SCXI Terminal Blocks

• Terminal blocks for quick,

easy connections

• Onboard temperature sensor

for cold-junction compensation

• Strain-relief clamps

for reliable wiring

• Isothermal construction

for high-accuracy

thermocouple measurements

• High-voltage attenuation

• AC/DC coupling

• Bridge offset nulling,

shunt calibration

• Current inputs

• Connectivity options including BNC and

thermocouple plugs

• Shielded front-mount

terminal blocks

• Rack and DIN-rail mount options

available

• Terminal block options for specific

measurement types

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.

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.

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.

SCXI-1125

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 front-

¹Accuracy 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.

²With SCXI-1102 module. With SCXI-1100 module, add error of 0.15 ˚C.

³Accuracy and repeatability include combined effects of sensor, circuitry,

and thermal gradients between the sensor and thermocouple connection.
