NI-9237

The NI‑9237 includes all the signal conditioning required to power and measure up to four bridge-based sensors simultaneously. The module provides strain or load measurements with zero interchannel phase delay. It also has 60 VDC isolation and 1,000 Vrms transient isolation, providing high‑common‑mode noise rejection and increased safety. You can program the NI‑9237 for use with half-bridge and full-bridge sensors with built-in excitation. The four RJ50 jacks provide direct connectivity to most torque or load cells and offer custom cable solutions with minimal tools.
