Mini-Timer Module - 99M59S

Product Descriptions
This timer module has 99 minutes 59 seconds countdown capacity, with 1 second resolution, and 1 second of minimum setting interval.

This miniature module sized as 35 x 18.4 mm with 10.1 mm thickness. LCD screen size is 20 x 10.92 mm with 4 rubber soft buttons for minute set, second set, start/stop/recall, and screen reset. When time's up, the piezo buzzer goes off for one minute normally. The emphasized volume of piezo alarm sound can reach to more than 80 dB.

As people know the most important feature for a timer is steady reminding user the time is up. But it wastes too much power, especially for battery operated device, and becomes difficult to make. Under our R/D team’s effort, we designed a special program called PSEA (power saving endless alert) to make this feature become possible. This unique feature is available upon request. Normally the module provides one minute alert.

If required, this module can provide open collector output pole to allow people use it to control other electrical power operated device.
