    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 – power, ground, load and input trigger.

    The Timer can work on any DC voltage from 10 – 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 β€˜on’ or manual pushbutton
    • Special manual mode counts number of times a pushbutton is pressed
    • 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 – 40V DC
    • Fuse and reverse polarity protected
