A11CSP24VDC1.2D

Relay Automotive Overview

The A11CSP24VDC1.2D is a sealed automotive relay manufactured by CIT Relay and Switch, designed for through-hole mounting. It features an SPDT (Single Pole Double Throw) contact arrangement with a maximum switching capacity of 30A at 75V DC. The coil operates on 24V DC, requiring 18V to activate and releasing at 2.4V. Electrical performance includes a maximum operate time of 10ms and a release time of 7ms. Initial contact resistance is specified at 50mΩ, ensuring reliable signal and power transmission in automotive applications.

Relay Automotive Feature Summary

• Fully sealed construction protects internal components from environmental factors
• SPDT configuration provides versatile circuit control capabilities
• Through-hole pin mounting ensures secure PCB integration

Relay Automotive Applications

• Automotive electrical systems
• Industrial control circuits
• General purpose switching applications

Relay Automotive Procurement Notes

Verify the specific ordering suffix matches the required contact arrangement and coil voltage. Confirm that the sealed design meets the environmental protection requirements of the target application. Ensure the through-hole footprint aligns with the printed circuit board layout specifications before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a 24V DC coil actuation is required for automotive or industrial environments. The SPDT contact type allows for changing between two circuits. Consider the 30A current rating and 75V DC voltage limit to ensure the load does not exceed the relay's maximum switching capacity during operation.

Relay Automotive Part Context

This part belongs to the CIT automotive relay series, characterized by robust sealing and high current handling. The model designation indicates a 24V DC coil variant with specific timing characteristics. It serves as a critical interface component for controlling higher power loads using lower power control signals in vehicle electronics.

Relay Automotive Replacement Considerations

Direct substitutes must match the 24V DC coil voltage, SPDT contact form, and 30A current rating. Verify that alternative relays offer comparable operating and release times. Ensure the replacement component maintains the same sealed construction and through-hole mounting style for physical compatibility.
