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".
