A11ASQ24VDC1.5D

Relay Automotive Overview

The A11ASQ24VDC1.5D is a sealed automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a maximum switching capacity of 30A at 24VDC. The coil operates on 24VDC with a non-latching design, drawing 62.5mA. Key electrical parameters include a maximum switching voltage of 75VDC, an operate time of 10ms, and a release time of 7ms. The unit utilizes quick-connect terminals for mounting and is rated for operation between -40°C and 85°C.

Relay Automotive Feature Summary

• High current switching capability up to 30A for demanding automotive loads
• Sealed construction providing environmental protection against moisture and dust
• Non-latching coil design ensuring standard on/off control functionality

Relay Automotive Applications

• Automotive lighting circuits
• Electric motor control in vehicles
• Heater and fan systems
• Auxiliary power distribution modules

Relay Automotive Procurement Notes

Verify the specific suffix '1.5D' against official CIT documentation to confirm terminal type and internal diode inclusion. Ensure the application voltage matches the 24VDC coil rating. Confirm that the 30A load capacity exceeds peak circuit requirements. Check compatibility with existing harness connectors for quick-connect terminals. Validate RoHS3 compliance if required by regional regulations.

Relay Automotive Selection Notes

Select this model when a robust, sealed relay is needed for high-amperage DC loads within automotive environments. The SPST-NO configuration suits simple on/off control tasks. Consider the 75VDC max switching voltage limit for circuit design. The compact form factor allows installation in tight engine bay spaces. Compare operate and release times against system timing requirements.

Relay Automotive Part Context

This component belongs to the A1 series of automotive relays from CIT Relay and Switch. It is part of a family of sealed electro-mechanical switches designed for harsh operating conditions. The series typically includes variants with different contact configurations and current ratings, all sharing similar sealing standards and mounting interfaces for interchangeability within specific design constraints.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT A-series relays with identical 30A SPST-NO specifications and 24VDC coils. Verify that any replacement maintains the same quick-connect terminal style and physical footprint. Cross-reference datasheets to ensure equivalent operate/release times and sealing ratings.
