3BUR001454R1 | ABB | DI814 16-Channel Isolated I/O Module

Product Description

High-Density Digital Signal Acquisition

The DI814 (Model: DI814) is a professional-grade 16-channel digital input module designed for the ABB S800 I/O platform. Engineered for high-speed signal processing in System 800xA DCS environments, the DI814 (Part Number: 3BUR001454R1) interfaces 24 V DC field signals from sensors, switches, and auxiliary contacts directly into the control logic. The module is organized into two isolated groups of eight channels each, a design choice that enhances system availability by localized fault isolation and preventing cross-group electrical interference.

Detailed Technical Specifications

The DI814 (3BUR001454R1) utilizes current-sourcing input logic and integrated optical barriers to ensure data integrity in high-EMI industrial zones.
