About This Manual
This manual describes the electrical and mechanical aspects of the
SCXI-1120 and SCXI-1120D (SCXI-1120/D) modules and contains
information concerning their installation and operation.
The SCXI-1120 and SCXI-1120D are National Instruments Signal
Conditioning eXtensions for Instrumentation (SCXI) Series modules.
The SCXI-1120/D provides eight isolated input channels. Each channel
is independently configurable through jumpers.
The SCXI-1120 module is designed for low-cost signal conditioning of
thermocouples, volt sources, millivolt sources, and 4 to 20 mA sources
or 0 to 20 mA process-current sources where high common-mode
voltages exist.
The SCXI-1120D module is designed for low-cost signal conditioning
of volt, millivolt, and current sources that require a 20 kHz bandwidth
and where high common-mode voltages exist.
