AI-390

Overview

The AI-390 is a panel-mounted piezoelectric audio indicator manufactured by PUI Audio, Inc. It operates on a 24 VDC supply and produces a continuous tone at a frequency of 2.9 kHz. The device delivers a sound pressure level of 85 dBA. Its physical diameter is 42 mm, designed for direct panel installation.

Feature Summary

Piezoelectric transducer technology for reliable audio indication
Continuous tone generation capability
Panel mounting design for secure integration

Applications

Industrial equipment status signaling
Control panel alarm indication
Electronic device audio feedback

Procurement Notes

Verify component authenticity through authorized channels as the AI-390 is listed as obsolete. Confirm availability of substitute parts such as the AI-4230-S-C24-R if current stock is unavailable. Ensure replacement components match electrical specifications including voltage and frequency requirements before procurement.

Selection Notes

Select this component for applications requiring a 24 VDC driven piezo indicator with a 2.9 kHz output. Consider the 85 dBA acoustic performance and 42 mm form factor for panel space constraints. Evaluate alternative models only if the primary part is discontinued or incompatible with existing system voltages.

Part Context

This component belongs to the PUI Audio piezoelectric indicator series. These devices are engineered for industrial and commercial audio signaling. The AI-390 specifically utilizes piezoelectric elements to convert electrical energy into audible sound waves for user notification purposes.

Replacement Considerations

The AI-4230-S-C24-R is identified as a direct substitute. Verify that the replacement matches the 24 VDC requirement and acoustic output levels to ensure functional equivalence in the target application.
