Variable timer/pulsing relay board,+'start' i/p option
This is a very versatile multipurpose relay board , it can be used either as a variable time delay relay or as a variable pulsing relay
Has a very handy optional 'start' switch or '+ve pulse' start time delay input (wired into i/p terminals).
* This timer board can be triggered either by supply voltage being applied or an optional normally open
* "start" pushbutton/switch or '+ve pulse' input (wired into the i/p terminals).
* The relay can be set to turn on upon activation and turn off after time period or off upon activation and turn on after delay period.
* Can be used for a wide range of applications - hobbies, camping, industrial, auto, fire & security etc.
* Supply voltage is selected by jumper link 12 volt or 24 volt dc.
Variable time delay periods are adjusted by the finger adjust pots
Seconds variable 0 60 seconds
Minutes selectable 0, 1, 2, 3, 4, minutes
Total delay time with both pots set to max is 5 minutes.
Contact me if other delay time periods are required.
on>off relay will turn on with voltage input then turn off after chosen time delay.
off>on relay is off with voltage input, then turn on after chosen time delay.
Time Board will act as a normal time delay unit, variable, by using time adjust pots.
Pulse Board will pulse on and off, vary pulse rate by using time adjust pots.
EXTERNAL PUSHBUTTON SWITCH OR +VE PULSE 'START DELAY' INPUT (FOR DELAY PERIODS)
An optional input by a normally open pushbutton/ switch or +ve pulse can be used to start the board time delay periods, this is wired into the i/p terminals.
TIME ADJUST POTS MAY VARY IN COLOUR AND STYLE
IF YOU WANT THE RELAY MOUNTED IN A PLASTIC BOX ,
