Description
Input Trg
A signal at input Trg (Trigger)
triggers the times for the
edge-triggered interval time-
delay relay.
Input R
A signal at input R resets the
current time (T
a
) and the out-
put.
Parameter
The interpulse width T
L
and
the pulse width T
H
are con-
figurable.
N determines the number of
pulse/pause cycles TL/TH:
Range of values: 1...9
Retentivity:
/ = No retentivity
R = The status is retentive.
Output Q
Q is set after TL has expired,
and reset after TH has ex-
pired.
