PS-550DG-24AQ

Overview

The PS-550DG-24AQ is an internally driven piezoelectric audio indicator manufactured by Mallory Sonalert. It operates on a DC voltage range of 6 to 28 volts and draws a current of 200 mA. The device produces a continuous tone at an oscillation frequency of 2800 Hz with a sound pressure level of 105 dB. It features wire lead termination and utilizes bracket mount installation. The physical dimensions are 54.3 mm in diameter and 41 mm in height.

Feature Summary

• Internally driven piezoelectric design for direct connection
• Bracket mount configuration for secure attachment
• Continuous tone generation capability

Applications

• Industrial machinery status indication
• Equipment fault alarms
• Process control system alerts

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm electrical characteristics and mounting style. Ensure the application voltage falls within the 6-28 VDC operating range. Confirm that the bracket mount interface matches the mechanical constraints of the target assembly before finalizing procurement.

Selection Notes

Select this component when a high-decibel, continuously sounding alarm is required for industrial environments. The internal drive circuit simplifies wiring compared to externally driven models. Consider the 200 mA current draw for power supply sizing and ensure the bracket mounting hardware is compatible with the installation surface.

Part Context

This unit belongs to the PS series of industrial audio indicators from Mallory Sonalert. These devices are designed for robust performance in demanding settings. The brand has a long history in electronic warning devices, establishing standards for panel alarms and indicators across various sectors including transportation and medical equipment.

Replacement Considerations

Cross-reference with PS-550DG-AQ or PS-551Q if similar acoustic output and mounting styles are needed. Verify that substitute parts maintain the same 6-28 VDC input range and 2800 Hz frequency to ensure consistent operational behavior in existing systems.
