ZT028LDIC3R

Overview

The ZT028LDIC3R is an industrial-grade piezoelectric alarm and indicator manufactured by Mallory Sonalert. It operates on a DC voltage range of 20 to 28 volts with a rated current of 25 mA. The device produces a continuous tone at a frequency of 3.9 kHz, achieving a sound pressure level between 85 and 95 dBA. It features integrated LED control capabilities and utilizes terminal block connections for panel mounting. The unit measures 30.7 mm in diameter and 43.44 mm in height, offering robust construction suitable for demanding industrial environments.

Feature Summary

• Integrates audible alarm functionality with visual LED indication for comprehensive status signaling
• Constructed with IP66-rated enclosure to withstand harsh industrial conditions
• Designed for secure panel mounting using terminal block electrical connections

Applications

• Industrial machinery status monitoring
• Factory automation control panels
• Heavy equipment warning systems

Procurement Notes

Verify the specific LED color configuration required for the application, as suffixes often denote optical variations. Confirm that the operating voltage aligns with the 20-28 VDC specification to ensure proper acoustic output. Ensure the installation environment meets the IP66 protection rating requirements. Cross-reference the terminal block type with existing wiring harnesses to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when both high-decibel audio alerts and visible indicators are necessary within a single housing. The 3.9 kHz frequency provides distinct audibility in noisy settings. Consider the physical dimensions of 30.7 mm diameter for panel cutout planning. The internal driver simplifies circuit design by eliminating external oscillation components, reducing overall system complexity and board space requirements.

Part Context

This part belongs to the ZT series of industrial alarms from Mallory Sonalert. The series is characterized by durable housings and high-output acoustic performance. It serves as a specialized variant combining standard alarm functions with integrated lighting elements. The product line targets sectors requiring reliable, maintenance-free signaling solutions under rigorous operational standards.

Replacement Considerations

Direct substitutes include ZT028LDIC1R and ZT028LAIC1G. Verify that alternative models match the 20-28 VDC input range and 3.9 kHz frequency. Ensure the replacement maintains the same terminal block interface and IP66 environmental sealing specifications for seamless integration.
