ABB 3BSE001077R1 CI540 | S100 I/O Bus Extension

Description

The ABB 3BSE001077R1 CI540 | S100 I/O Bus Extension is a dedicated communication module designed for extending S100 I/O bus systems. With compact dimensions of 23.4cm × 3.15cm × 10.8cm and a lightweight of 0.115kg, it fits seamlessly into industrial control setups without excessive space or weight load. As an I/O bus extension component, its core function is to expand the connectivity and range of S100 I/O systems, supporting enhanced modularity and scalability in industrial automation architectures. For proper operation, the module requires pairing with a bus extender such as models DSBC174, DSBC176, or DSBC173A. When connecting to S100 I/O racks, users must interface via TK575/TK580 cables, linking to the “I/O-labeled” 36-pin centerline miniature ribbon connector located on TP856. Installation of related S100 I/O components should follow official S100 I/O documentation, and note that the associated CI856 unit does not support unit redundancy. This module enables flexible expansion of I/O capabilities, making it suitable for industrial environments where extended bus coverage and reliable communication between control units and I/O devices are critical.
