Product Description

The NTDI01 is a digital I/O termination unit for the ABB Bailey Infi 90 / Symphony Plus control architectures, including ABB Infi 90 and ABB Symphony Plus systems.

It functions as a passive field wiring termination interface for discrete signals, providing a secure connection point between field devices and I/O modules such as IMDSI (digital input) and IMDSO (digital output) modules. The NTDI01 helps protect internal DCS electronics from mechanical stress and wiring disturbances by centralizing field connections within the control cabinet.
