ABB SC560 3BSE008105R1 Submodule Carrier with Local CPU

Product Overview

The SC560 (3BSE008105R1) from ABB is a compact submodule carrier equipped with an onboard local CPU, developed for distributed architectures within the Advant Controller 450RMC and AC 400 control platforms.
It operates as an intelligent communication and expansion node, handling local processing tasks while hosting communication and I/O submodules in demanding industrial control systems.

Designed for high availability environments, the SC560 supports redundant power input, fast cyclic response, and multiple industrial fieldbus protocols, making it well suited for large and mission-critical DCS installations.

Core Functions and Architecture

The SC560 integrates a local processor directly onto the carrier backplane, allowing time-critical logic execution and data pre-processing to be performed close to the field level. This architecture reduces controller load, improves determinism, and enhances overall system resilience.

The carrier accepts a range of ABB communication and function boards, enabling flexible system scaling without redesigning the control cabinet layout.
