Overview

The National Instruments SC-2345 Series consists of two types of

carriers, the NI SC-2345 connector block and the SC-2345 with

configurable connectors. The SC-2350 is a similar carrier with

configurable TEDS (Transducer Electronic Data Sheet) connectors

for connecting to smart TEDS sensors. 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/time (GPCTR)

signals from the DAQ device. These carriers offer three power

options to increase the flexibility of deployment.

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 only in the

SC-2345 series carriers), 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.

Sockets J17 through J20 access the two analog output channels and

the GPCTR channels 0 and 1.
