The product identified as ABB DDI01 is a H&B Freelance 2000 Digital Input Module in the HB Freelance hardware family.
Within the process-control arrangement, a digital input module receives discrete on/off states from field contacts and devices, then makes those states available to the controller for monitoring, sequencing, alarms, and interlocks. This is relevant where the installation calls for this specific component class.
HB Freelance provides the platform context for this product, while the PLC modules classification identifies its broader automation role. Exact application should follow the installed system configuration. Ratings and capacity should be verified against the exact model documentation.
