The Velleman VM188 1 Second to 60 Hour Pulse-Pause Timer (Assembled Velleman Module)

With its easy setup, wide timing range and different modes of operation, the Velleman MK188 is sure to fit a variety of applications: blinking lights, pulse a buzzer, lawn sprinklers and battery charging control just to name a few. You can set the pulse from 1 second to 60 hours and set the pause from 1 second to 60 hours. The VM188 can start with a pulse or a pause. You can also set it for a single shot (run once and stop) or a loop (run forever). The Velleman VM188 requires a 12 or 24 volt DC power supply e.g. PS1208USA. The output relay can handle a load up to 16 Amps and with its small size this kit is great for a lot of projects.

On a budget? Check out the MK188 1 Second to 60 Hour Pulse-Pause Timer (Electronic Project Kit –Soldering Required).


  • Power supply: 12-24VDC

  1. Nice product review by Marcelo on 3/15/2017

    It works as advertised. It's a bit expensive to incorporate into existing systems so I may buy kits and assemble them in house to cut costs.

Frequently Asked Questions

Q. can this be hooked to a zip cord? if i also buy PS1208USA power supply how does that hook up to the unit does it just plug in?


There are 4 grommets (one at each corner) to help you attached it.

Yes, the PS1208USA simply plugs into the VM188.
