Preset Electronic Timers & Counters

Preset Timer:  A control device that is inactive until started by an external command, then measures a specific time interval, after which it becomes inactive again. It times through a preset period, produces a control output, then is automatically or manually reset, awaiting another cycle to begin. A reset timer can be considered a single cycle timer. Most preset electronic timers are used to turn a load ON for a timed interval. It can be in three states: Reset, Timing and Timed-Out. When reset, the timer does not perform any timing function. The timing period starts when an external signal is received. The timed-out state is the period between the end of timing and when the timer returns to the reset state.
Preset Counter: A control device that is inactive until applied count signals accumulate until the total count matches a user entered preset limit value. It then produces a control output, then is automatically or manually reset, awaiting another cycle to begin. The control output can be used to switch/initiate machine functions for cutting, punching, starting, stopping, etc..  Some Preset Counters feature multiple preset limits.

Reset Electronic/Electric Timers

Times through a preset cycle and is then automatically or manually reset until it is restarted by an outside source. Most commonly, reset electronic/electric timers are used in industrial applications where automatic control of process time is required.

Handset timers are a form of a reset timer where the time-set knob does double duty: it sets the timing period and starts the timing interval. They are ideal when single cycle operation and low cost are required. For special applications where electric powered reset timers cannot be used, a push- button pneumatic timer can be a great problem solver. Typical pneumatic timer applications include: security systems and fire door applications.

Electronic Time Indicators / Elapsed-Timers

These electronic timersrecord and display an elapsed time but perform no output function. Various models are available with LED or LCD displays. A time indicator will time in increments or fractions of a second up to a total time of several minutes, or in increments of one hour up to a total of several years.

Repeat Cycle Electronic Timers

As the name implies, repeats the cycle of turning a load ON and OFF in a repeating pattern as long as power is applied to the unit. A repeat cycle timer can be produced in many varieties and types. All Eagle-Signal brand repeat electronic timers allow separate adjustment of the ON and OFF times. Some repeat cycle models have batch counters and allow dwell times between ON and OFF periods.
