DT9835 Key Hardware Features
The DT9835 function module provides 64 shared digital I/O lines
(grouped in banks of eight) and 32 dedicated digital input lines.
Sixteen of the 32 dedicated digital input lines are capable of
generating an interrupt to the host computer if the value of the line
changes state.
The digital outputs are capable of driving external solid-state relay
modules (sink 12 mA, source 100 kΩpullup). In addition, the board
provides isolated output common from the USB bus to 500 V peak.
