Delay time is the time from the receipt of an output on or off command to the output actually turning on or off.
IMPORTANT
TTL outputs are inverted
(On=1=logic low voltage=0…0.4V DC;
Off=0=logic high voltage=4.5…5.5V DC).
Use a NOT instruction in the ladder program to convert to traditional
true=High logic.
