Overview
The ZT028LDIC2G is an industrial-grade audio indicator from the Mallory Sonalert ZT series. It operates on a 24 VDC nominal voltage 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 termination and panel mount installation. The unit has a diameter of 22 mm and a height of 43.44 mm. It is designed for robust industrial environments requiring clear auditory signaling.
Feature Summary
- Industrial-grade construction suitable for demanding operational environments
- Integrated LED visual indication combined with audible alarm output
- Continuous tone generation for persistent status signaling
- Terminal block connection method for secure wiring integration
Applications
- Industrial machinery fault signaling
- Control panel status indication
- Process monitoring systems
- Safety interlock verification
Procurement Notes
Verify that the specific suffix 'G' corresponds to the required color coding or variant configuration for your application. Confirm that the 24 VDC operating voltage aligns with your system power supply specifications. Ensure the terminal block interface matches your existing wiring harness or connector requirements before finalizing the order.
Selection Notes
Select this model when a high-intensity 95 dBA signal is necessary for noisy industrial settings. The 22 mm diameter offers a compact footprint compared to larger series units. Choose this part if internal driving circuitry is preferred over external drivers to simplify design. Consider the continuous tone characteristic against other pulse options available in the ZT series.
Part Context
This component belongs to the ZT series of industrial alarms and indicators by Mallory Sonalert. The series is characterized by rugged construction and versatile mounting options. The ZT028LDIC2G specifically represents a standard round form factor within this lineup, distinguished by its specific acoustic profile and electrical ratings tailored for general industrial control applications.
Replacement Considerations
The ZT028LDIC1R is a direct functional substitute within the same series, sharing identical electrical parameters and dimensions but differing in color designation.
