Welcome to our shop! This switch control module is a FET module that ensures complete isolation between the input and output. It features a signal trigger terminal with digital high and low electrical levels, allowing it to be connected to a variety of devices such as a microcontroller IO port, PLC interface, and DC power supply. With this module, you can control high-power equipment such as motors, bulbs, LED strips, DC motors, micro pumps, and solenoid valves. It allows you to control these devices with small voltages and currents. The module uses the original F5305S power FET, which enables you to input PWM signals to control motor speed and lamp brightness. Item Type: Switch Control Board FET Module: Input completely isolated from the output Signal Trigger Terminal: Digital high and low level (Can be connected to microcontroller IO port, PLC interface, DC power supply, etc.) Input Signal Voltage: 3V~24V; Current: About 5mA Output Controlled Voltage: 5V~36V, Current: Less than 5A (If larger than 5A, heat sink should be added and the maximum should not exceed 20A) We strive for 100% customer satisfaction.
