NI-9361 Block Diagram

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-effect 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 differential 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.
