The NI-9361 is a channel-to-earth isolated counter input module that provides 8
flexible digital input channels that route to 8 embedded counters. The inputs are
designed for connection to encoders, hall-eect sensors, as well as many other
types of sensors with digital outputs.
You can configure the front end of each channel individually to operate in
dierential or single-ended mode.
In single-ended mode, you can configure a programmable voltage threshold level
and enable or disable an internal pull-up resistor.
