Use of Arduino to control a Spike Relay

[docdavies]

Al,

Can you tell me then how much the relay lines from the digital side car can source? My searches have led to mentions of from 2-100 mA. And that would be from the DSC side not the cRIO.

G,

I'll look into those components....but I am but a poor biochemist, with little electronics training... Looking at those specs and little symbols gives me a tremendous head ache.....

I never thought such a simple question could be so complicated!
