Overview
20 SCC modules. Conditioned analog signals are passed directly to
National Instruments SCC provides portable, modular signal the inputs of the DAQ device. SCC modules can also provide up to
conditioning to your DAQ system. SCC conditions a variety of 300 V of working isolation to voltage and current input/output
analog I/O and digital I/O signals. With this modular design, you signals from the DAQ device. Optically isolated digital I/O modules
choose your conditioning on a per-channel basis. SCC systems offer can condition digital lines from the DAQ device or you can access
custom options for various sensors or signal connection types. While them directly using the 42-pin screw terminal mounted inside the

SCC DAQ Systems
SCC Features
SCC DAQ systems consist of an SC-2345 Series shielded carrier, SCC SCC offers flexibility, customization, and ease of use in a single,
modules, a DAQ device, and a cable. Each carrier can hold up to 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
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.
