Off-Delay Timers

Off-Delay timers operate an output when the "trigger output" is activated and continue to operate the "Off Delay" time after
the trigger has turned off.

Trigger Output: Enter the output that should trigger the activation of
the off-delay timer output.
Delay Time: Time (seconds) that the off-delay timer output should
remain on after the trigger output turns off.
Output: Output to turn on when the trigger activates and remain on
for the delay time when the trigger turns off.
Example uses include:
 Operating a heater fan so that it is synchronized with the heater's thermostat but remains on after the thermostat
has turned off to cool down the plenum and duct work.
 Operating a return tank [or similar] pump that must remain on a set time longer than a main feed pump.
 Prevent a fill valve or pump from short cycling due to a 'bouncing' float switch.
Note: The trigger and timer outputs can be set to the same output.
