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. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
