Product Description
Product Overview
The TU848 (Ordering Number: 3BSE042558R1) is a high-integrity Extended Module Termination Unit (MTU) specifically engineered for redundant I/O configurations within the ABB S800 I/O system. As a critical component of the System 800xA and AC 800M controller architecture, the TU848 provides the physical mounting and electrical interface for two side-by-side I/O modules. This dual-connection design allows for seamless hardware redundancy, ensuring that the process remains online even if one electronic module fails. It manages the distribution of the ModuleBus and handles automatic station addressing by shifting position signals to subsequent units in the I/O cluster.
Technical Specifications
The TU848 is designed for fault-tolerant operation in demanding industrial environments, supporting high-density signal termination.
