Overview
Data Acquisition and
Signal Conditioning
The National Instruments SC-2345 Series consists of two types
of carriers, the SC-2345 connector block and the SC-2345 with
configurable connectors. These enclosures for SCC signal
conditioning modules connect directly to 68-pin DAQ devices.
They include sockets for SCC modules, along with screw terminals
for convenient connection to digital I/O and counter/timer (GPCTR)
signals from the DAQ device. These carriers offer three power
options to increase the flexibility of deployment.
Sockets J17 through J20 access the two analog output channels and
the GPCTR channels 0 and 1.

Power Module
SC-2345 Connector Block
The SC-2345 includes 20 SCC sockets, labeled J1 through J20 (see Figure
1). Sockets J1 through J8 accommodate SCC modules for conditioning
signals on the analog input channels of the DAQ device. For example, an
SCC module plugged into socket J1 conditions signals for channels 0 and
8 of the device.
You can use sockets J9 through J16 for either digital I/O modules or
dual-stage analog input conditioning. When using dual-stage
conditioning of analog inputs (for applicable modules), wire your input
signal to the first-stage module (in sockets J9 through J16).
The SC-2345 routes the output signal of the first-stage SCC module to
the input of the second stage SCC module internally (see Figure 2). When
using sockets J9 through J16 for digital I/O, simply plug in a digital SCC
module or the SCC-FT01 for custom digital applications.You can use any
combination of SCC digital input or digital output modules. The digital
I/O lines of E Series or Basic multifunction DAQ devices are configurable
for input and output on a line-by-line basis. You can also access the DIO
lines of the DAQ device using the screw terminal block.
