Overview
National Instruments SCXI terminal blocks provide a convenient
method for connecting and disconnecting signals to your system. The
NI SCXI-13xx front-mount terminal blocks feature direct connections
to transducers at the screw terminals located within a fully shielded
enclosure or at front-mounted BNC connectors. Strain-relief clamps hold
the signal wires safely in place. You can also choose either the TC-2095
or BNC-2095 rack-mount terminal blocks for minithermocouple
connectors or BNC connectors. These terminal blocks are ideal
solutions for high-channel-count temperature or voltage applications.
TBX DIN-rail mount terminal blocks are an alternative to the SCXI-13xx
terminal blocks which attach directly to the front of an SCXI module. The
TBX system includes shielded cables that connect the front I/O connector
of an SCXI module to a TBX terminal block.
Some terminal blocks are designed for specific input types, such as
thermocouples, strain gages, and high-voltage inputs. See tables 2, 3,
and 4 to determine which SCXI terminal blocks are compatible with your
SCXI module.

Selection Guide
Use the following steps to select the correct combination
of TBX terminal blocks and cables for your SCXI system:
1. Select the required terminal blocks – For each
SCXI module, use table 1 to select the proper TBX
terminal block. If a TBX-13xx terminal block is not
available for your SCXI module, select the appropriate
number of general-purpose TBX-24F feedthrough
terminal blocks.
2. Select cabling – For each TBX terminal block, table
1 lists the cable needed to connect the TBX terminal
block to the SCXI module. Shielded cables are available
in lengths of 1, 2, and 5 m. If using the TBX-1303, you
also have the option to build a custom cable using the
SBS-96F backshell kit. For each TBX-1303 for which you
will build a custom cable, select two SBS-96F kits.
If using the TBX-24F, you will use discrete wires to
connect the TBX-24F to an SCXI front-mounting terminal
block. Therefore, select the appropriate SCXI frontmounting terminal block for each SCXI module that
will use the TBX-24F.
3. Rack-mount accessory (optional) – If mounting
for 19 in. rack enclosures is needed, use table 2 to select
the appropriate number of TBX-RM1 rack-mount kits.

and repeatability include combined effects of sensor, circuitry,
and thermal gradients between the sensor and any screw terminal.
Thermal gradients for nonisothermal terminal blocks (SCXI-1300,
SCXI-1320, SCXI-1321, SCXI-1322, and SCXI-1327) are assumed to
be 0.4 ˚C.

3 Accuracy and repeatability include combined effects of sensor, circuitry,
and thermal gradients between the sensor and thermocouple connection.
4 Accuracy and repeatability include combined effects of sensor, circuitry,
and thermal gradients between the sensor and any screw terminal.
5 TBX-1316 is not DIN-rail mountable.
