A11CSQ24VDC1.5R

Relay Automotive Overview

The A11CSQ24VDC1.5R is a general-purpose power relay manufactured by CIT Relay and Switch, designed for through-hole or plug-in mounting with quick-connect terminals measuring 0.187 inches (4.7mm). It features an SPDT (1 Form C) contact configuration capable of switching up to 30 Amperes at a maximum voltage of 75VDC. The coil operates on 24VDC with a current draw of 62.5mA and includes an integrated resistor. Key electrical parameters include a coil resistance of approximately 384 Ohms, an operate time of 10ms, and a release time of 7ms. The unit is sealed, non-latching, and rated for operation between -40°C and 85°C.

Relay Automotive Procurement Notes

Verify the specific terminal pitch matches your PCB footprint requirements before ordering. Confirm that the 30A rating aligns with your peak load currents to ensure reliability. Check for RoHS compliance status if your manufacturing process mandates it. Ensure the operating temperature range suits your intended environment. Review the datasheet for precise mechanical dimensions to avoid clearance issues during installation.

Relay Automotive Selection Notes

Select this model when a 30A switching capability is required rather than standard signal relay limits. The 24VDC coil voltage makes it suitable for industrial control systems. Consider the quick-connect termination if panel wiring efficiency is prioritized over direct PCB soldering. Compare against lower-current alternatives if the load does not exceed 2A to optimize cost. Verify the SPDT configuration meets the specific switching logic needs of the application.

Relay Automotive Part Context

This component belongs to the A11CSQ series of power relays from CIT Relay and Switch. The series is characterized by high current handling and robust construction for industrial environments. Similar models in the lineup vary primarily by coil voltage and contact material specifications. The A11CSQ designation indicates a specific form factor and terminal style within the manufacturer's broader portfolio of electromechanical switching devices.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT models with identical 30A ratings and 24VDC coils, such as variants within the same A11CSQ family. Cross-manufacturer replacements require matching the 30A/75VDC rating, SPDT configuration, and 0.187-inch quick-connect terminals. Verify coil resistance and actuation times to ensure equivalent performance characteristics in the target circuit.
