– Primary DC input power line. Requires heavy-gauge wire (minimum 14 AWG) to minimize resistance losses at high input current.
: If this matches your part, you need the manufacturer's datasheet. These are technical documents, not circuit schematics. Search for AF4901PSA datasheet PDF or look up AF4901PSLA-VB . Sites like alldatasheet.com or manufacturers like Anachip Corp and Diodes Incorporated are good sources.
If your device has "no backlight" but the screen shows a faint image, the F4901 fuse may be blown or "open".
: It acts as a safety barrier between the main battery/adapter power ( DCBATOUT ) and the LCD/Inverter connector to prevent overcurrent damage. Circuit Location : f4901 11a 24v schematic new

If this is for a specific piece of equipment like a or truck , could you share the brand and model of the machine it belongs to? Knowing the manufacturer (e.g., Bosch, Delco Remy, or a specific engine brand) would allow for a more precise wiring diagram. Elettrostart Solenoid, 24V E-4623A - BermanTec
The represents a high-capacity industrial power distribution or control relay module engineered for demanding 24V DC environments. Designed to handle an 11-ampere load, this component acts as a critical gateway in automation pipelines, heavy machinery, automotive subsystems, and specialized safety interfaces. Obtaining an updated, accurate schematic is paramount when integrating this hardware into a new control panel or diagnosing an existing system deployment. – Primary DC input power line
Requires a flyback diode (e.g., 1N5408) to prevent circuit damage
The F4901 uses a traditional voltage divider feeding into the FB (Feedback) pin. However, the new schematic replaces a fixed resistor with a or a precision TL431 with optocoupler if isolation is required. The target voltage is precisely 24.0V ± 2%, with a divider ratio of (Rtop/Rbottom) = (Vout/Vref - 1). Given Vref of the F4901 is typically 2.5V, Rtop would be 86.6kΩ and Rbottom 10kΩ.
When integrating the new F4901-11A module into your system panel, follow this standard wire map: Pin Number Terminal Label Wire Gauge (Recommended) Description Main positive power input from the battery or DC supply. Pin 2 Common system ground and return path. Pin 3 Primary control signal input (Active High). Pin 4 Secondary control signal input (Application dependent). Pin 5 Isolated signal ground reference for control inputs. Pin 6 No Connection / Internal test point only. Pin 7 OUT 1 (NO) Normally Open output path for Load 1. Pin 8 OUT 1 (COM) Common supply feed for Output 1 switching element. Pin 9 OUT 2 (NO) Normally Open output path for Load 2. Pin 10 OUT 2 (COM) Common supply feed for Output 2 switching element. Pin 11 Diagnostic output line (Pulls to GND when a fault occurs). Installation Best Practices These are technical documents, not circuit schematics
