I'd like to use phidgets to build a data acquisition (DAQ) box. I'm a mechanical engineer, and I don't know much on electronics.
** First question, I have external analog sensors, with 0-10V output, and digital sensors, with 0/24V output. How can I interface those to the SBC? So far, I got there:
- not going with the "voltage dividers" modules as sold by phidget, as I think they are more like bridges to measure a variable resistor ;
- making up a voltage divider, but can I just plug the resistors (1kΩ ?) on the terminal blocks? Should I do something more ... clean? with a pcb etc?
For both signals I just need to divide the tension by 2, so I was thinking of plugging identical resistors between the input channel and the ground, and the input channel and the output of the sensor.
** Second question, I will have a *lot* of sensors, can I plug the usb output of a 1018 - PhidgetInterfaceKit 8/8/8 to the SBC? (I read that the SBC itself is a PhidgetInterfaceKit 8/8/8 plugged to a usb port of a mini-computer, then integrated on the same card, so I guess it's fine... isn't it?)
