Half-Bridge Connections - National Instruments sbRIO-9218 Getting Started Manual

Half-Bridge Connections

• Connecting half bridges requires the NI-9986.
• The sbRIO-9218 provides 2 V excitation to half bridges of ≥240 Ω total or 3.3 V
excitation to half bridges of ≥700 Ω total.
• The sbRIO-9218 provides optional connections for remote sensing (RS) and shunt
calibration (SC). Remote sensing corrects for errors in excitation leads and shunt
calibration corrects for errors caused by resistance within one leg of the bridge.
