ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005 identify three different S800 digital-I/O executions: NTDI02 input, NTDO02 output and NTHS03 high-speed input. The ordering numbers describe different signal directions and timing roles, not cosmetic variants.
01
Product Overview
ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005 identify three different S800 digital-I/O executions: NTDI02 input, NTDO02 output and NTHS03 high-speed input. The ordering numbers describe different signal directions and timing roles, not cosmetic variants.
In the installed station, ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005 must be matched to the terminal wiring and controller tag group for the selected function. Input, output and high-speed records cannot be swapped simply because their housings are similar.
Service work on ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005 begins with isolation and channel identification, followed by separate input-state, output-action or high-speed event checks according to the installed record.
ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005 cover different digital signal jobs in the S800 station.
01
Input acquisition
The NTDI02 record carries discrete field states into the controller input image.
02
Output actuation
The NTDO02 record sends the commanded output state toward the assigned field load.
03
High-speed event path
The NTHS03 record is reserved for the documented high-speed input or event path rather than an ordinary output channel.
04
Operating Characteristics
The three ABB records behave differently because their signal direction and timing role differ.
01
State versus action
An NTDI02 state is read from the field, while an NTDO02 state is driven toward the field.
02
Event timing
NTHS03 is checked against the installed event or fast-input assignment, not only a steady on/off indication.
03
Controller mapping
The controller tag, terminal group and selected ordering number must describe the same execution.

Frequently Asked Questions
01
How do I choose among ABB 3HAC058991-003, ABB 3HAC058991-004 and ABB 3HAC058991-005 for ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005?
For ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005, match the ABB 3HAC058991-003 input, ABB 3HAC058991-004 output or ABB 3HAC058991-005 high-speed input record to the installed channel function.
02
Why is ABB 3HAC058991-004 not interchangeable with ABB 3HAC058991-003 for ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005?
For ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005, aBB 3HAC058991-004 drives an output path, while ABB 3HAC058991-003 reads an input path; their terminal and controller roles differ.
03
What should be tested after ABB 3HAC058991-005 is installed for ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005?
For ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005, after installing ABB 3HAC058991-005, trigger the documented fast-input event and verify the controller timestamp or event response used by the project.
04
How should the three ABB ordering numbers appear on a service request for ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005?
For ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005, list ABB 3HAC058991-003 / ABB 3HAC058991-004 / ABB 3HAC058991-005 as separate records with their channel roles, not as one generic digital module.
05
What is the practical check for ABB 3HAC058991-004 for ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005?
For ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005, operate the assigned field load and confirm that ABB 3HAC058991-004 produces the expected controller output state and field response.
06
What should be isolated before removing ABB 3HAC058991-003 for ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005?
For ABB 3HAC058991-003 / 3HAC058991-004 / 3HAC058991-005, isolate the input circuit and verify the terminal group is safe before disconnecting ABB 3HAC058991-003.
