If you need to operate something for a timed period, the
eLabtronics Timer module is an easy way of doing it. Not only can
timed periods be triggered manually, they can also be turned on
automatically by changes in temperature or light levels!
The Timer is completely self-contained, with its own on-board high
output transistor. Wiring the Timer into place requires only four
connections β power, ground, load and input trigger.
The Timer can work on any DC voltage from 10 β 40V, making it safe
to use with battery or plugpack power. By adding just a few extra
components, the Timer can be automatically triggered at a certain
temperature or light level.
Adjustable time period from 1 second to 1 hour
Automatic or manual trigger
Timed outputs: one shot, delayed βonβ or manual pushbutton
Special manual mode counts number of times a pushbutton is
Can be configured to automatically trigger at certain
temperature or light level
On-board LED flashes twice per second during timed period
Can switch a maximum continuous current of 10 amps (up to 100
amps with external solid state relay)
Operates from 10 β 40V DC
Fuse and reverse polarity protected
