NI-9361, 32-Bit, 8-Channel C Series Counter Input Module
783407-02
-
32-Bit, 8-Channel C Series Counter Input Module - The NI‑9361 is a differential or single-ended input module. With this module, you can expand beyond the four counters in CompactDAQ to reach up to 64 counters per 8‑slot chassis. 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 1 kΩ pull‑up resistor. The NI‑9361 counters can perform encoder position and velocity measurements. You can synchronize the counters with other analog, digital, and counter measurements in your chassis.
