Repeat Cycle off/on DelayAirotronics Timers and Controls

Recycle Timer, Recycling Timer, Flasher. Repeat Cycle on/off Delay. Similar to Repeat Cycle Off/On Delay except that the "On" cycle is initiated first when power is applied. Application of power to the input voltage terminals starts the "On" delay cycle. At the end of the "On" delay period, the load is de-energized and the "Off" delay starts.

Sequential TimerHow To Design Your Sequence

It's connected to one of the IC2 outputs instead. I've chosen output number five. Every time the sequence runs - the clock input of IC2 is taken high - and the count advances by 1. When your chosen output pin goes high - it will "inhibit" the sequential timer. In other words - …

Positive Trigger Timer Circuit

Positive Trigger Timer circuit. When a positive pulse is applied to reset pin4, IC triggers momentarily. Since the voltage in C1 is less than 1/3 Vcc, this positive trigger turns the output high and LED turns on. The timing cycle then starts depending on the values of …

LED Sequencer | Digital Integrated Circuits | Electronics

Your circuit may produce slightly different results. Multiply the number of pulses counted at the “0” output by 10 to obtain the number of cycles produced by the 555 timer during that same time (my circuit: 79 x 10 = 790 cycles). Divide this number by 60 to obtain the number of timer cycles elapsed in each second (my circuit: 790/60 = 13.17).

This is achieved by making both J and K logic 1. The active low PR and CLR inputs take no part in the operation of this circuit so are also tied to logic 1. In toggle mode the Q output of the JK flip-flop inverts the logic levels at Q and Q at every falling edge of the clock(CK) input, also Q and Q output always remaing at opposite logic states.

NCV1455: Timer Circuit

The MC1455 monolithic timer circuit is a highly stable controller capable of producing accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In the time delay mode, time is precisely controlled by one external resistor and capacitor.

DCB51CM24Analog Timer, DCB51 Series, Asymmetrical

The DCB51CM24 is a 1 x SPDT DIN rail-mounting Combined Function Timer with asymmetrical recycler ON or OFF first selectable by connection between pins. The type DCB51 timer offers selection of time range by front knobs, knob-adjustable time setting and automatic start.

Adjustable Control Circuit for Heating Elements | Make:

 · This is the control circuit that I designed for this project. It is based around a 555 timer IC. This configuration is known as "Astable Mode." In this mode, the output of pin 3 is a series of HIGH and LOW pulses. This turns the relay off and on. The frequency and duration of these pulses is determined by the values of the resistors and the .
