ABB NTAI05 is an analog input termination unit for ABB Harmony Rack and Symphony Plus systems. It provides the field-wiring interface between plant transmitters and the associated analog input module.
NTAI05 routes fifteen field input signals to the SPFEC analog input module as defined in the ABB product catalog. The termination arrangement separates field wiring from the rack electronics and supports orderly maintenance of analog measurement channels.
ABB NTAI05 must be matched with the correct SPFEC module, termination cable and cabinet wiring. Verify channel assignments, signal type, shield grounding and connector orientation against the official system drawings before energizing the loop.
The NTAI05 ABB Analog Input Termination Unit is supported as an Active/Available from OEM product, subject to exact configuration and stock confirmation.
