ABB NTDI0-A is documented for the applicable Bailey Infi 90 system configuration. Its recorded specification includes type designation NTDI0-A, product type Digital I/O termination unit. Correct selection depends on the complete article identity, installed equipment, mechanical or electrical interfaces and the documented configuration rather than appearance alone. Using the exact model helps maintenance teams avoid incompatible revisions, connector arrangements and application variants.
Before installing NTDI0-A, record the original nameplate, installed position, connected assemblies and every relevant configuration detail. Compare the supplied unit with the existing hardware and applicable ABB service documentation, isolate all affected energy sources and preserve required settings or calibration data. After installation, inspect each affected interface and complete controlled functional checks before returning the equipment to service.
The NTDI0-A ABB Digital I/O termination unit is listed as Obsolete/Discontinued by OEM. Current revision, availability and supplied scope are confirmed in the written quotation.
