NI CompactDAQ 936x series

The NI (National Instruments) CompactDAQ NI-93xx Series are a counter Input Module that features flexible, 32-bit counters. You can configure each channel to read a single pulse train or combine them to read up to four incremental encoders. You can also directly connect sensors with open-collector or push-pull outputs by using an internal, switchable pull-up resistor.

Additionally, the C Series Counter Input Module can be used to perform encoder position and velocity measurements as well as to synchronise the counters with other analog, digital, and counter measurements in your chassis
