Velleman VM136 Interval Timer Module

I paired this timer with an Insteon I/O Linc module to make all the lights in my Insteon equipped house flash on and off while the burglar alarm sounds. I wired the timer's input (+12 V and GND) to terminals on the alarm that output 12 volts when the alarm triggers. I connected the Normally Open contacts (NO and COM) of the timer to the sensor inputs on the I/O Linc (GND and Sense). See pages 5-7 of the I/O Linc PDF manual. When the alarm triggers, the relay on the timer closes and opens and this signals the I/O Linc to turn an Insteon "scene" on and off and all the lights controlled by the devices in the scene flash.The timer as it comes from the factory, only allows the shortest "off" time to be about 2.5 seconds, too long for my application. I wanted my lights to flash on and off at about 1 second intervals. The "on" time can be set to 1 second via the "Pulse" potentiometer. However to get an "off" time of one second I had to place a 22k ohm resistor across the terminals of the "Pause" potentiometer (as pictured). Another option would be to replace the Pause pot with the same value pot as the Pulse pot (47k ohms). This would allow you to vary the off time to the same intervals as the on time.

As described

works great, easy to use

when it is assembled is called "Module". When it is not assembled is called "Kit".very good project.

Bom temporizador aleatório.

Très bon module électronique en kit pré monté. RAS

Produkt wie beschrieben, qualitativ gut und zuverlässige Funktion, Anschluss ohne Löten. Durch Verstellen der beiden Poti können alle möglichen ON/OFF-Zeiten eingestellt werden.

Es exactamente lo que queria, recibido muy bien. Funciona bien, veremos su durabilidad. De momento no hay problemas.Compraría otra vez.

très bien, facile à installer bon marché et efficace attention alimentation par 12 volts courant continu c'est indiqué mais le rappeler ne fait pas de mal
