Detail
This module is a timer relay module with high precision, stable and reliable performance.
Fine workmanship, good performance and long service life.
Delay fan special module, off delay disconnect module specifically for cooling fans, exhaust fans, etc. delay.
Easy to understand function, turn on the output when there is a signal, turn off the output when the signal disappears.
4-speed adjustable, easy to operate, zero standby power consumption, power saving and safety.
Name: Power-off delay disconnect module
Model: QF-RD21F
Voltage: AC 100V-220V
Power consumption: <1.0W standby zero power consumption
Time range: (4 gears, selected by switch)
First gear: range 0.2 seconds-30 seconds, precision: 0.1 seconds
Second gear: range 0.2 seconds -300 seconds (5 minutes), precision: 0.3 seconds
Third gear: range 0.2 seconds-30 minutes, accuracy: 1.8 seconds
Fourth gear: range 0.2 seconds-300 minutes (5 hours), precision: 18 seconds
Output: output voltage is the same as input voltage, maximum power supply capacity is 10A
Life: 100,000 times action
Function: turn on the output when there is a signal, turn off the output when the signal disappears
Size: length 88mm * width 36mm * height 22mm
Screw hole: center distance 83mm * 31mm, hole diameter 3.2mm
L: Fire wire access
L2: switch output side fire wire, taken from the heating body fire wire
N: zero line (public)
FAN: fan output, fire wire
Operating instructions:
Setting of time range.
When the selector switch is placed in the 30 position, it means 0-30 adjustable
When the selector switch is placed in the 300 position, it means 0-300 adjustable
Adjustment of time value:
Adjustable resistor rotates counterclockwise in the - direction to reduce the time, and clockwise in the + direction to increase the time
Setting of time unit:
When the selector switch is in the Sec position, the unit is: seconds
When the selector switch is in the Min position, the unit is: minutes
Example.
50 minutes delay time is required:
1. Range set to 300 position
2. Time unit placed in the Min position
3. Adjustable resistor adjustment to the 50 position, adjust the full for 300, so adjust to 1/5 that is 50.
Note: The potentiometer adjustment can also be adjusted quickly with a multimeter voltage file. For example, the range 30, need to be adjusted to 12, then the voltage can be adjusted to 2.
t=Ut/5*30=2.0V / 5.0V * 30 =12
Ut is the voltage measured by the multimeter, 30 is the range selected by the selector switch, you can also choose to 300
1. Delay a period of time after the heating equipment is turned off before turning off the fan.
2. Exhaust fan in the switch off after the delay off, not necessarily need heating device
