F4901 11a 24v Schematic Install New!

Push the prepared crimp connectors firmly onto the corresponding relay pins based on your schematic configuration. Double-check that no stray wire strands stick out from the terminal barrels, as loose strands can easily cause dangerous cross-pin short circuits. 5. Flyback Diode Protection (Critical Step)

Before connecting wires to the device, you must understand the physical pins and their electrical limits. Standard variants of the F4901-11A series handle high-amperage loads (typically between 10A and 40A depending on the specific manufacturer footprint, such as standard automotive ISO styles or specialized PCB footprints). Electrical Limits 24V DC (Nominal) Coil Current draw: Usually between 30mA and 90mA

Connect your 24V control signal (from your PLC or safety controller) to the coil terminals (usually 2 and 10). Integrating Safety Inputs: For safety interface applications, the Banner IM-T-11A f4901 11a 24v schematic install

At 11A, conduction loss = I² × Rds(on) = 121 × 0.012 = 1.45 W. With RθJA ~ 45°C/W (natural convection), temperature rise ≈ 65°C above ambient. For 50°C ambient, case temp = 115°C (acceptable for industrial grade). For higher ambient, forced air or reduce current to 9A.

When a 24V relay coil turns off, its collapsing magnetic field generates a massive reverse-voltage spike. This spike can easily destroy PLCs, transistors, and microcontrollers. Push the prepared crimp connectors firmly onto the
