Use of Arduino to control a Spike Relay

[docdavies]

Ether,

Thanks for your input. I have to admit I'm in a quandary. I've also seen info that says even the cRIO-DSC DIO output is no more than 2 mA. But I can't get anything that gives me that rock solid feeling. An Arduino can be had for $35-60 but I'm hesitant to just give it a shot.

I'm going to get a hold of a NI tech support guy I used to interface with when I was in industry. I'll put the burden of getting the info on him.

I do hope you're right since it makes the whole replacement thing much simpler.

If anyone else picks any info, I'd love to hear it!!!!!

Doc
