SCXI Terminal Blocks

SCXI-1314

........................................................................................................................777687-14

Front-mounting terminal block for the SCXI-1520 module. With factory-installed and socketed

350

Ω

quarter-bridge completion resistors for each channel. Eight 120

Ω

resistors for use with

120

Ω

quarter-bridge strain gauges are included, but not installed. It also includes two factory-

installed, socketed 100 kΩ shunt calibration resistors per channel.

SCXI-1315

........................................................................................................................777687-15

8-channel front-mounting terminal block for the SCXI-1540 LVDT with six terminals for each

LVDT channel – CH+, CH-, EX+, EX-, Synch, and GND.

SCXI-1320

(see Figure 4) ................................................................................................777687-20

General-purpose terminal block for connecting signals to the SCXI-1120/D, SCXI-1121, SCXI-1125,

and SCXI-1126 modules. It includes an onboard temperature sensor for cold-junction

compensation using thermocouples, but the SCXI-1328 is recommended for precision

thermocouple measurements.

SCXI-1321

(see Figure 5) ................................................................................................777687-21

Adds nulling and shunt calibration to SCXI-1121 strain guage applications. With a front-panel

trimming potentiometer, you can manually null out the offset voltage of bridge transducers. Each

channel includes shunt calibration circuits. When activated, a switch connects a 301 kΩ shunt

resistor in parallel with the strain gauge. Both the nulling resistor and the shunt resistor are

socketed for easy customization.

SCXI-1322

........................................................................................................................777687-22

Terminal block required to connect signals to the SCXI-1122 module that includes an onboard

temperature sensor for cold-junction compensation.

SCXI-1324

........................................................................................................................777687-24

High-voltage terminal block with 48 screw terminals for the SCXI-1160 relay module.

SCXI-1325

........................................................................................................................777687-25

26-screw terminal block for the SCXI-1124 module.

SCXI-1326

........................................................................................................................777687-26

High-voltage terminal block with 48 screw terminals for the SCXI-1162 Series and SCXI-1163

Series modules.

SCXI-1327

(see Figure 6) ................................................................................................777687-27

With the SCXI-1327 you can extend the input range of the SCXI-1120/D, SCXI-1121 and

SCXI-1125 to ±300 V

rms

, and extend the threshold level of the SCXI-1126 module from 5 V up

to 300 V. The extended input voltage range is enabled or disabled on a per-channel basis using

switches located within the SCXI-1327. The SCXI-1327 also includes an onboard temperature

sensor for cold-junction compensation with thermocouples. Using the SCXI-1327 reduces the

input impedance of your SCXI module to 1 MΩ.

SCXI-1328

(see Figure 7) ................................................................................................777687-28

Isothermal terminal block with a high-precision cold-junction sensor for high-accuracy

thermocouple applications with the SCXI-1120/D, SCXI-1121, or SCXI-1125.
