Introduction
This chapter describes the SCXI-1102/B/C modules; lists what you
need to get started with your SCXI-1102/B/C module, the optional
software, optional equipment, and custom cables; and explains how to
unpack the SCXI-1102/B/C modules.
About the SCXI-1102/B/C Modules
♦
SCXI-1102
This module is for signal conditioning of thermocouples,
low-bandwidth volt and millivolt sources, 4 to 20 mA current sources,
and 0 to 20 mA process-current sources. The SCXI-1102 has
32 differential analog input channels and one cold-junction sensor
channel. On each channel, the SCXI-1102 has a three-pole lowpass
filter with a 2 Hz cutoff frequency to reject 60 Hz noise. Each channel
also has an amplifier with a selectable gain of 1 or 100. You can
multiplex the SCXI-1102 inputs to a single output, which drives a single
DAQ device channel.
♦
SCXI-1102B
This module is for the signal conditioning of thermocouples,
medium-bandwidth volt and millivolt sources, 4 to 20 mA current
sources, and 0 to 20 mA process-current sources. The SCXI-1102B has
32 different analog input channels and one cold-junction sensor
channel. On each channel, the SCXI-1102B has a three-pole lowpass
filter with a 200 Hz cutoff frequency. Each channel also has an
amplifier with a selectable gain of 1 or 100. You can multiplex the
SCXI-1102B inputs to a single output, which drives a single DAQ
device channel.
♦
SCXI-1102C
This module is for the signal conditioning of thermocouples,
high-bandwidth volt and millivolt sources, 4 to 20 mA current sources,
and 0 to 20 mA process-current sources. The SCXI-1102C has 32
different analog input channels and one cold-junction sensor channel.
On each channel, the SCXI-1102C has a three-pole lowpass filter with
a 10 kHz cutoff frequency. Each channel also has an amplifier with a
