Description
Product Overview
The ABB TK851 is a dedicated PROFIBUS DP communication module for the AC 800M controller family, serving as a high-performance gateway to one of the world’s most widely deployed industrial fieldbus networks. This module enables the ABB controller to function as a PROFIBUS DP-V1 Master, allowing for deterministic, high-speed integration of a vast ecosystem of remote I/O, drives, sensors, and actuators from ABB and other manufacturers. The ABB TK851 handles both cyclic process data exchange and acyclic services for parameterization and advanced diagnostics. Engineered for reliability, it features galvanic isolation and robust diagnostic LEDs to ensure network integrity. As a focused and optimized solution, it is a critical component for expanding the reach and capability of the System 800xA DCS into areas dominated by PROFIBUS technology, facilitating seamless multi-vendor automation in demanding industrial settings.
