This has thrown me a curve ball so I'm looking for someone smarter than myself to provide me an answer.
I have a 24 Volt 1769-OB16 DC output card connected to 14 contactors. I am staggering when they pull in but unfortunately the inrush is 91 VoltAmps which correlates to 3.79 Amps given the system is 24 volts. The output card is rated to 2Amps for 50 milliseconds, but the inrush seems as though it could be more than the card can handle. How long does this inrush last? Anything under 10ms means the current set up will work, if not I need to either upgrade my output card or use a different network of contactors.
Respectfully,
Ryan
