One-Shot/Retriggerable Mode

The one-shot retriggerable timer starts its timing sequence when the Initiate input changes from false to

true. See Figure 110. The timer will time for Delay Time (T1) and then the output will toggle to true for

Duration Time (T2). Additional initiate input changes of state are ignored until the timing sequence has

been completed. If a new false-to-true transition occurs on the Initiate input, the output is forced to logic

false and the timing sequence is restarted. If the T2 timer is set to 0, this timer will not function. The timer

will return to false if the Block input becomes true.

Oscillator Mode

In this mode, the Initiate input is ignored. See Figure 111. If the Block input is false, the output oscillates

with an ON time (T1) and an OFF time (T2). When the Block input is held true, the oscillator stops, and

the output is held off.

Integrating Timer Mode

An integrating timer is similar to a pickup/dropout timer except that the Pickup Time (T1) defines the rate

that the timer integrates toward timing out and setting the output to true. Conversely, the Reset Time (T2)

defines the rate that the timer integrates toward dropout and resetting the output to false. T1 defines the

time delay for the output to change to true if the initiate input becomes true and stays true. T2 defines the

Logic Timers (62)
