SCC – Portable, Low-Cost
Signal Conditioning
• Ideal for portable measurement systems
• Wide variety of direct signal and sensor
connectivity options
• Wide range of analog and digital
conditioning options
• Measurement type selectable
on a per-channel basis
• Front-end signal conditioning
for M Series, E Series, and some
B Series multifunction DAQ devices
Configure Your SCC System in Six Steps
Step 1 – Select Your SCC Modules (Table 1)
Analog input, analog output, and digital I/O modules have dedicated
slots. You can select up to eight noncascaded modules for analog input
and eight modules for digital I/O. You can install feedthrough modules in
any slot, but they are especially useful for accessing counter/timers on
your M Series, E Series, or B Series multifunction DAQ device.
Step 2 – Choose an SCC Carrier (Table 2)
SCC carriers are available either with a hinged lid or with
configurable connectors using panelettes. Hinged lids provide quick
access to the modules. Configurable connectors provide custom signalinterface options.
Step 3 – Select Your Panelettes (Table 3)
If you have chosen an SCC carrier with configurable connectors, you can
also select connector and interface panelettes. Different carriers offer
different numbers of panelette slots. Also, some panelettes occupy more
than one slot.
Step 4 – Determine Your Power Option (Table 4)
You can power an SCC system using a +5 VDC, 120/240 VAC, or
7 to 42 VDC external power source. To indicate the power option for your
SCC system, select 01, 02, or 03 as the last two digits of the part number
of the SC-2345 or SC-2350 carrier.
Please note that if you choose power option 01, it is possible to power
your SCC system using the internal power source of your DAQ device.
For DAQCard and DAQPad devices, the total power required by your SCC
modules must be less than 800 mW (490 mW of analog power). For PCI
or PXI and M Series or E Series multifunction DAQ devices, the total
power required by your SCC modules must be less than 4.55 W (1.74 W
for analog modules). Additional power modules are sold separately. To
determine the power requirements of the modules in your SCC DAQ
system, use the online SCC Advisor at ni.com/advisors.
Step 5 – Select Your DAQ Device and Cable (Table 5)
Select the DAQ device to control your system.
Step 6 – Select Your Accessories
Choose from rack/panel-mount kits and stacking kits. You can also select
additional power kits separately if your application requires multiple
power configurations.
