A42US24VDC

Relay Automotive Overview

The A42US24VDC is a dual package automotive electromechanical relay manufactured by CIT Relay and Switch. It features a 24 VDC coil voltage with a non-latching operating function. The contact configuration consists of two single-pole single-throw normally open (SPST-NO) circuits, each rated for 10 Amps. Maximum switching capacity is defined at 380VAC and 75VDC limits. The unit utilizes PC board mounting with sealed construction and operates within a temperature range of -40°C to 85°C.

Relay Automotive Feature Summary

• Dual package design providing two independent SPST-NO circuits in a single housing
• Automotive-grade sealed construction ensuring environmental protection
• Low coil power consumption characteristics suitable for vehicle electrical systems
• PC pin termination style facilitating direct printed circuit board integration

Relay Automotive Applications

• Automotive lighting control circuits
• Vehicle accessory power distribution
• Industrial control panel signal switching
• General purpose high-current load management

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct coil voltage and contact configuration. Confirm that the dual package variant matches system requirements for isolated or common ground connections. Check RoHS compliance status and moisture sensitivity level prior to procurement to align with assembly process standards.

Relay Automotive Selection Notes

Select this component when dual-channel switching is required within a compact form factor. Ensure the 24 VDC coil voltage matches the available control supply. Verify that the 10A per pole rating satisfies the maximum load current requirements. Consider the sealed nature of the device if exposure to harsh environments is anticipated during operation.

Relay Automotive Part Context

This model belongs to the CIT automotive relay series designed for robust performance in vehicular applications. The dual package architecture allows space-efficient implementation of multiple switching functions. It complements other CIT offerings like the A41CS24VDC by providing parallel channel capability rather than single changeover contacts.

Relay Automotive Replacement Considerations

Direct substitutes must match the 24 VDC coil specification and dual SPST-NO contact arrangement. Verify physical footprint compatibility for PCB mounting. Ensure equivalent current ratings and sealing standards are maintained to preserve system reliability and safety certifications.
