XL (LONG PULSE)
n
This will cause a momentary (.5 seconds)
closure of the contacts. This is used
for equipment that requires a longer
contact closure.
XN (LATCH ON)
This will keep the selected channels
closed until interrupted by a new
command. This permits the relays to be
used as either normally open or normally
closed. The new command can be an XS or
XL, which will cause the contact to open
momentarily and then close again.
-
XF (LATCH OFF)
Cancels the LATCH ON status and renders
the assigned channel inactive.
