Schema timer for intervals of 5 to 30 minutes incremented in 5 minute steps.

Timer function to activate an output with a time interval can be set. Done via the timing of setting the value (preset value). The timer will work if given the input and a clock pulse. For the clock pulse is supplied by the PLC manufacturer. The amount of credit value at each timer clock depends on the number of used timers. When the timer input ON timer started chopping the pulses from 0 to a preset value. When you’ve reached the preset value will activate the Outputyang been determined. timer_schema_timertimer_schema_timertimer_schema_timerThi page presents general information and some tips when using the LM555 timer. If you would like to use any of these ideas, please take time to do some testing before using them in an actual circuit. All of the solutions on this page can be applied to the LM556 Dual timer chip as well.
