SCE028XD3DL1B

Alarms, Buzzers, And Sirens Overview

The SCE028XD3DL1B is an industrial-grade piezoelectric buzzer from the SCE series by Mallory Sonalert. It operates on a DC voltage range of 16 to 28V with a rated voltage of 28V and a current draw of 40 mA. The device emits a continuous tone at a frequency of 3 kHz. A key functional parameter is its integrated timing circuit, which provides a 10-second delay before activating the continuous output. This component is designed for panel mounting applications requiring reliable audio signaling in industrial environments.

Alarms, Buzzers, And Sirens Feature Summary

• Integrated internal driver circuitry enables direct connection to power sources without external components.
• Built-in timing mechanism provides a configurable 10-second delay prior to continuous signal activation.
• Piezoelectric technology ensures consistent acoustic performance across the specified operating temperature range.

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Factory automation safety alerts
• Control panel warning systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix codes against the official Mallory Sonalert datasheet to ensure correct voltage, sound level, and timing configurations. Confirm RoHS compliance requirements with the manufacturer documentation prior to ordering. Check current distribution availability as stock levels may vary by region.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a delayed continuous alert is required rather than immediate activation. Ensure the system voltage falls within the 16-28VDC range to prevent damage or malfunction. Compare the 3kHz frequency and loudness specifications against other SCE variants if different acoustic profiles are needed for the installation environment.

Alarms, Buzzers, And Sirens Part Context

This unit belongs to the SCE series of industrial audio indicators. These devices are characterized by their robust construction and internal driving electronics. The series supports various sound patterns and voltage ratings, allowing engineers to standardize on a single product family for diverse signaling needs across different equipment types.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult the official SCE Series Part Numbering guide for verified cross-references. Substitutions must match the 16-28VDC input range, 3kHz frequency, and 10-second delay feature exactly to maintain system compatibility.
