Data Function Description
0
No timer
1
On-delay timer
Turning the input signal on starts the on-delay timer. When the period
specified by the timer has elapsed, an output signal turns on. Turning
the input signal off turns the output signal off.
2
Off-delay timer Turning an input signal on turns an output signal on.
Turning the input signal off starts the off-delay timer. When the period
specified by the timer has elapsed, the output signal turns off.
3
Pulse (one-shot) Turning an input signal on outputs a one-shot pulse of the set timer.
4
Retriggerable timer Turning an input signal on outputs a one-shot pulse of the set timer.
However, while outputting the one-shot pulse, if the input off -> on
edge occurs again, output the one-shot pulse one more time.
5
Pulse train output
When the input turns on, the ON pulse and OFF pulse of the set timer
is repeatedly output. This function is used to flash a luminescent
device.
The operation charts for individual timers are shown below.
