This manual describes the electrical and mechanical aspects of the
SCXI-1121 and contains information concerning its operation and
programming. The SCXI-1121 is a member of the National Instruments
Signal Conditioning eXtensions for Instrumentation (SCXI) Series for the
National Instruments data acquisition plug-in boards. This board is
designed for signal conditioning of strain gauges, RTDs, thermistors,
thermocouples, volt and millivolt sources, and 4 to 20 mA sources or 0 to
20 mA process-current sources where high common-mode voltages exist.
The SCXI-1121 operates as four isolated input channels and four isolated
excitation channels. Each channel is isolated and independently
configurable via jumpers.
This manual describes the installation, basic programming considerations,
and theory of operation for the SCXI-1121.
