ABB 3HAC058880-002 / 3HAC058883-002 identify the NTAI05 and NTAI06 analog input executions in the ABB S800 I/O family. They perform the same broad acquisition role but remain separate ordering records with their own station and channel documentation.
In an installed S800 station, ABB 3HAC058880-002 / 3HAC058883-002 are matched to the terminal arrangement and the field-channel schedule. The selected record determines which wiring map, reference path and controller tag list must be used.
For service, ABB 3HAC058880-002 / 3HAC058883-002 are not chosen by appearance alone. The field loop is isolated, the original channel map is retained and the returned values are checked against the correct NTAI05 or NTAI06 record.
