Description
No timer is universal, except this one!
2 reasons why this timer is truly universal:
1. The timer comes with a wide variety of operating modes.
2. If the built-in modes or delays don’t suit your application, you can simply tailor them according to your
needs using the supplied PC software.
Features
• 10 operating modes:
- toggle mode
- start/stop timer
- staircase timer
- trigger-at-release timer
- timer with turn on delay
- timer with turn off delay
- single shot timer
- pulse/pause timer
- pause/pulse timer
- custom sequence timer
• wide timing range
• buffered inputs for external START / STOP buttons
• heavy duty relay
• PC software for timer conguration and delay setting
Specications
• power supply: 12 VDC (100 mA max.)
• relay output: 8 A / 250 VAC max.
• minimum event time: 100 ms
• maximum event time: 1000 h (over 41 days)
• dimensions: 68 x 56 x 20 mm (2.6” x 2.2” x 0.8”)

Plugging in your board for the rst time
First, you will need to plug your VM206 into an available USB port on your computer so Windows can
detect your new device.
Then download the latest software version for the VM206 on www.velleman.eu via these simple steps:
1. go to: http://www.vellemanprojects.eu/support/downloads/?code=VM206
2. download the VM206_setup.zip le
3. unzip the les in a folder on your drive
4. double click the “setup.exe” le
An install wizard will guide you through the complete installation procedure. Shortcuts to the VM206
software can now be installed.
Starting the software
1. locate the VM206 software shortcuts
(programs > VM206 > ...).
2. click on the icon to start the main program
3. then click on the ‘Connect’ button,
the “Connected” label should now be
displayed
You are now ready to program the VM206 timer!
Timer operation modes
1: on delay - relay turns on after delay t1
2: off delay - relay turns off after delay t1
3: one shot - a single pulse of length t2, after delay t1
4: repeat cycle - after delay t1, relay turns on for t2 ; then repeats
5: repeat cycle - relay turns on for time t1, off for t2; then repeats
6: toggle mode
7: start/stop timer
8: staircase timer
9: trigger-at-release timer
10: programmable timing sequence
Now you can set up your rst timing program for the VM206:
1. select any of the options from 1 to 9
2. enter the time or use the default 2sec and 1sec
3. now click the ‘Send’ button

The VM206 is now programmed!
You can check the operation by pressing the TST1 (Start) button.
The ‘RELAY ON’ LED indicates the operation.
You can stop the timer operation by pressing the TST2 (Reset) button.

connector
To get the relay functioning as well, you need to connect the 12V supply to the SK1 screw connector.
You can disconnect the USB cable and test the timer operation as a stand-alone with the 12V supply.
On the board there are two inputs; IN1 and IN2 for remote switches or NPN transistors to control the timer
operation. The switch or transistor connected between IN1 and GND acts as the Start button (TST1) and the
switch or transistor connected between IN2 and GND acts as the Reset button (TST2).
Start - Reset
pushbuttons
Relay output
The relay contacts are connected to the SK3 connector:
• COM: Common
• NO: Normally Open
• NC: Normally Closed
g. 2
On the board, there is space provided for a transient suppressor (option) to reduce contact wear. Mount VDR1
for suppression of the NC contact. Mount VDR2 for suppression of the NO contact.

Description of the timer operation
1: On delay - relay turns on after delay t1
Timing begins on the leading edge of the Start signal.
When the set time (t1) has elapsed, the relay contacts transfer to the ON state.
The contacts remain in the ON state until the Reset signal is applied or power is interrupted.

2: Off delay - relay turns off after delay t1
When a Start signal is supplied, the relay contacts transfer immediately to the ON state.
Timing begins on the leading edge of the Start signal.
When the set time (t1) has elapsed, the relay contacts transfer to the OFF state.
The timer is reset by applying the Reset input or by interruption of power.

3: One shot - a single pulse of length t2, after delay t1
Timing begins on the leading edge of the Start signal.
When the rst set time (t1) has elapsed, the relay contacts transfer to the ON state.
The contacts remain in the ON state until the second set time (t2) has elapsed or the Reset signal is applied
or power is interrupted.

4: Repeat cycle - after delay t1, relay turns on for t2; then repeats
Timing begins on the leading edge of the Start signal.
A cycle is initiated when the output will be OFF for the rst set time (t1), then ON for the second set time (t2).
This cycle will continue until the Reset signal is applied or power is interrupted.

5: Repeat Cycle - relay turns on for time t1, off for t2; then repeats
Timing begins on the leading edge of the Start signal.
A cycle is initiated where the output will be ON for the rst set time (t1), then OFF for the second set time (t2).
This cycle will continue until the Reset signal is applied or power is interrupted.

7: Start/Stop timer
When a Start signal is supplied, the relay contacts transfer immediately to the ON state and the set time (t1) begins.
When the set time (t1) has elapsed, the relay contacts transfer to the OFF state.
The timer is reset by applying the Start signal before the set time (t1) has elapsed.

8: Staircase timer
When a Start signal is supplied, the relay contacts transfer immediately to the ON state and the set time (t1) begins.
When the set time (t1) has elapsed, the relay contacts transfer to the OFF state.
The timer is reactivated by applying the Start signal before the set time (t1) has elapsed.

9: Trigger-at-release timer
On the trailing edge of the Start signal the relay contacts transfer to the ON state and the timing begins. When
the set time (t1) has elapsed, the relay contacts transfer to the OFF state.
The timer is reactivated by applying the next trailing edge of the Start signal before the set time (t1) has
elapsed.

10: Programmable timing sequence
In this mode you can program a sequence of up to 24 timing events.
You can specify the relay state ON or OFF and the duration of each timing event. The programmed sequence
can be repeated. You can save the timing sequence to le.
