INSTALLATION GUIDE

SCXI -1314T TEDS Bridge Sensor 
Terminal Block

This guide describes how to install and use the SCXI-1314T terminal block 
with the SCXI-1520 module and hardware Transducer Electronic Data 
Sheet (TEDS)-enabled bridge sensors (IEEE-P1451.4 Class 2).

The SCXI-1314T terminal block works with the SCXI-1520 universal 
strain/bridge sensor module to conveniently connect hardware TEDS smart 
sensors using RJ-50 10 position/10 conductor (10p10c) modular plugs. 
There are 10 pins arranged in eight modular jacks. Each jack corresponds 
to one of the eight channels available on the SCXI-1520. For a complete 
description of the use and operation of the SCXI-1520 module, refer to the 

SCXI-1520 User Manual

.
