Upfitter Auxiliary Switches (RPO 9L7)
- Never go beyond its capabilities. Try to stay 10 to 15% below what the rate is for
- 12-volt 5-prong relay. Excellent water-repellent and dustproof ability, but not using it in water
- Be careful when inserting the relay into the socket. If you force it, you will bend the female connectors
- Primary leads use 12 a.w.g tinned copper wire. Coil leads use 16 a.w.g
- Nominal Coil Voltage: 12 V DC; Coil Power: 1.8 W; Coil Resistance: 80 Ω; Must Operate Voltage: 6~8 V DC; Must Release Voltage: 0.6~3.6 V DC; Maximum Applied Voltage: 15.6 V DC
- Integrated Diode: Each relay includes a built-in diode that suppresses induced voltage during switching, safeguarding your electrical components from potential damage.
- Small size/Low power consumption/High contact voltage/ High sensitivity.
- Contact Material: Ag Alloy / Contact Resistance: ≤ 100MΩ.
- Minimum operating voltage 8V, corresponding minimum operating current is 100mA; Standard operating voltage 12V, corresponding standard operating current is 150mA.
- Life Expectancy Electrical: 100,000 Operation, Life Expectancy Mechanical: 10,000,000 Operation.
- High switching capability: Normally open 40A/14V DC and normally close 30A/14V DC. Suitable for Nilight LED light bar wiring harness kit
