USB Intelligent Control Switch Key benefits Simple USB control: Provides an easy way to switch power circuits from a USB interface, enabling automation, timed control, or remote switching without complex wiring. Reliable, performance control: Onboard performance microcontroller chip manages switching logic for accurate, repeatable operation and stable performance. Robust switching capacity: Builtin relay rated for 10A at 250VAC and 10A at 30VDC, driven by a 5V coil — suitable for many lighting, motor, and appliance loads within those limits. Long service life and protection: Relay is rated for continuous pull life of 100,000 operations. The module includes overcurrent protection and a freewheeling diode to protect the relay coil and downstream electronics from current surges and inductive spikes. Functions and compatibility USB intelligent control switch: Use the USB interface to command the switch from a PC, embedded USB host, or other USBcapable controllers. The onboard microcontroller handles timing and switching tasks internally. Versatile module form: Relay module with onboard protections and driver electronics ready for integration into projects, test benches, control panels, or appliance interfaces. Performance focus: Designed to switch AC or DC loads up to the stated ratings reliably, with protection features that minimize damage from overcurrent or inductive kickback. Practical applications Home automation: Control lighting, fans, or small appliances directly via USB when load current is within 10A at 250VAC or 10A at 30VDC. Prototyping and test setups: Use as a controlled relay output for lab equipment or development boards where USBbased control and reliable switching cycles are needed. Industrial/automation control: Drive solenoids, pumps, or DC motors (within the 30VDC/10A limit) with added overcurrent protection and freewheeling diode protection to extend component life. What makes it stand out Integrated microcontroller for precise, autonomous switching behavior. Clear electrical ratings and long relay life (100,000 continuous pull operations). Builtin safety protections (overcurrent and freewheeling diode) to protect both the relay and connected circuits.
