AZ9801-1A-12DR

Relay Automotive Overview

The AZ9801-1A-12DR is a 70 Amp Super-ISO automotive relay manufactured by American Zettler. It features a SPST (Single Pole Single Throw) Normally Open contact arrangement with a 12 VDC coil. The unit includes an integrated parallel resistor and utilizes epoxy sealing for environmental protection. Key electrical specifications include a maximum switched current of 70 A, a maximum switched voltage of 30 VDC, and a resistive load rating of 840 W. The coil operates at 12 VDC with a typical operate time of 7 ms and release time of 5 ms.

Relay Automotive Feature Summary

• SPST Normally Open contact configuration providing single circuit switching capability
• Integrated parallel resistor within the coil circuit for operational stability
• Epoxy sealed construction designed to withstand harsh automotive environments
• High current carrying capacity rated for 70 Amps continuous operation

Relay Automotive Applications

• Automotive high-current accessory circuits
• Lighting systems in vehicles
• Motor control applications
• Power distribution units

Relay Automotive Procurement Notes

Verify that the specific part number AZ9801-1A-12DR matches the required 12VDC coil voltage and 70A current rating. Confirm the presence of the internal parallel resistor and epoxy sealing if these are critical design constraints. Ensure compatibility with Super-ISO mounting standards and quick connect terminal types before finalizing procurement.

Relay Automotive Selection Notes

Select this component when a robust 70 Amp switching solution is required for 12VDC automotive systems. The inclusion of a parallel resistor simplifies driver circuit design compared to standard relays. Consider the epoxy seal for applications exposed to moisture or dust. Verify that the physical dimensions fit the available space in the vehicle's fuse box or relay panel.

Relay Automotive Part Context

This relay belongs to the AZ9801 series of Super-ISO automotive relays from American Zettler. It is distinct from the AZ980 series which typically offers 80 Amp ratings in Mini-ISO packages. The AZ9801 series is specifically engineered for higher current demands in modern vehicles, utilizing a standardized footprint compatible with ISO super-fuse box layouts.

Relay Automotive Replacement Considerations

Direct substitutes may include other 70 Amp Super-ISO relays with 12VDC coils and parallel resistors. Verify mechanical footprint compatibility with existing PCB or panel mounts. Ensure the replacement maintains the same SPST NO contact configuration and epoxy sealing requirements.
