ZT028LDDT8R

Overview

The ZT028LDDT8R is an industrial-grade audio indicator manufactured by Mallory Sonalert. It operates on a voltage range of 20-28VDC and features a red LED visual indicator. The device utilizes a terminal block for connection and is designed for panel mounting with a diameter of 22mm. It complies with RoHS standards and holds cUL certification, ensuring suitability for industrial environments requiring reliable audible and visual alerts.

Feature Summary

Integrated red LED for simultaneous visual indication alongside audible signaling
Industrial-grade construction suitable for demanding operational environments
Certified compliance with cUL safety standards for North American markets

Applications

Industrial machinery status monitoring
Control panel alarm systems
Factory automation equipment indicators

Procurement Notes

Verify the specific ordering suffix to confirm the exact color and voltage rating before purchase. Confirm availability status as distribution may vary by region. Ensure the panel cutout dimensions match the 22mm requirement for proper installation. Cross-reference the cUL listing number if regulatory compliance documentation is required for your specific facility audit.

Selection Notes

Select this model when a combined audible alert and red visual signal is required for DC-powered industrial panels. The 22mm form factor allows for standard mounting holes in control enclosures. Verify that the operating voltage aligns with the system's 20-28VDC supply rail. Consider the terminal block termination method for secure wiring connections in high-vibration areas.

Part Context

This component belongs to the ZT series of industrial audio indicators from Mallory Sonalert. The series is characterized by robust housing materials and standardized mounting dimensions. It serves as a direct replacement for legacy 22mm industrial alarms where dual-mode (sound and light) notification is necessary for operator awareness in noisy or visually obstructed workspaces.
