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!
According to this from the first website the relay outputs from the DSC can source 7.5mA each.

To add to that in the past I have ran a spike connected directly to 2 DIO lines on a microchip part which could only source 20mA per line and it worked fine (back when i just assumed an optoisolator would not pull 65mA)

Theres seems to be something simple were missing here that hopefully someone can explain
