Product Details

Within the Tri-GP safety system, the Triconex AI3351S2 is an analog input module. It receives analog field measurements and presents them to the controller through the module’s triplicated input architecture, so the exact S2 hardware identity must remain intact during selection.

On the Tri-GP signal path, Triconex AI3351S2 receives an analog field measurement at its termination assembly and passes the value through a triplicated input path to the controller. Its role is therefore input-only; it does not issue a digital or analog output command.

Within the TriStation 1131 project, Triconex AI3351S2 is represented by its complete S2 model identity and its configured analog point. The chassis position, termination assembly, and field signal range must describe that same input path so the controller data point remains tied to the correct hardware.

Product Functions

Triconex AI3351S2 is selected when the system must acquire analog field values, not discrete states or commanded outputs.

Signal entry

Analog field wiring enters the AI termination path.

Controller data

The acquired value is delivered to the Tri-GP controller data image.

Module identity

The AI3351S2 suffix remains part of the configured module identity.

System Integration

Triconex AI3351S2 must be matched to the Tri-GP chassis, termination, and software record as one installation set.

Chassis position

Use the configured Tri-GP analog input position.

Termination match

The field termination assembly must match the AI module family.

Project mapping

The TriStation 1131 project must use the same complete model identity.

Product Q&A

Where does the measured signal travel in Triconex AI3351S2?

For Triconex AI3351S2, The analog field signal enters the matching termination assembly, passes through the triplicated AI path, and becomes a value in the Tri-GP controller data image. The module is therefore on the field-to-controller side.

Why is Triconex AI3351S2 more specific than the 3351 family name?

For Triconex AI3351S2, The S2 suffix is part of the complete module identity used by the hardware and software records. Omitting it loses the revision detail needed to identify the configured AI point.

What must agree at the termination and project level for Triconex AI3351S2?

For Triconex AI3351S2, The Tri-GP chassis position, analog termination assembly, field signal range, and TriStation 1131 module record all describe the same analog input path. A mismatch breaks the relationship between the physical terminal and controller point.

Can Triconex AI3351S2 issue a field command?

For Triconex AI3351S2, No. Its signal direction is field to controller and its I/O role is analog input only; it is not a digital or analog output device.

How does the triplicated path affect the data point in Triconex AI3351S2?

The analog measurement is carried through the module’s triplicated input architecture before it is presented to the controller. The project mapping still needs the complete AI3351S2 identity and point assignment.

Which records should show the complete Triconex AI3351S2 model?

Keep AI3351S2 in the chassis list, termination record, and TriStation configuration so the analog input role is not confused with the similarly numbered output families.
