ABB TB811 3BSE008568R1 S800 I/O Modulebus Optical Port
Product Overview
The ABB TB811 (Part Number: 3BSE008568R1) is a high-performance Modulebus Optical Port designed specifically for the S800 I/O system. It acts as a specialized communication bridge, providing the necessary optical interface between S800 I/O modules and master controllers such as the CI810 or CI820. By utilizing fiber optic technology, the TB811 facilitates high-speed data transmission while offering superior galvanic isolation and immunity to electromagnetic interference (EMI). This module is essential for distributed control architectures where I/O stations are located at significant distances from the controller or in environments with high electrical noise, such as variable speed drive systems and power distribution centers.
