Overview
National Instruments SCC provides portable, modular signal
conditioning to your DAQ system. SCC conditions a variety of
analog I/O and digital I/O signals. With this modular design, you
choose your conditioning on a per-channel basis. SCC systems offer
custom options for various sensors or signal connection types. While
the low-profile carrier is perfect for use with PCMCIA DAQCards
and DAQPads for portable applications, you can also use the system
for rack-mounted or desktop applications. SCC modules works with
all E Series and Basic multifunction DAQ devices.
20 SCC modules. Conditioned analog signals are passed directly to
the inputs of the DAQ device. SCC modules can also provide up to
300 V of working isolation to voltage and current input/output
signals from the DAQ device. Optically isolated digital I/O modules
can condition digital lines from the DAQ device or you can access
them directly using the 42-pin screw terminal mounted inside the
box. Relay modules add switching to your SCC DAQ system, and you
can access Analog Input, Analog Output, Digital I/O, Counter/Timer
signals as well as timing and triggering signals from the DAQ device
using feedthrough modules.
Data Acquisition and
Signal Conditioning
SCC DAQ Systems
SCC DAQ systems consist of an SC-2345 Series shielded carrier, SCC
modules, a DAQ device, and a cable. Each carrier can hold up to
SCC Features
SCC offers flexibility, customization, and ease of use in a single,
low-profile package.
Flexible I/O Options
SCC signal conditioning modules are either single or dual-channel
modules that condition analog or digital signals. SCC modules
are available for thermocouples, RTDs, strain gauges,
force/load/torque/pressure sensors, accelerometers, voltage and
current input, isolated voltage and current output frequency-to-
voltage conversion, lowpass filtering, isolated digital I/O, relay
switching and breadboarding for your custom circuitry (see Table 1
on page 252).
Module Cascading
Figure 1. SC-2345 with Configurable Connectors
SCC includes provisions for cascading two SCC analog input modules
on a single analog input channel. For example, you can pass an analog
input signal through both an attenuator module and a filter module.
