Important note about USB-6009 input voltage limitations

[jerry w]

one more thing to be aware of.
the data sheet on this device lists the max voltage at +- 20 volts.
on the robot we have Victor controllers that pulse 12 volts to the load. a load is typically inductive. the result can by rather high voltages on the output terminals of the victor.
although the victor has suppression to avoid damage, it does not try to protect other devices on the line. it would be good practice to avoid hooking this DAQ to anything on the 12 volt side of a controller.
