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 Vrms, 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.
