ZT028LDIC1R

Overview

The ZT028LDIC1R is an industrial alarm and sound indicator from the Mallory Sonalert ZT series. It operates on a 20-28 VDC supply 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 of 95 dBA. It features terminal block connections for secure wiring and offers IP66 ingress protection. The unit measures 30.74 mm in diameter and 43.44 mm in height.

Feature Summary

• Combines audible alarm signaling with visual LED indication in a single industrial-grade housing.
• Provides high-intensity acoustic output suitable for noisy factory environments.
• Features robust environmental sealing to withstand harsh industrial conditions.
• Utilizes internal drive circuitry for simplified integration into control panels.

Applications

• Industrial machinery status monitoring
• Factory safety alarm systems
• Control panel fault indication
• Heavy equipment operational alerts

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm voltage, tone type, and color specifications. Ensure the terminal block connection style matches the existing panel wiring infrastructure. Confirm that the IP66 rating meets the environmental requirements of the installation site. Cross-reference the physical dimensions with available mounting space constraints before finalizing procurement.

Selection Notes

Select this model when a combined audio and visual alert is required for critical industrial processes. The 20-28 VDC operating range suits standard DC control systems. The 95 dBA output ensures audibility in high-noise areas. Consider the terminal block interface if screw-down wiring is preferred over PCB mounting. Evaluate the IP66 rating against potential exposure to dust or water jets.

Part Context

This component belongs to the ZT series of industrial alarms, designed for durability and reliability in demanding settings. The series typically includes various configurations for different voltages and tones. The ZT028LDIC1R specifically addresses applications needing both sound and light signals. It represents a standardized solution for panel-mounted indicators in automation and manufacturing sectors.

Replacement Considerations

Check for direct substitutes within the ZT series offering identical electrical parameters. Verify compatibility with existing mounting holes and terminal block spacing. Ensure replacement units maintain the same IP66 rating and UL/cUL certification status for regulatory compliance.
