Digital Programmable Timers

Our ALFTECH Digital Programmable Timer was designed to meet the needs for an easy programmable school bell timer, to activate sirens on factory floors to alert shift changes or breaks, or any similar application where an external device needs to be triggered at a specific time on a daily or weekly schedule. We have found industrial timers as commonly used for the above applications too complicated and time consuming to program for non-technical users, and have designed our software to be as easy as possible to use for occasional and non-technical users.

The updated DPT-Console v 3.2, our Microsoft® Windows based graphical user interface software allow easy creation of scheduled events which are downloaded and stored in the DPT Hardware's onboard Flash memory.

Download and install DPT-Console V 3.2 Application Software (fully functional, does not require DPT Hardware to create schedules. Your project setup files [.dpt] can be downloaded to a connected DPT Hardware at a later time)

Just a few facts to consider about using the DPT-EN3:

The DPT-EN3 is USB powered, and needs to be connected to a Microsoft Windows based PC for operation, and the charging of its internal batteries. Alternatively, a "powered USB Hub" can provide continuous and un-interrupted power.
The DPT-EN3 can run on its internal batteries for approximately 7 days if the computer is switched OFF.
The DPT-EN3 has a single relay output (1-55 second Pulsed Output only) that must be connected to your Bells or Sirens.
The relay output contact can carry a load of 8 Amperes.
If the Bells or Sirens draws more current, a external contactor must be installed.
A qualified electrician must connect the timer to the existing sirens/bells.
The included Self-Latching Push Pull Connector for connecting the Timer to the Bells or Sirens must be soldered, thus the electrician must be equipped and able to do this on site.
The DPT-EN3 is shipped in a 25×16×7 cm carton and weights ± 550 gm. The package includes the DPT-EN3 Timer, Software CD-ROM, a 5.0 m USB Cable, the Self-Latching Push Pull Connector and printed Installation & Tips Sheets.
