Phidgets

[Bob Reed]

Ok folks I don't own them but I have been asked to help a guy out. Does the Phidgets 16x16 use common ground or common power? Or something different all together?

Hey Bob.  Actually Phidget Cards are completely Isolated inputs and outputs.  For instance on my LED64 Card each Led has its own + and - for the LED.  It is like the Leo Bodnar card, where you can independently connect each switch.  The outputs are also Isolated relays if I am not mistaken.  So you can run higher voltages through them.

Hope that helps.

Not really right, sorry.
0/16/16 use common ground.
That means you have the same ground for INPUT and OUTPUT,
BUT
each positive INPUT or OUTPUT can be different because it uses its own positive source (or the same if wanted).
Each OUTPUT can control up to 2A.

8/8/8 use commond ground for INPUT and OUTPUT,
but the positive for INPUT and OUTPUT is controlled by the card and not independent.
So you connect max 8 e.g. LEDs (or mini relais) direct to the common ground and each to its OUTPUT.
Same for inputs, common ground goes to all INPUT sources (switch, button, ...) and goes back to its corresponding INPUT.

LED 64 OUTPUTS are grouped (4 and 4 in 8 groups)
So all OUTPUTS are are more or less on its own, connection to LED's or e.g. mini relais to control higher load / tension.

0/0/4 Relais card, all OUTPUTS are independent and Galvanic seperated.
For high AMP load

0/0/8 Relais card, all OUTPUTS are independent and Galvanic seperated.
For low AMP load.

LOL..  Well, Going by what I have, I thought I was right, but I am glad you were able to set us both straight. Cheers Buddy. I tried
