Product Descriptions
As a countdown timer supplier that accepts various special applications, we can also provide signal output lines for customized modules to control the power switch of electrical appliances. The countdown interval can be set by the user, and the adjustment unit can be seconds, minutes, hours or days. It can also be a time interval preset by the program, that is, a timer with a fixed countdown time, which can be used to remind the regular maintenance of expensive equipment, the replacement of filter elements with a limited service life, or regular activities. .

In this series of countdown timer products, there are two holes at both ends of the case, allowing users to fix them in place with screws.

It has two power input lines and one control signal output line. The power supply voltage is + 1.5V DC. The maximum range that can be set for the countdown is 99 hours and 59 minutes. It is suitable for power control of various electrical appliances or equipment. When the timer starts to count down, it will provide a high potential signal (+1.5V) through the output line. When the count down reaches zero, the potential will drop to (0V).

In addition to this version, there are three versions as follows:

TR140: 9999 minutes
