Edge-triggered interval time-delay relay

Short description
An input pulse generates a preset number of output pulses with a defined pulse/pause ratio
(retriggerable), after a configured delay time has expired.
Symbol in IDEC
SmartRelay
Parameters TH and TL
Note the information on parameter T in topic Time response (Page 124).
The actual value of another already-programmed function can provide the pulse width TH and
the interpulse width TL. ou can use the actual values of the following functions:
Analog comparator (Page 183) (actual value Ax
Analog trigger (Page 178) (actual value Ax)
Analog amplifier (Page 191) (actual value Ax)
Analog multiplexer (Page 209) (actual value A )
Analog ramp control (Page 212) (actual value A )
Analog Math (Page 224) (actual value A )
PI controller (Page 216) (actual value A )
Up/down counter (Page 168) (actual value Cnt)
Analog filter (Page 229) (actual value A )
Average value (Page 235) (actual value A )
Max/Min (Page 231) (actual value A )
On-delay (Page 132) (current time Ta)
Off-delay (Page 136) (current time Ta)
On-/off-delay (Page 138) (current time Ta)
Retentive on-delay (Page 140) (current time Ta)
