4 / 9 page SCXI Terminal Blocks 4 BUY ONLINE at ni.com or CALL 800 813 3693 (U.S.) Figure 7. SCXI-1328 Terminal Block Figure 6. SCXI-1327 Terminal Block Figure 5. SCXI-1321 Terminal Block Figure 4. SCXI-1320 Terminal Block 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 k Ω 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 k Ω 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 M Ω. 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. |
