ABB Bailey Signal Termination

The NTDI21-A is identified as a terminal board for ABB Bailey Infi 90 and Net 90 systems. Its primary hardware function is to provide an organized termination point between field wiring and the associated control-system interface.

The multi-channel termination arrangement consolidates field conductors at the terminal-board level. Installation should maintain the intended channel identification and wiring segregation of the connected control-system cabinet. No independent communication protocol, processor function, or signal-conditioning specification is provided in the supplied data.

Frequently Asked Questions

Q: What systems are specified as compatible with the NTDI21-A?

A: The supplied information specifies ABB Bailey Infi 90 and ABB Bailey Net 90 systems.

Q: What type of signal termination is specified?

A: The supplied data identifies multi-channel digital input termination, typically described as a 16-channel arrangement.

Q: Can the NTDI21-A be installed on a DIN rail?

A: Yes. The supplied mounting information lists cabinet, mounting rack, and DIN-rail installation.

Field Installation Guidelines

Install the terminal board on the specified cabinet, mounting rack, or DIN rail with adequate mechanical support. Route field conductors according to the cabinet wiring design and maintain clear channel identification from the field termination point to the associated control-system interface.

Keep signal wiring separated from high-voltage power conductors where required by the cabinet design. Cable shields, drain wires, and protective earth connections should follow the grounding scheme specified for the complete ABB control-system installation. Do not infer a separate grounding or shielding terminal arrangement unless documented for the installed configuration.

Verify terminal assignments and conductor polarity against the applicable Infi 90 or Net 90 system documentation before energizing or commissioning the connected circuits.
