Frequently Asked Questions
What voltage and current can the FR120N module handle?
The module’s MOSFET switch is rated for up to 100V and 9.4A continuous current, making it suitable for most low- to mid-power DC applications.
How do I connect the module to a microcontroller?
Use the signal input pin for your 3V or 5V MCU output. The optocoupler isolates the control circuitry—simply wire your microcontroller ground to the module ground and drive the input pin with a high or PWM signal.
Does the module protect against electrical noise and interference?
Yes, the built-in optocoupler isolation separates the control signal from the high-power side, significantly improving noise immunity and protecting your MCU from voltage spikes.
