Rievtech PR-6DC-DA-R - Asynchronous Pulse Generator

91
The value of ＂ＴＨ＂，＂ＴＬ＂can be set/modified in parameter mode. For information about how to
modify, refer to chapter 5.2.2 please.
Timing diagram
T
L
= 0; N = 1
Description of the function
With the change at input Trg to 1, the time T
L
(time low) is triggered. After the time T
L
has expired, output
Q is set to 1 for the duration of the time T
H
(time high).
If input Trg is retriggered prior to the expiration of the preset time (T
L
+ T
H
), the time Ta is reset and the
pulse/pause period is restarted.
If retentivity is not set, output Q and the time are reset after a power failure.
5.5.7 Asynchronous pulse generator
Fashion: Classic:
Description of function
The pulse shape at the output can be modified via a configurable pulse/pause ratio.
Connection
Description
Input En
You enable/disable the asynchronous pulse generator with
the signal at input En.
Input Inv
The Inv input can be used to invert the output signal of the
active asynchronous pulse generator..
Parameter
TL,TH: You can customize the pulse (TL)/ pause (TH)
ratio.
Retentivity set (on) = the status is retentive in memory.
Output Q
Q is toggled on and off cyclically with the pulse times T
H
and T
L
.
