SCE028SD3DL1B

Alarms, Buzzers, And Sirens Overview

The SCE028SD3DL1B 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 current of 40mA. The device produces a soft sound level at a frequency of 2kHz. It features a 10-second delay and continuous operation mode, utilizing terminal block connections for secure mounting.

Alarms, Buzzers, And Sirens Feature Summary

• Industrial-grade construction designed for demanding environments
• Integrated internal driver circuitry for direct connection
• Configurable 10-second delay followed by continuous output
• Soft acoustic profile suitable for non-harsh alerting

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Control panel audio signaling
• Equipment fault warning systems
• Process monitoring alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix DL1B against official Mallory Sonalert documentation to confirm the 10-second delay and continuous timing parameters. Ensure the operating voltage aligns with the 16-28VDC specification. Confirm terminal block compatibility with existing wiring infrastructure before integration.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a delayed start signal is required alongside sustained audio feedback. The soft volume setting distinguishes it from louder variants in the SCE series. Verify that the 2kHz frequency meets auditory detection requirements for the target installation environment.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of industrial audio indicators. It shares the standard 40mA current draw and 28V maximum rating common to the series. The unit utilizes a piezoelectric transducer technology housed in a panel-mountable enclosure with top-mounted ports.

Alarms, Buzzers, And Sirens Replacement Considerations

SCE028LA3DL1B offers similar electrical characteristics but provides a loud sound level instead of soft. SCE028XD3DL1B delivers extra-loud output with identical delay and continuous timing functions.
