More Information

Overview Manuals Specifications Routing SPFEC Wiring

Features:

  • Termination and routing for 15 analog field signals
  • Documented signal path to the SPFEC analog input module
  • Cabinet boundary for orderly analog loop wiring
NTAI05 concentrates fifteen analog field connections at the termination layer of the Symphony Plus cabinet.

SPFEC performs the associated analog input processing, while this unit maintains the physical signal route.

Accurate terminal and cable records are the main controls against swapped or lost loops during replacement.

Availability of NTAI05 is subject to Apter Power's current inventory and sourcing confirmation.

Analog termination path

  • Field terminals: reconcile all 15 loop identifiers.
  • Module cable: trace the connection to the SPFEC module.
  • Shielding: preserve the documented grounding arrangement.
  • Continuity: prove every conductor before loop release.

Module relationship

  • Processing role: SPFEC performs the analog input function.
  • Termination role: keep NTAI05 responsibilities separate.
  • Cable identity: retain both-end tags and connector information.
  • Point database: align field terminals with controller channels.

Replacement workflow

  • Isolation: follow the approved loop-power procedure.
  • Photographic record: capture terminal positions before removal.
  • Loop check: test polarity, continuity, and channel identity.
  • Handover: update drawings for any corrected wiring.
Description
NTAI05 is an ABB analog input termination unit that establishes the cabinet signal path for fifteen field inputs. ABB identifies the associated processing module as SPFEC.

Because NTAI05 is the wiring interface rather than the analog converter, its value lies in orderly field termination and correct routing to the SPFEC module. The terminal schedule and cable identity therefore define the practical compatibility boundary.

When preparing an NTAI05 replacement, label all field conductors, record the fifteen point assignments, and confirm the connected SPFEC path. Continuity and channel identification should be proven before analog loops are returned to the controller.

Technical notes
NTAI05 provides termination for 15 analog field inputs and ABB identifies SPFEC as the associated analog input module. Before conductor transfer, preserve the terminal map, cable identity, shield and grounding arrangement, loop-power design, and controller point list; the termination unit must not be mistaken for the signal-conversion module.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How many field signals are routed through NTAI05?
ABB describes a termination path for fifteen analog input signals between the field and the associated input module.
Which processing module should be matched with NTAI05?
The ABB Symphony Plus product catalog identifies SPFEC as the associated analog input module.
What should be labeled before replacing NTAI05?
Label every conductor, shield, cable connector, loop number, and destination so the fifteen signal paths can be reconstructed accurately.
Why is NTAI05 not an analog conversion module?
Its documented role is termination and routing; signal processing belongs to the connected SPFEC analog input module.
How should an NTAI05 loop be accepted after rewiring?
Check polarity, continuity, grounding, channel identity, and the controller reading with an approved field or simulated signal.
What purchasing details help avoid an incorrect NTAI05 supply?
Provide the connected SPFEC module, cable arrangement, cabinet application, quantity, required condition, destination, and shutdown schedule.
What common fault can follow an NTAI05 terminal transfer?
Swapped conductors, changed shield grounding, lost loop power, or a mismatched cable can produce wrong, noisy, or missing analog values.
