Configured for high-speed signal extension across distributed node racks in automation frameworks, the ABB TK801V006 3BSC950089R2, also cataloged as the TK801V006 Modulebus Extension Cable, provides direct physical and electrical execution by linking ModuleBus segments between separate DIN-rail mount assemblies.

Part Number Breakdown & Model Configuration

Hardware Specifications

Backplane Bus & Network Communication Parameters

The hardware utilizes backplane bus communication velocity licences to maintain deterministic packet transfers across extended ModuleBus segments. I/O density scaling capabilities allow operators to bridge multiple DIN rails without violating bus timing constraints or update intervals. Firmware flash compatibility ensures that low-level communication protocol stacks remain synchronized across distributed node architectures during high-speed process operations.

Package Contents & Ordering Info

• 1 x ABB TK801V006 Modulebus Extension Cable (Part Number: 3BSC950089R2)
• 1 x D-Sub 25 Male/Female Connector Set

Physical Installation & Grounding Guidelines

• Align the D-Sub 25 male and female connectors carefully with the corresponding ports on the bus extension modules to prevent bent pins.
• Secure the locking screws on both connector ends to maintain structural stability against continuous industrial vibration.
• Ensure the outer shielding braid maintains continuous low-impedance contact with the cabinet grounding plane to suppress noise.
• Keep the cable run physically separated from high-voltage power lines to eliminate electromagnetic interference on the communication bus.
