Designed to bridge electrical ModuleBus segments across separate DIN-rail tiers within ABB S800 control cabinets, the ABB TK801V012 (3BSC950089R3 Modulebus Extension Shielded Cable) executes high-integrity serial signal transmission between node units.

Identification & Version Metrics

• Model Designation: TK801V012
• Material Article Code: 3BSC950089R3
• Cable Architecture: Shielded 1.2-meter ModuleBus extension link
• Platform Compatibility: ABB S800 Distributed I/O Series

Hardware Technical Parameters

System Data Exchange & Bus Behavior

• Expansion Coupling: Pairs directly with TB805, TB845, TB806, and TB846 interface units to stretch the electrical ModuleBus footprint across multi-tier panel layouts.
• Bandwidth Performance: Maintains high-speed data throughput up to 10 Mbps without causing frame corruption or timing skew across the serial path.
• Transparency: Operates as a physical layer medium, demanding no software configuration, node addressing allocation, or firmware flashing.
• Signal Shielding: Incorporates continuous metallic foil and braid coverage to suppress electromagnetic interference (EMI) originating from nearby power drives.

Shipment Configuration

• 1 x TK801V012 3BSC950089R3 Modulebus Extension Shielded Cable
• Protective factory packaging envelope

Mechanical Positioning & Routing Rules

• Bend Radius Constraints: Respect the minimum allowable bending radius of the shielded jacket during installation to prevent internal conductor breakage and impedance mismatches.
• Connector Fastening: Thread and tighten mounting screws securely onto mating D-sub or proprietary interface ports to eliminate intermittent dropouts caused by cabinet vibration.
• Grounding Path: Ensure metallic connector hoods establish 360-degree contact with the structural panel earth to preserve high-frequency noise rejection.
• Separation from Power: Route the extension cord through dedicated low-voltage wireways, keeping it physically isolated from high-voltage AC feeders and motor leads.

Technical Inquiry & Troubleshooting

• What is the total length of the TK801V012 cable assembly?

  The cable features a fixed physical length of 1.2 meters.

• Which terminal modules work alongside this specific extension line?

  It is utilized in conjunction with TB805, TB845, TB806, and TB846 expansion units.

• Can this cable span across multiple DIN rails?

  Yes, its core engineering purpose is to link I/O modules residing on separate DIN-rail tiers within the enclosure.

• What communication speed is supported across the link?

  The assembly supports data transfer speeds up to 10 Mbps.

• Does the component require external loop power?

  No, it functions entirely as a passive copper interconnect.

• What are the environmental temperature limits for running equipment?

  The cable functions reliably from -20 deg C to +70 deg C.

• What physical size and weight parameters affect freight planning?

  The unit weighs 0.3 kg and ships in a package measuring 20.3 x 5.1 x 20.3 cm.

• How should the shielding be grounded during setup?

  Connector shells must be bonded tightly to chassis ground to maintain effective noise suppression.
