A2H1CSP24VDC1.6R

Relay Automotive Overview

The A2H1CSP24VDC1.6R is a Mini ISO automotive relay manufactured by CIT Relay and Switch. It features a SPDT (1 Form C) contact arrangement with a 24VDC coil voltage. The device supports through-hole mounting and includes an integrated resistor. Key electrical specifications include a maximum switching current of 40A at 14VDC, a maximum switching power of 630W, and a maximum switching voltage of 75VDC. The contact resistance is less than 30 milliohms initially, utilizing AgSnO2 contact material.

Relay Automotive Feature Summary

• Mini ISO form factor designed for compact automotive applications
• Integrated resistor included within the relay assembly
• Capable of switching up to 110VDC for diverse load requirements

Relay Automotive Applications

• Automotive DC motor control systems
• Automotive lamp accessories and lighting circuits
• General-purpose automotive relay modules requiring Mini ISO footprint

Relay Automotive Procurement Notes

Verify that the specific suffix 'R' denotes the inclusion of the internal resistor, as this alters the functional characteristics compared to standard variants without resistors. Confirm the package type matches the required PCB or socket interface. Ensure the coil voltage rating aligns with the target system's power supply to prevent operational failure or component damage during procurement.

Relay Automotive Selection Notes

Select this model when a Mini ISO footprint is required alongside a built-in resistor for circuit protection or suppression. The 24VDC coil voltage must match the vehicle or system architecture. Consider the 40A switching capacity for high-load applications such as motors or lamps. Verify that the SPDT configuration meets the specific signal or power routing needs of the design.

Relay Automotive Part Context

This component belongs to the CIT Mini ISO relay series, which are widely used in automotive environments. These relays are characterized by their small size, light weight, and robust switching capabilities. The series is certified under QS-9000 and ISO-9002 standards, ensuring quality for automotive manufacturing. They are suitable for both PCB pin and quick connect mounting options.

Relay Automotive Replacement Considerations

Cross-reference with other Mini ISO relays from CIT Relay and Switch that share the same 24VDC coil voltage and SPDT contact arrangement. Ensure any substitute part maintains the 40A switching capacity and compatible physical dimensions. Verify if the replacement requires an external resistor if the original part integrates one internally.
