sources without appropriate shielding measures.
