ABB TK851V010 3BSC950262R1 Extension Cable Assembly

Overview

The ABB TK851V010 (Part Number: 3BSC950262R1) is a specialized ModuleBus extension cable assembly designed for the S800 I/O and AC 800M automation platforms. This pre-fabricated, shielded cable is engineered to extend the local ModuleBus backbone between adjacent rows or separate DIN rail clusters of Module Termination Units (MTUs), maintaining high-integrity communication pathways across the I/O station.

Installation Notes

• Ensure the system power is completely isolated before attaching or removing the TK851V010 ModuleBus cable to protect internal active processors.
• Insert the cable connectors firmly into the designated extension ports on the starting and ending MTUs until the integrated mechanical retention clips snap into place.
• Observe the minimum bend radius requirements during routing along wire trays to avoid fracturing the internal shielded copper cores.
• Verify that the MTUs on both ends are securely grounded to the cabinet's common ground plane to optimize the cable shield's effectiveness.
