Function: Provides a time delay before cutting off the power supply. Compact size and easy to use. Reliable performance. This module is a time-delay shutdown device. After the preset delay period elapses, it automatically interrupts 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 (maximum 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 indicates active operation; flashing indicates delay completed) 16 selectable delay settings: 1, 3, 5, 10, 15, 25, 30, 40, 50, 60, 90, 120, 180, 240, 300, and 480 minutes Operational behavior: Upon power-up, the PWR LED remains steadily lit; when the delay ends, the PWR LED flashes. Instructions: ① Set the desired delay time (live adjustment is not supported). ② Verify correct wiring, then apply power. The module activates immediately (PWR LED stays on); upon timeout, power output stops (PWR LED flashes). - To terminate operation earlier, disconnect the main power supply to the module. - To initiate a new delay cycle, power the module again. Color: As shown Material: PCB + electronic components Style: Option A (without housing) / Option B (with housing) Slight appearance variations may occur between production batches; these do not affect functionality. Package includes: 1 × Delay Relay Switch
