ZT028LDSP1R

Overview

The ZT028LDSP1R is an industrial-grade audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 20 to 28 VDC with a rated frequency of 3.9 kHz. The device produces a sound pressure level of 95 dBA using a fast pulse tone and draws 40 mA of current. It features a red LED integrated into the unit for visual signaling. The component utilizes terminal block connections and is designed for panel mounting. Its physical dimensions are 30.7 mm in diameter and 43.44 mm in height, providing a compact form factor suitable for industrial control panels.

Feature Summary

• Integrates audible alarm with red LED visual indicator
• Fast pulse tone generation at 3.9 kHz
• Terminal block connection method
• Panel mount installation style

Applications

• Industrial control panels
• Machine status indication
• Alarm systems requiring combined audio-visual alerts

Procurement Notes

Verify the specific suffix 'P1R' corresponds to the required red LED and fast pulse configuration. Confirm that the 20-28 VDC input range matches the system power supply. Ensure the terminal block interface is compatible with existing wiring harnesses. Check IP rating requirements against environmental conditions. Validate panel cutout dimensions against the 30.7 mm diameter specification.

Selection Notes

Select this model when both audible and visual alarms are necessary within a single housing. The 95 dBA output ensures audibility in noisy environments. The 20-28 VDC range offers flexibility for various industrial power standards. Consider the terminal block termination if screw-down connections are preferred over PCB mounting. Evaluate the fast pulse mode suitability for urgent alert scenarios compared to continuous tones.
