This is a very versatile multipurpose timer relay board.
Pic microprocessor controlled.
‘Time start’ can be triggered either by :- supply voltage being applied,
an optional normally open ‘start’ pushbutton switch or a +ve voltage pulse input (wired into i/p terminal).
Suppy voltage is 12v or available in 24v dc if required.
The Relay on the board will turn on when triggered, then turn off after selected time delay.
It has a 4 way slide dil switch to select time delay.
Example of 0 - 10 second version.
Numbered 1 - 4 , to select time, slide desired switches to on position.
eg , switch 1 = 1 second,
switch 2 = 2 seconds
switch 3 = 3 seconds
switch 4 = 4 seconds
to select more than 4 seconds simply add the numbered switches together,
eg , switch 1 and 4 = 5 seconds
switch 2 and 6 = 8 seconds etc
The board time delay can be started by just applying 12vdc supply to board,
or if needed, use an optional switch or +ve signal to start time delay.
The switch if used, needs to be normally open, going closed when pressed.
This option can be used by connecting to the terminals marked i/p (REMOVE WIRE LINK)
The board is polarised and suppressed (voltage reversal and back emf protection.)
The relay is single pole changeover and with contacts capable of switching 10 amp 240vac or 10 amp 30vdc
Can be used for hobbies, fire, auto or security applications.
LED illuminates to indicate relay activation.
Board size 48 x 43 x 18mm high
Handy little timer board with dip switch time selection
available in 0-10 sec, 0-10 min, 0-100 sec, 0-100mins options
