quarter-bridge setups. The SCC-SG03 works with half-bridge setups. The
SCC-SG04 works with full-bridge setups.
The SCC-SG11 is a shunt calibration module. It contains two shunt
calibration circuits you connect across your bridge setups where you want
to perform shunt calibration. The circuits are controlled by an E Series
digital output channel DIO(X).
SCC-TC01/02 Thermocouple Input Modules
The SCC-TC01 and SCC-TC02 are single-channel modules for
conditioning a variety of thermocouple types including J, K, B, E, N, R, S,
and T, and millivolt inputs with a range of ±100 mV. The SCC-TC modules
include an onboard thermistor for cold-junction compensation. The
SCC-TC01 includes a two-prong uncompensated thermocouple
miniconnector that accepts any miniature or subminiature two-prong male
thermocouple connector. The SCC-TC02 includes a removable screw
terminal plug that includes an additional connection for grounding
thermocouple shields.
SCC-FT01 Feedthrough/Breadboard Module
The SCC-FT01 is a feedthrough module that offers direct connection to
analog input or output channels of the E Series DAQ device. The
SCC-FT01 includes breadboard area for development of custom signal
conditioning circuitry for analog input, analog output, digital I/O, and
GPCTR channels of the E Series DAQ device.
SCC-LP Lowpass Filter Modules
The SCC-LP series modules are fourth-order Butterworth filter modules
that accept signals within a ±10 V range. The input signals pass through a
differential amplifier providing a differential measurement, attenuated by a
factor of two. The output of the amplifier passes through a fourth-order
Butterworth filter circuit that is buffered to allow maximum scan rates.
The SCC-LP series consist of the following modules:
The SCC-LP01—cutoff frequency, 25 Hz
The SCC-LP02—cutoff frequency, 50 Hz
The SCC-LP03—cutoff frequency, 150 Hz
