Power Requirement 6110 and 6534

[dhruvish]

Hello,

I would like to know what's the maximum power requirement for the PCI 6110 and PCI 6543 boards. The manual says,

6110 - 5Vdc (5% tolerence), 2.5 Amp. But it then says, Power Available at I/O connector - 4.65 to 5.25 VDC at 1 Amp.

6534 - 5Vdc (5% tolerence), (with light output load)500 mAmp. and Power Available at I/O connector - 4.65 to 5.25 VDC at 1 Amp.

What is actually Maximumm Current drawn by both boards. I dont understand, what does it means by power available from I/O connector and 500 mAmp with light output load in case of 6534?

Please clarify,
Thanks
Drew

Hello,

1. For the 6110, the board requires 5V and up to 2.5A from the PC power supply. (12.5W)

The 6110 also has a +5V pin which connects internally to the +5V rail of your PC power supply. This pin is fused on the board at 1A. This means that if you are using the +5V pin to supply power externall from your board, that it could potentially draw up to 3.5A.

2. The 6534 is the same way. The light output load essentially is just an example. The 6534 has a limit on how much it can source for each line and also cumulatively. Therefore, the 6534 may require more current if the output load is heavy, but 500mA is typical.
