[Hai-users] Somfy blind control

[Larry Huppert]

Don't know how to make an OP2 directly have a contact closure for less than
1 sec, but you could have the OP2 drive a 3rd party timer relay which would
do it.  Lots of companies make timer relays which work over a wide range of
time settings from fractions of a second to hours.  The only downside is
that these relays are fairly expensive.  Take a look in the Digi-key or
Newark catalogs for these parts.
