AZ9731-1C-24DC2R1

Relay Automotive Overview

The AZ9731-1C-24DC2R1 is a Mini-ISO automotive relay manufactured by American Zettler. It features a 24 VDC coil and SPDT (1 Form C) contacts rated for 40 A switching current. The component utilizes quick connect terminals and is designed for high in-rush applications with vibration resistance. Dielectric strength between coil and contact is 500 Vrms. Maximum switched voltage is 75 VDC, supporting up to 560 W resistive load.

Relay Automotive Feature Summary

• SPDT contact configuration providing one normally open and one normally closed circuit
• Quick connect terminal design for rapid installation
• High momentary carry current capability exceeding nominal rating
• Epoxy sealed construction for environmental protection

Relay Automotive Applications

• Automotive electrical systems requiring 24VDC control
• Heavy-duty lighting circuits
• Motor control applications
• Power distribution modules

Relay Automotive Procurement Notes

Verify the specific suffix '2R1' against the manufacturer datasheet to confirm resistor or diode parallel configuration. Ensure the 24 VDC coil voltage matches the system supply. Confirm that the SPDT contact arrangement meets the circuit logic requirements before procurement.

Relay Automotive Selection Notes

Select this model when a 40 A switching capacity is required in a compact Mini-ISO footprint. The SPDT configuration allows for complex switching logic compared to single-pole variants. Verify compatibility with existing mounting brackets and connector types due to the quick connect terminal style.

Relay Automotive Part Context

This component belongs to the AZ9731 series of Mini-ISO automotive relays. The series offers various contact arrangements including SPST and SPDT options. Different coil voltages are available within the same form factor to suit diverse vehicle electrical architectures.

Relay Automotive Replacement Considerations

Direct substitutes include other AZ9731 series models with matching SPDT contacts and 24 VDC coils. Cross-reference part numbers such as AZ9731-1C-24DC1D2 if coil suppression components differ. Verify physical dimensions and terminal alignment for mechanical fit.
