Greetings to PCW.

Is there a config for a field output that will not cause a glitch on pull 
low if power to the i/o board combo is switched?  I have 3 circuits that 
are currently switched by sending a charge-pump to them, which I can 
still do, but I'm wondering if theres a configuration in terms 
polarity's that will not cause an ssr to be fired if its triggering led 
input, the - terminal, is direct connected, ot should I retain the use 
of the chare-pump and some home-made buckets, which give around a 200 
millisecond lag to fire after the pump signal has begun to be sent. That 
lag is immaterial in comparison to the 3 second soft startup to start 
the spindles psu. The one thats critical is the hard on ssr firing, 
which has a 3 second timer so the machine on pumps the soft start bucket 
first and triggers a oneshot to enable the fully on ssr 3 seconds after 
the machine is enabled. That can't be rushed by powerup noise as it will 
trip a 20 amp breaker in the service. Any chance of that from powerup 
glitches and I'll have to continue using the buckets.

Whats the verdict?

Thanks Peter.
