I have to drive two brakes for two stepper motors. The brake datasheet does not provide many details, I only know that the driving voltage is 24V and the power is 5W, I don't know the winding inductance. However from these data, I assume that the RDC of the brake inductor is 120ohm. My CPU provide 3V3 output logic levels.
My schematics looks like below. Since I have no experience with these brakes, I would check if there are same factor I have missed.
