SCC
SCC is a front-end signal conditioning system for M Series plug-in data
acquisition devices. An SCC system consists of a shielded carrier that holds
up to 20 single- or dual-channel SCC modules for conditioning
thermocouples and other transducers. SCC is designed for small
measurement systems where you need only a few channels of each signal
type, or for portable applications. SCC systems also offer the most
comprehensive and flexible signal connectivity options.
System features include the following.
• Modular architecture—Select your measurement technology on a
per-channel basis
• Small-channel systems—Condition up to 16 analog input and
eight digital I/O lines
• Low-profile/portable—Integrates well with other laptop computer
measurement technologies
• High bandwidth—Acquire signals at rates up to 1.25 MHz
• Connectivity—Incorporates panelette technology to offer custom
connectivity to thermocouple, BNC, LEMO
â„¢
(B Series), and
MIL-Spec connectors
Note PCI Express users should consider the power limits on certain SCC modules without
an external power supply. Refer to the specifications for your device, and the Disk Drive
Power Connector section of Chapter 3, Connector and LED Information, for information
about power limits and increasing the current the device can supply on the +5 V terminal.
Note SCC is not supported on the PCI-6221 (37-pin), USB-622x/625x Screw Terminal, or
USB-622x/625x BNC devices.
5B Series
5B is a front-end signal conditioning system for plug-in data acquisition
devices. A 5B system consists of eight or 16 single-channel modules that
plug into a backplane for conditioning thermocouples and other analog
signals. National Instruments offers a complete line of 5B modules,
carriers, backplanes, and accessories.
Note 5B is not supported on the PCI-6221 (37-pin), USB-622x/625x Screw Terminal, or
USB-622x/625x BNC devices.
