Function: Provides a time-delayed power cutoff. Compact size and easy to use. Reliable performance. This module is a time-delay shutdown device. After the preset delay period elapses, it cuts off the power supply. Suitable for various applications, including exhaust fans, motors, air coolers, cooling fans, UV germicidal lamps, humidifiers, and heaters. Ideal for use in living rooms, kitchens, bathrooms, bedrooms, hallways, and staircases. Specifications: Output current: 7A (max 10A) Operating power consumption: 43mA Output voltage: AC 110–220V Supply voltage: AC 110–220V Maximum standby power consumption: 12mA Number of control channels: 1 output Operating temperature: -25°C to +85°C Operating humidity: 5%–95% RH Load capacity: Up to 1400W for incandescent lamps; up to 300W for energy-saving lamps LED indicator shows operational status (steady light = active; flashing = delay complete) 16 selectable delay settings: 1, 3, 5, 10, 15, 25, 30, 40, 50, 60, 90, 120, 180, 240, 300, and 480 minutes Status indication: Power-on indicator (PWR) remains lit during operation; flashes after delay completion Instructions: ① Set the desired delay time (live adjustment not supported). ② Verify correct wiring, then apply power. The module activates immediately (PWR LED stays on); upon delay completion, power output stops and the PWR LED flashes. — To terminate operation early, disconnect the main power supply. — To initiate a new delay cycle, power on again.
