Bailey 6632115T1 Analog Input Termination Unit

The Bailey 6632115T1 Analog Input Termination Unit is an NTAI05 termination module for ABB’s INFI90 Bailey control systems, providing field-wiring termination and basic signal conditioning for analog inputs on the INFI90 I/O network. Identified as Pt. No. 6632115T1 with an enclosure part 6632114AA1, this unit is frequently cataloged as Bailey NTAI05 6632115T1 and represents the analog input termination option within the INFI90 termination family. The unit draws power from a +24 V DC supply at up to 0.5 A and has a listed weight of about 390 g; supplier pages also note a housing designation of Face3 94 V0. Within a Bailey INFI90 installation, the NTAI05 termination unit is used to terminate and organize analog input wiring from sensors and transducers before signals enter the I/O backplane, helping preserve signal integrity and simplifying field cabling in termination panels. Designed for use in Bailey INFI90 termination panels, the 6632115T1/NTAI05 pair plugs into the INFI90 backplane alongside other analog input modules to streamline wiring, maintenance, and reliability in legacy automation environments.
