1.Description:
It is a power-off delay relay module.When the module senses the signal voltage input,the relay turns on;when the signal voltage stops input,the relay turns off after a period of delay.It can be used for signal monitoring,automatic door closing and other scenes.
2.Feature:
1).It has a four-gear delay time range,and the delay time can be selected by the switch.
2).It has a long service life and can support 100,000 times of use.
3).Its power consumption is small,less than 1W,and it consumes less power.
4).It is responsive,and detection is fast and accurate.
5).It has high precision,stable and reliable performance.
3.Parameter:
1).Product Name:Power-off Delay Relay Module
2).Input Voltage:DC 4.5V-6V
3).Power Consumption:1W
4).Time Gear:
First Gear:0.2 seconds -30 seconds,accuracy:0.1 seconds
Second Gear:range from 0.2 seconds to 300 seconds (5 minutes),accuracy:0.3 seconds.
Three Gears:range from 0.2 seconds to 30 minutes,accuracy:1.8 seconds.
Four Gears:range from 0.2 seconds to 300 minutes (5 hours),accuracy:18 seconds
5).Life:100,000 actions
6).Input Voltage Signal:1.5V or more is an effective signal,and the current needs at least 0.1mA
6).Work Temperature:-25℃~85℃
7).Work Humidity:5%~95%RH
8).Size:72*25*25mm
4.Interface Definition:
1).V+:The positive pole of the module's DC power supply
2).GND:The negative pole of the module's DC power supply,which is also the reference GND for the signal voltage
3).IN:Signal voltage input,below 1V is low level,and above 1.5V is high level.Withstand up to 30V.
4).NO:Normally open contact of the relay
5).NC:Normally contact of the relay
6).COM:Relay contact common terminal
5.Instructions:
1).Time range setting:
1.1).When the selector switch is placed in the 30 position,it means 0-30 is adjustable.
1.2).When the selector switch is placed in the 300 position,it means 0-300 is adjustable.
2).Adjustment of time value:
1.1).The adjustable resistor rotates counterclockwise to the "-" sign to decrease the time,and rotates clockwise to the "+" sign to increase the time.
3).Setting of time unit:
1.1).When the selector switch is placed in the Sec position,the unit is:seconds.
1.2).When the selector switch is placed in the Min position,the unit is:minutes.
4).For Example:Request a 50-minute delay:
1.1).The scope is placed at the 300 position.
1.2).The time unit is placed in the Min position.
1.3).Adjust the adjustable resistance to the 50 position,and the full adjustment is 300,so if it is adjusted to 1/5,it is 50.
1.4).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=12
Ut is the voltage measured by the multimeter,30 is the range selected by the selector switch,and it can also be selected to 300.
6.Application(Combined with travel switch and induction switch to achieve):
1).Automatically close the door over time
2).Flow monitoring of assembly line products
3).Monitoring of interruption of water flow,air flow,etc
4).Other uses
