12V timing switch cycle time time delay switch relay

LC one channel timing switch relay module carries 8 bit high quality microprocessor of ST company .It can control the relay to have the function with one or cycle timing switch .It has three digital LED to show the time .This module is to control magnetic valve ,electrical machine, strip light ,product aging test and so on

Functions :

1.It has strong anti-interference capability ,good stability because its structure ofonboard STM8S high performance microprocessor and EL817,

2.three digital LED of panel shows real time

3.with 12V,10A/250VAC,10A/30VDC relay, it can continuously absorb 100,000 times .

4.with relay statue indicator (D2),Light on for actuation ,light off for release

5.with four 6X6mm button (one reset button ,three functional buttons )

6. set separately for last time of relay on (T1)and off (T2)

7.four modes are optional : first mode :one timing per 1-9999minutessecond mode :cycle timing per 1-999minutesThird mode : one timing per 1-999sFourth mode :cycle timing per 1-999s

8 working current :60mA

9 working voltage :DC12V

10.The board size: 42*60mm

Hardware specification

1.interface instruction :

VCC.GND : positive and negative

COM: common interface of relay

NO: normal open .When relay is off ,NO and COM disconnect ,current is short when relay connects

NC: normal close .When relay is off, NC and COM is on short current

2.function for button

RST: reset button ,reset to fault factory setting

S1: mode button ,set working mode and timing time

S2 : reduce /add button ,set exact value of mode and timing

S3:Start/stop button,

Start button :connect relay and and work again based on former setting time

Stop button :turn off relay and stop timing (display show "000")

It goes to mode and timing by press S1 . Continuous press S1 to move the small dot, dot location where represents value . Press S2 to set mode and periodic time T1 and T2 (set T1only when it is on Mode1 and mode 3 ).press S1 to exit .At this moment,the small dot disappear, then press the start button S3, relay is on , the LED light D2 is on , the value is -1,means that it work properly to begin

Setting method for mode 1 is same as mode 3,mode2 is same as mode 4.Now,we take mode 1 and mode 2 setting for example

Steps for setting mode 1

(1)press the mode key S1 (display "p-1."), and then change the mode value by S2 (1--4 optional)

(2)Press S1, the dot is positioned at the 100 position of the time T1 of the relay, and then changes the 100 position value of T1 by press S2 (0--9 optional).

(3)Repeat steps 2 twice to set the tens and the ones place of T1 respectively.

(4)Press S1 to exit ,small dot disappear

(5)press the start button S3, relay is on , the LED light D2 is on , the value is -1,means that it work properly

(6)The relay will be off automatically when T1 is over ,LED D2 will be out also ,and led display show "000"

(7)Press S3 to continue the former setting time when relay is connected again . In addition, It will turn off the relay if press S3 again and timing is over ,LED display shows"000",

Steps for setting mode 2

(1)press the mode key S1 (display "p-1."), and then change the mode value by S2 (1--4 optional)

(2)Press S1, the dot is positioned at the 100 position of the time T1 of the relay, and then changes the 100 position value of T1 by press S2 (0--9 optional).

(3)Repeat steps 2 twice to set the tens and the ones place of T1 respectively.;

(4)Press S1, the dot is positioned at the 100 position of the time T1 of the relay, and then changes the 100 position value of T1 according to S2 (0--9 optional).

(5)Repeat steps 4 twice to set the tens and the ones place of T1 respectively.;

(6)Press S1 to exit ,small dot disappear;

(7)press the start button S3, relay is on , the LED light D2 is on , the value is -1,means that it work properly;

(8)

The relay will be off when T1 is over ,LED light D2 is out ,Digital tube shows T2 countdown. The relay will connect when T2 is over ,LED light D2 is on ,digital tube shows T1 countdown ....repeat again and again

(9)press S3 to stop timing when it is on timer 1,and digital tube shows 000 .When it is on timer T2,press S3 to restart timing T1,T2 based on the former setting time .
