AZ988-1CT-24DEC1

Relay Automotive Overview

The AZ988-1CT-24DEC1 is an automotive relay manufactured by American Zettler, designed for high-current switching applications. It features a SPDT (1 Form C) contact configuration rated for 30 A at a maximum switching voltage of 27 VDC. The coil operates on 24 VDC with a resistance of 360 Ohms and consumes 1.6 W of power. Key electrical parameters include a minimum pull-in voltage of 14.4 VDC and a maximum release voltage of 2.4 VDC. The device utilizes silver tin oxide (AgSnO) contacts and offers a mechanical life of 100,000 operations. It supports plug-in installation with quick-connect terminals.

Relay Automotive Feature Summary

• Micro-ISO form factor compatible with standard automotive blade fuse holders
• Sealed epoxy construction provides environmental protection against moisture and contaminants
• High current capacity of 30 A suitable for demanding automotive loads
• Non-latching coil design ensures reliable reset upon power interruption

Relay Automotive Applications

• Automotive lighting circuits including headlights and auxiliary lamps
• Electric motor control for fans, pumps, and wipers
• Heater and defroster system management
• General purpose high-current switching in vehicle electrical architectures

Relay Automotive Procurement Notes

Verify the specific suffix 'DEC1' to confirm the 24VDC coil specification and terminal configuration. Ensure compatibility with Micro-ISO socket types used in the target application. Check RoHS3 compliance status if required by project specifications. Confirm that the 30A rating aligns with the load requirements and thermal constraints of the circuit design.

Relay Automotive Selection Notes

Select this component when a 24VDC automotive environment requires a robust 30A switching solution. The SPDT configuration allows for common terminal usage, simplifying wiring compared to single-pole alternatives. Consider the sealed epoxy feature for harsh environments where exposure to elements is likely. Ensure the operating temperature range of -40°C to 125°C meets the ambient conditions of the installation site.

Relay Automotive Part Context

This part belongs to the AZ988 series of automotive relays from American Zettler. The series is characterized by its compact Micro-ISO size and high durability. Variants within the series differ primarily by coil voltage and contact configuration. The AZ988 series is widely adopted in global automotive manufacturing for its reliability and standardized footprint.

Relay Automotive Replacement Considerations

Direct substitutes must match the 24VDC coil voltage, 30A SPDT rating, and Micro-ISO physical dimensions. Verify terminal pinout compatibility before replacement. Generic automotive relays may lack the specific sealing or contact material properties of the original component.
