Timing relays
Pulsar T
Timing relays
Function
Use of incoming impulses to give predictable
output-impulses.
Operating functions and
applications
Figures 1 to 6 show the different timing functions
together with the applications.
fig.1 Delay On (PLT ON)
Avoid drive-way light-up in case the movement
detector "accidently" detects someone passing by.
fig.2 Delay Off (PLT OF)
The use of a delay-off timer avoids the pump
from switching on and off all the time
A hysteresis is built in.
fig.3 Delay On and Off (PLT OO)
Ventilation in toilets etc.
fig.4 Positive edge single shot (PLT PS)
Opening of automatic door. Energising the motor
during a certain time "t" in order to open the door
when movement is detected.
fig.5 Negative edge single shot (PLT NS)
Energising the motor during time "t" in order to
close the door again when no movement is
detected.
fig.6 Symmetrical flasher (PLT AS)
Flash-light.
