Introduction
Product Overview:
Digital Programmable Timer
DPT–EN3 Digital Programmable Timer
The Digital Programmable Timer can be used in
all applications where a device (e.g. Siren, Bell,
Relay etc.) must be switched ON at a specific
time of day, or week. The DPT-EN3 is designed
to be connected permanently to the USB Port on
your PC, so as to ensure a consistent supply of
power.
If however, the PC is shut down, the DPT-EN3 is
battery powered and will remain operational for
approximately 7 days. The timer has a single
normally-open relay output.
The DPT-EN3 is supplied with DPT–C
ONSOLE
, a
Microsoft
®
Windows based graphical user
interface software, which allow the easy creation
of scheduled events that activates the DPT-EN3's
output relay.
All "scheduled program" data is stored in FLASH
memory, and the data cannot be lost if the unit's
power is removed. It also has the facility to
disable and enable the DPT from the PC. The
onboard clock is accurate to ± 2 minutes per
year.

accompanied product CD-ROM.
