F4901 11a 24v Schematic Install [work] Jun 2026

Do not parallel F4901 units directly without current balancing (e.g., 0.1Ω ballast resistors). Internal Rds(on) variation leads to uneven sharing.

| Wire Color (Typical) | Function | Description | | :--- | :--- | :--- | | | Power (+) | Connect to Constant 24V Power (Battery Positive). | | Black | Ground (-) | Connect to Vehicle Chassis Ground or Battery Negative. | | Yellow | Ignition (ACC) | Connect to the vehicle's ignition key switch (24V when key is ON). | | Orange | Relay Output | Used to control an external relay (e.g., fuel cut-off/immobilizer). | | White | CAN High | Connects to Vehicle CAN Bus High line. | | Green | CAN Low | Connects to Vehicle CAN Bus Low line. | | Blue | Digital Input 1 | Typically used for SOS button or Door sensor. | | Other Colors | Analog/Input | Used for fuel sensors or temperature sensors. |

Tighten all screw terminals down securely to a torque specification of approximately to minimize contact resistance, which avoids localized overheating. 4. Troubleshooting and Commissioning Checklists

Heavy-duty, screw-down terminal distribution points. System Architecture Schematic

The positive terminal that goes directly to the device you are powering (e.g., motor, heater, solenoid).

These are typically the coil pins. Connect your 24V DC positive and negative supply here to energize the relay. Common Terminals: Terminals 1, 6, and 11: Do not parallel F4901 units directly without current

What (e.g., LED light bar, pump, fan) are you powering?

Before switching on the main breaker, use this quick checklist to confirm your circuit's electrical integrity. Pre-Power Checklist

First, power the unit and check the output with a multimeter set to DC voltage. It should read approximately Grounding: Always connect the | | Black | Ground (-) | Connect

If switching inductive loads (like large motors or solenoids), use a Coil Surge Suppression Unit to prevent contact pitting. Manual Testing:

While "F4901" is a generic reference that appears in various technical manuals (such as for tractors or specialized
