ABB TK851 3BSC950193R1 AC 800M Controller CEX-Bus Extension Cable

Description

The TK851 3BSC950193R1 is an extension cable that expands the AC 800M CEX-Bus beyond a single rail or baseplate. It allows communication modules like the CI854A (PROFIBUS) or CI867 (MODBUS TCP) to be mounted in optimal cabinet positions, overcoming space limitations near the CPU. With industrial-grade shielding to prevent EMI and robust, keyed connectors for reliable, vibration-proof connections, it ensures high-speed bus performance and is essential for complex System 800xA installations with dense communication networking and thermal management needs.
