Specifications
This appendix lists the SCB-68 specifications. These ratings are typical at
25 °C unless otherwise stated.
Analog Input
Number of channels
68-pin DAQ devices ....................... Eight differential,
16 single-ended
100-pin DAQ devices ..................... 32 differential,
64 single-ended
Temperature sensor
Accuracy ......................................... ±1.0 °C over a 0 to 110 °C range
Output ............................................. 10 mV/°C
Power Requirement
Power consumption (at +5 VDC, ±5%)
Typical ............................................ 1 mA with no signal
conditioning installed
Maximum........................................ 800 mA from host computer
Note
The power specifications pertain to the power supply of the host computer when
using internal power or to the external supply connected at the +5 V screw terminal when
using external power. The maximum power consumption of the SCB-68 is a function
of the signal conditioning components installed and any circuits constructed on the
general-purpose breadboard area. If the SCB-68 is powered from the host computer,
the m5 V current draw, which is limited by the fuse, is 800 mA.
