SCXI TBX Terminal Blocks
TBX-1303
(see Figure 11) ................................................................................................777207-03
Designed for thermocouples, with cold-junction compensation sensor, isothermal construction
with a plastic cover to minimize thermal gradients, open-thermocouple detection circuitry, and
automatic ground-referencing circuitry. With the SCXI-1102B/C, the TBX-1303 provides a high-
impedance path to ground so that systems work reliably with either floating or ground-
referenced thermocouples. For applications with the SCXI-1100, you can configure the channels
as ground-referenced or floating in blocks of eight channels. The TBX-1303 also works with the
SCXI-1181 breadboard module.
TBX-96
............................................................................................................................777264-01
Mass termination terminal block that provides a generic solution for the SCXI-1100,
SCXI-1102B/C, SCXI-1104/C, and the SCXI-1140 series.
TBX-1316
(see Figure 12) ................................................................................................777207-16
High-voltage terminal block for extending the input range of the SCXI-1120/D, SCXI-1125, or
SCXI-1126 modules to ±1000 VDC (680 V
rms
). Each input channel includes a 200:1 attenuation
circuit and offers a positive, negative, and ground terminal for up to 12 AWG wire. You can
panel mount this enclosure or simply place it on a desktop. The hinged lid makes accessing the
signals easier and key locked for safety. The TBX-1316 is rated for Category III installations.
TBX-1325
........................................................................................................................777207-25
Terminal block with 30 screw terminals for signal connections to the SCXI-1124 module. You
cable the TBX-1325 to the SCXI-1124 with the SH48-48-A shielded cable.
TBX-1326
(see Figure 13) ................................................................................................777207-26
High-voltage terminal block with 48 screw terminals for signal connections to the SCXI-1162,
SCXI-1162HV, SCXI-1163, and SCXI-1163R modules. You can cable the TBX-1326 to the SCXI
module with the SH48-48-B shielded cable. Warning: The TBX-1326 and SH48-48-B limit the
maximum working common-mode voltage between banks or between banks and earth ground
to 250 V
rms
maximum.
TBX-1328
(see Figure 14) ................................................................................................777207-28
Terminal block for the SCXI-1120/D, SCXI-1121, SCXI-1125, and SCXI-1126 modules. The
TBX-1328 includes a total of 24 screw terminals, including three terminals (CH+, CH-, and
chassis ground) for each input channel and sockets for the installation of resistors for 4 to
20 mA inputs. When used with thermocouples, the TBX-1328 maximizes measurement accuracy
with an isothermal construction and a plastic cover that minimizes thermal gradients across the
terminal block and the resulting errors.
TBX-1329
(see Figure 15) ................................................................................................777207-29
Provides selectable AC coupling for the SCXI-1120/D, SCXI-1121, SCXI-1125, and
SCXI-1126 modules.
TBX-24F
..........................................................................................................................777276-01
The TBX-24F is a general-purpose screw terminal block with feedthrough connections for
24 signal lines. You connect the TBX-24F to the SCXI module with discrete wires connected
to a standard SCXI terminal block.
