Product Overview
The ABB DDI01 is a high-performance digital input module designed for ABB’s Freelance 2000 distributed control system (DCS). Engineered for industrial automation, the DDI01 serves as a critical component for real-time data acquisition and process monitoring in manufacturing, energy, and infrastructure sectors. As part of ABB’s Hartmann & Braun Digimatik series, this module combines robust signal processing with modular flexibility, enabling seamless integration with legacy and modern industrial networks .
Key functionalities include 16-channel digital signal conditioning (24 VDC input) and optical isolation for enhanced noise immunity. The DDI01 supports dry contact or voltage signals, with configurable software filtering (4 ms typical) to eliminate transient noise. Its DIN rail-mountable design (105 mm width × 35 mm depth) allows easy installation in control cabinets, while the 24 VDC power supply ensures stable operation in harsh environments (-20°C to +70°C) .
In industrial automation, the DDI01 plays a pivotal role in modernizing legacy systems by enabling interoperability with newer Ethernet-based devices. For example, it can interface with ABB’s S800 I/O modules to monitor sensor states and equipment status in production lines, enhancing operational efficiency and reducing downtime. This versatility makes it an ideal solution for upgrading aging infrastructure while minimizing hardware replacement costs .
