A61AC24VDC.9

Relay Automotive Overview

The A61AC24VDC.9 is an automotive relay from the CIT A6 series, designed for high-current switching applications. It features a SPST (Single Pole Single Throw) Normally Open contact arrangement with a maximum switching current of 30A at 75VDC. The coil operates on a 24VDC supply, consuming 900mW of power with a resistance of 640 Ohms. Constructed with Silver Tin Oxide (AgSnO2) contacts, it ensures low initial contact resistance below 30 milliohms. The component is RoHS compliant and suitable for automobile and lamp accessory environments.

Relay Automotive Feature Summary

• High switching capacity up to 30A for demanding automotive loads
• Robust AgSnO2 contact material for reliable electrical performance
• Compact design compatible with standard PCB pin and quick connect mounting

Relay Automotive Applications

• Automotive lighting circuits
• Lamp accessories control
• General automotive load switching

Relay Automotive Procurement Notes

Verify the specific suffix configuration against official CIT Relay and Switch documentation to ensure correct sealing options and terminal styles. Confirm that the 24VDC coil voltage matches the system requirements. Cross-reference the part number with authorized distributors to validate authenticity and compliance with current manufacturing standards.

Relay Automotive Selection Notes

Select this model when a SPST Normally Open configuration is required for 24VDC automotive systems. Ensure the application current does not exceed the 30A rating at 75VDC. Consider the physical dimensions and mounting style compatibility with the target PCB or harness assembly before integration.

Relay Automotive Part Context

This component belongs to the CIT A6 series of automotive relays, which are certified under QS-9000 and ISO-9002 standards. The series is engineered for durability in vehicle environments, offering large switching capacities and versatile mounting options including PCB pins and quick connects for efficient assembly.

Relay Automotive Replacement Considerations

Consult official CIT Relay and Switch substitution guides for verified alternatives. Generic replacements may differ in coil resistance, contact material, or mechanical footprint. Verify that any substitute maintains the same SPST NO configuration and 24VDC coil specification.
