It seems you're looking for a schematic related to the "F4901 11A 24V" which could refer to a specific electronic component or circuit, possibly related to power supplies, automotive systems, or industrial electronics. Unfortunately, without more context, it's challenging to provide a precise report or schematic. However, I can guide you on how to approach finding such information.

5. Common Circuit Design (Generic 24V Relay)

If you are trying to wire this device, here is the standard schematic for a 24V DC controlled relay switching a load:

      [24V DC Power Supply]
             |
             +----[ Switch ]----[ Resistor ]----( + Input Relay )
             |                                  |
             +----------------------------------( - Input Relay )
[High Power Load Circuit]
      (e.g., 120V/220V AC)
             |
             +----( Relay Output 1 )----[ LOAD ]----( Relay Output 2 )---- Neutral/Return

Note: The resistor on the input side is internal in many "24V input ready" relays. If the datasheet says "Input Voltage: 24V DC", you can connect directly. If it says "Input Voltage Range: 3-32V DC", a resistor is usually built-in.
