Number of lines
64 shared digital I/O lines and 32 dedicated
digital input lines

a. The KUSB-3160 module can generate a PCI-bus interrupt when any of the digital
input lines corresponding to banks 10 and 11 changes state.
Termination
100 k

Pullup to +5V_I
b
b. You can drive the +5V_I isolated output pin from an external power supply. This
will allow the last digital output value to be latched to the input stage; therefore, if
the power is reduced by the host, the digital output values will not change. Current
requirements are 50 mA plus load.
