Timer/pulsing relay board, + 'start' switch i/p option
Timer/pulsing relay board with optional 'start' switch or +ve pulse input,
selectable12/24v dc supply option
This is a very versatile multipurpose relay board , it can be used either as a time delay relay
* Pic microprocessor controlled.
* This timer board can be triggered either by supply voltage being applied
* or an optional normally open Start pushbutton/ switch or +ve voltage input (wired into 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.
* The board is polarised and suppressed (voltage reversal and back emf protection.)
* The relay is double pole changeover and contacts rated at 8 amp 240v ac
* Can be used for a wide range of applications -
* hobbies, camping, industrial, auto, fire & security etc.
* Input supply voltage is selected by jumper link 12 volt or 24 volt dc.
* LED illuminates to indicate relay is activated
Time delay options are selected by jumper links :-
pulse relay will pulse continuously 1 secs on, 1 secs off, when there is voltage input
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.
EXTERNAL START PUSHBUTTON SWITCH OR +VE PULSE INPUT (TO START TIME 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.
