More Information

Overview Manuals Specifications Hot-Switch Role Signal Paths Cable Matching

Features:

  • Sixteen field-signal paths
  • Hot-switch termination role
  • SPASO included in the documented module scope
NTDI02 provides the hot-switch termination path for 16 field signals in ABB’s HR Series architecture.

ABB connects NTDI02 with SPDSI, SPDSO, SPDSM and SPASO modules, creating a broader documented module scope than NTDI01.

Selection of NTDI02 should begin with the installed module and cable records so field wiring remains aligned during maintenance.

Availability for NTDI02 is subject to Apter Power's current inventory and sourcing confirmation.

Description
ABB NTDI02 is a hot-switch termination unit in the Symphony Plus HR Series. ABB defines the configuration around 16 field signal paths rather than as a general-purpose terminal board.

Within the I/O architecture, ABB NTDI02 routes those field paths to the SPDSI, SPDSO, SPDSM and SPASO module group. This documented scope supports maintenance of mixed digital-input, digital-output, digital-simulation and analog-output termination arrangements.

Before deploying ABB NTDI02, verify the installed module type, required hot-switch arrangement and cable family against cabinet drawings. NTDI01 data must not be substituted because ABB assigns a different module scope to that reference.

Technical notes
Before replacing NTDI02, verify the hot-switch role, the documented SPDSI, SPDSO, SPDSM and SPASO module path, all 16 field-signal assignments, and the applicable NKTU, NKST or NKSD cable. A naming similarity with another termination unit does not establish the same switching behavior or connection scope.

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.
What distinguishes NTDI02 from NTDI01 in ABB documentation?
ABB identifies this reference as the hot-switch unit and includes SPASO alongside SPDSI, SPDSO and SPDSM in its module scope.
How should the sixteen field paths on NTDI02 be controlled during a hot-switch exchange?
Map every field label to its documented module path, retain cable orientation and follow the approved switching sequence before each connection is transferred.
Which module record should be checked before installing NTDI02?
Confirm whether the cabinet uses SPDSI, SPDSO, SPDSM or SPASO and match the applicable system drawing.
Why can a cable mismatch prevent NTDI02 commissioning?
The termination path depends on the correct installed cable family, connector orientation and retained field-signal assignments.
What should technicians document before hot-switch work on NTDI02?
Record the module state, all sixteen field labels, cable part numbers, connector orientation and the approved switching procedure.
How should an NTDI02 acceptance test be organized?
Verify each documented signal path against the cabinet drawing and confirm the connected module reports the expected state after work.
