Description:
The DIGITAL TIMER’s operating principle is same as MICROCONTROLLER.
It is also a integrated circuit control system. In general, the
engineer use the integrated circuit technology to make
pre-programmed codes according to the product design requirements.
Then we print these codes in the PCB by digital printing
technology. The next step is integrating those electronic
components with digital processing function, including CPU, RAM,
ROM, relay, etc. in the PCB by HVLSI technology. The digital timer
could control the signal or current operation, including switch-on,
switch-off, timekeeping, counting, and timing etc. In general
application, we could use the digital timer to manage and control
some electrical components in oven by I/O system. It is a good
upgraded replacement for traditional mechano-electronic control
units in oven machines. In our product list, you could find below
four kinds of digital timer.
Functions:
a. color function, 24-hour time
b. alarm fuction, set within 24 hours, ring tones selectable 3 type
c. appointment oven working hours, can be arbitrarily set within 24
hours
d. oven can be set working hours, the longest 10 hours of setting

Advantages:
Full range of product
Stable working quality and long lifetime service
1) We choose the best electronic components to manufacture the
digital timer. All of these components which produced by famous
electronic components factories all could continuously stably work
for long time.
2) In our production process, we use the advanced mould technology
to guarantee the good quality of housing parts. The good dimension
accuracy of parts could guarantee the long life work of a switch.
Working stably under high temperature
The raw materials of the parts for switch all have good high
temperature resistance properties. So the switch could work stably
under the high temperature, at least 125 degrees centigrade.
