Features:* This module is a timing relay module with high precision, stable and reliable performance.* Fine workmanship, good performance and long service life.* Delay fan dedicated module, closing delay off module is specially used for the delay of cooling fan, exhaust fan, etc.* The function is easy to understand. Turn on the output when there is a signal, and turn off the output when the signal disappears.* 4 gears are adjustable, easy to operate, zero standby power consumption, power saving and safe.Specification:* Name: Power-off delay disconnection module, dedicated to delay fans* Model: QF-RD21F* Function: Turn on the output when there is a signal, and turn off the output after a delay after the signal disappears* Voltage: 100V-220V AC mains* Power consumption: <1.0W standby zero power consumption* Time range: (4 files, selected by switch)1. 1 gear: range 0.2 seconds to 30 seconds, accuracy: 0.1 seconds2. Second gear: range 0.2 seconds-300 seconds (5 minutes), accuracy: 0.3 seconds3. Third gear: range 0.2 seconds-30 minutes, accuracy: 1.8 seconds4. Fourth gear: range 0.2 seconds-300 minutes (5 hours), accuracy: 18 seconds* Output: The output voltage is the same as the input voltage, and the maximum power supply capacity is 10A.* Lifespan: 100,000 actions* Dimensions: length 88mm * width 36mm * height below 22mm* Screw hole: center distance 83mm * 31mm, hole diameter 3.2mm* Matching shell: the shell matches QF-2#, note that only the two screw holes on the long side can be installed.* Package content:1 x relay moduleTerminalL FireWire accessThe live wire on the output side of the L2 switch is taken from the live wire of the heating elementN neutral wire (common)FAN fan output, live wire InstructionsTime range setting:When the selector switch is in the 30 position, it means that 0-30 is adjustableWhen the selector switch is in the 300 position, it means that 0-300 is adjustableAdjustment of the time value:The adjustable resistor rotates counterclockwise in the direction of - sign to decrease the time, and turns clockwise in the direction of + sign to increase the timeTime unit setting:When the selector switch is in the Sec position, the unit is: secondWhen the selector switch is in the Min position, the unit is: minuteExample:Request a 50 minute delay:1. Set the range to 3002. The time unit is placed in the Min position3. The adjustable resistance is adjusted to 50 position, and the full adjustment is 300, so it is 50 when it is adjusted to 1/5.Note: The adjustment of the potentiometer can also be quickly adjusted with the multimeter voltage file. For example, if the range is 30, it needs to be adjusted to 12, then the voltage can be adjusted to 2.t=Ut/5*30=2.0V / 5.0V * 30 =12Ut is the voltage measured by the multimeter, 30 is the range selected by the selector switch, and it can also be selected to 300Note:1.
