ABB TK801V003 3BSC950089R1 Extension Cable

Technical Overview

The TK801V003 (3BSC950089R1) is a specialized 0.3-meter extension cable for the ABB S800 I/O system. It is designed to bridge the electrical ModuleBus between separate DIN rails, allowing for flexible cabinet layouts without breaking communication. When used in conjunction with bus outlets and inlets (TB805/TB845 and TB806/TB846), this cable maintains the integrity of the high-speed bus, enabling I/O modules to be distributed across multiple rows within a control panel.
