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

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

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.
