Product Description
Product Overview
The TU860 (Part Number: 3BSE078710R1) is a specialized Module Termination Unit (MTU) designed for the Ethernet Fieldbus Communication Interface (FCI) within the ABB S800 I/O system. This high-integrity baseplate provides the essential physical and electrical interface for both single and redundant Ethernet FCI modules (such as CI871). By facilitating the connection between fieldbus adapters and the S800 I/O station, the TU860 ensures deterministic data flow and system power distribution. Its architecture is specifically optimized for mission-critical automation where network redundancy and fault tolerance are required to prevent process interruptions.
Detailed Technical Specifications
The TU860 is engineered to meet the stringent demands of System 800xA and AC 800M control environments.
