SCC Series Modules
This chapter contains overview information on SCC modules.
Signal Conditioning Components (SCCs) are used with a shielded carrier
that connects to your 68-pin E Series device for conditioning I/O signals on
a per channel basis. Currently, SCC modules are available for voltage
attenuation, isolation, current input, strain gauge, and thermocouple input
to your E Series device. SCCs are also available for optically isolating
digital I/O signals.
SCC Shielded Carrier
The SC-2345 is a shielded carrier for SCCs that connects directly to 68-pin
E Series DAQ devices. The SC-2345 includes sockets for SCC modules,
along with a screw terminal block for convenient connection to digital and
counter/timer (GPCTR) signals of the E Series DAQ device. The SC-2345
is available with three power options.
The SC-2345 includes 20 SCC sockets, J1–J20. Sockets J1–8
accommodate SCC modules for conditioning the analog input channels of
the E Series DAQ device. Sockets J9–16 are used for dual-stage
conditioning of analog input channels. Alternatively, you can use
sockets J9–16 to access the eight digital I/O (DIO) lines of the E Series
DAQ device using either an SCC-FT01 feedthrough/breadboard module or
future digital SCC modules. DIO lines are also accessible via the screw
terminal block. Likewise, sockets J17–18 access the two analog output
channels and sockets J19–20 access the two GPCTR channels.
The SC-2345 carrier includes a 42-position screw terminal block for simple
access to digital lines of the E Series DAQ device, including DIO <0:7>,
PFI <0:9>, GPCTR, +5 V, DGND, AISENSE, FREQ_OUT,
EXTSTROBE, and SCANCLK.
The SC-2345 is available with three power options. Each SC-2345 kit
includes a power module that supplies digital power (+5 VDC) and analog
power (±15 V) to each SCC module. With the SCC-PWR01, you can power
the SC-2345 and SCC modules either with +5 VDC from the DAQ device
