ABB DI840 Digital Input Module | 3BSE020836R1
Overview
The ABB DI840 is a 16-channel 24 V DC digital input module engineered for the ABB S800 I/O system, part of the 800xA distributed control platform.
It is designed for both single and redundant configurations, delivering reliable and precise signal processing in complex automation environments.
Each input channel integrates current limiting, EMC protection, LED state indication, and optical isolation for robust performance.
The Sequence of Events (SOE) functionality records digital events with 1 ms resolution, ensuring accurate event tracking and time stamping.
Moreover, it includes supervised and current-limited transducer power with one output per two channels, enhancing field device protection and diagnostics.
This module is ideal for applications demanding high reliability, fast response, and efficient event monitoring in industrial automation systems.
