This manual describes the electrical and mechanical aspects of the SCXI-1122 and contains
information concerning its operation. The SCXI-1122 is a member of the National Instruments
Signal Conditioning eXtensions for Instrumentation (SCXI) Series for the National Instruments
DAQ plug-in boards. This module is designed for signal conditioning of strain gauges, RTDs,
thermistors, thermocouples, volt and millivolt sources, and 4 to 20ÊmA sources or 0 to 20ÊmA
process-current sources where high common-mode voltages exist. The SCXI-1122 operates as 16
isolated input channels, one isolated current excitation channel, and one voltage excitation channel.
All 16 channels are isolated from earth ground but not from each other. The excitation circuits are
both isolated from earth ground, the input channels, and between each other.
