Function: Delayed power-off module with adjustable delay time from 1 to 480 minutes. This module cuts off power supply after the preset delay period ends. Suitable for use in living rooms, kitchens, bathrooms, bedrooms, corridors, stairways, and similar areas. Compatible with various devices such as exhaust fans, motors, air coolers, cooling fans, germicidal lamps, humidifiers, and heaters. Operation: Upon powering on, the PWR indicator light stays on steadily, indicating active operation. When the delay period ends, the output power is disconnected and the PWR indicator begins to flash. The module features 16 selectable delay modes: 1, 3, 5, 10, 15, 25, 30, 40, 50, 60, 90, 120, 180, 240, 300, and 480 minutes. Model: IO34H02 Load Capacity: 10A 120VAC / 5A 220VAC Working Power Consumption: 42mA Output Voltage: AC 110–220V Power Supply Voltage: AC 110–220V Maximum Standby Power Consumption: 12mA Control Channels: 1 output Control Load: Incandescent lamp up to 1000W, energy-saving lamp up to 300W Features: Built-in LED indicator to show working status (steady light indicates active timing, flashing light indicates delay completed). Usage Instructions: - Set the desired delay time only when the device is powered off; never adjust during live operation. - After confirming correct wiring, apply power. The module starts working immediately (indicator light remains on). - Once the set time elapses, power supply stops automatically (indicator light flashes). - To turn off prematurely, disconnect the main power supply. - To start a new delay cycle, power the module off and then back on. Safety Notice: Always power off the unit before changing the delay setting. Never perform live adjustments.
