This is a daily power On/Off time switch module in compact size. Allow people to set up to 7 channels in a day. Furthermore, it has cycling switch too. People can set on/off interval repeatly from 1 minutes up to 23 hours 59 minutes.
It is measured of 34 x 22 mm in width and height, and 8 mm as thickness. It is good to installed in a electrically powered device, such as electric fan, coffee maker, rice cooker, motor, to manipulate the "on" or "off " of their power source.
The module is metal framed with 16 connection pins with 2 mm pitched. Good to mount on main board. To keep the setting data properly a 3.0 volts backup battery is suggested to apply. Low voltage detection circuit is built-in the module to check the power of backup battery. When its voltage is measured less than 2.7V, a "low battery" sign is appeared in blinking to warning battery replacement.
As well as setting the daily "on" and "off" time (up to 7 channels), it is possible to set the identical interval of "on" and "off" period, called as "cycling mode".
In additional to the above two modes, regular daily time On/Off, and cycling, to set the timer as a combination of the two modes is possible too. Please refer to the attached illustration drawing to see the time chart.
