A102CS12VDC

Relay Automotive Overview

The A102CS12VDC is an automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a DPDT (Double Pole Double Throw) contact configuration, providing two independent Form C circuits within a single compact package. The device operates with a 12VDC coil voltage and draws a coil current of 47.2 mA. It supports a maximum contact rating of 30 Amps, making it suitable for demanding automotive loads. The unit utilizes PC board mounting for secure integration into vehicle electrical systems.

Relay Automotive Feature Summary

• Dual independent switching channels via DPDT contact form
• High current capacity rated at 30 Amps per circuit
• Designed specifically for automotive electrical environments
• Single-side operating function for reliable control

Relay Automotive Applications

• Automotive lighting control systems
• Vehicle accessory power distribution
• Motor control circuits in automotive assemblies
• General purpose high-current switching in vehicles

Relay Automotive Procurement Notes

Verify the specific contact configuration requirements against the DPDT specification before procurement. Ensure the PCB footprint matches the manufacturer's recommended land pattern for PC board mounting. Confirm that the 12VDC coil voltage aligns with the vehicle's nominal electrical system to prevent under-voltage operation or excessive coil heating during continuous duty cycles.

Relay Automotive Selection Notes

Select this component when dual isolated switching paths are required within a single relay housing. The 30A rating accommodates heavy loads such as headlights or fuel pumps. Consider the physical dimensions and pinout compatibility with the target PCB design. Evaluate thermal management needs if the relay will operate continuously near its maximum current rating in enclosed engine compartments.

Relay Automotive Part Context

This part belongs to CIT Relay and Switch's automotive relay portfolio, which focuses on robust components for vehicle electronics. The A102 series typically offers standard automotive form factors compatible with common relay sockets or direct PCB mounting. It serves as a critical interface component between low-power control signals and high-power automotive loads.

Relay Automotive Replacement Considerations

Direct substitutes must match the DPDT contact form, 30A current rating, and 12VDC coil specifications. Verify mechanical footprint compatibility for PC board installation. Cross-reference pin assignments to ensure correct signal routing without rewiring modifications.
