Product Description

ABB S800 I/O Modules AO845A Overview

The ABB S800 I/O system is a comprehensive, distributed process I/O solution that communicates with controllers via direct connection or industry-standard field buses. This open connectivity platform supports a wide range of process controllers from ABB and other manufacturers, delivering the reliability expected from a world leader in process automation.

Key System Benefits

Comprehensive: Cost-effective solutions for all field-device interfacing needs including analog/digital I/O, intrinsic-safety, and high-integrity solutions
Flexible: Highly modular design with multiple interconnection and installation options
Compatible: Supports PROFIBUS DP and ABB's Advant Fieldbus 100 for integration with non-ABB controllers
Easy Configuration: Transparent configuration as part of parent controllers without additional expertise
Reliable: Comprehensive diagnostics, hot-swapping capability, and redundancy solutions for maximum uptime
