ABB NTDI01（6632113A1）

ABB Bailey NTDI01 Digital Input Termination Unit, part number 6632113A1, is a 16‑channel termination module that provides signal paths between field digital inputs and ABB’s SPDSI, SPDSO, and SPDSM I/O modules in the Infi 90/Symphony Plus distributed control system. The unit is a PCB‑based digital internal termination device designed to interface 16 digital input signals fromField devices to the IMDSI input family (for example IMDSI02, IMDSI12, IMDSI13, IMDSI14, IMDSI15) and related modules, enabling reliable termination and clean signal routing within the control network. The NTDI01 family documentation describes its role as the termination unit for digital inputs, consolidating field wiring to the appropriate I/O modules in the ABB Infi 90 architecture. In commercial listings, 6632113A1 is identified as the serial/part for this termination unit, and the board typically weighs around 0.4 kg. Market references also note that the unit is compatible with 120V AC power and that this particular model (NTDI01/6632113A1) has been discontinued by the manufacturer, with remaining stock appearing in secondary markets.
