SCXI-1300 ........................................................................................................................777687-00

The SCXI-1300 connects input signals to the SCXI-1100, SCXI-1102/B/C, and SCXI-1104/C

modules. The SCXI-1300 is a general-purpose terminal block with an onboard temperature

sensor for cold-junction compensation. Also works with SCXI-1181 and SCXI-1181K modules.

SCXI-1301 ........................................................................................................................777687-01

20-screw terminal block for the SCXI-1140, SCXI-1181, and SCXI-1181K modules.

SCXI-1302 ........................................................................................................................777687-02

50-screw terminal block for the SCXI-1180 feedthrough panel.

SCXI-1303 (see Figure 1) ................................................................................................777687-03

Terminal block for use with the SCXI-1100 and SCXI-1102/B/C modules. Designed especially for

high-accuracy thermocouple measurements, the SCXI-1303 includes isothermal construction

that minimizes errors caused by thermal gradients between terminals and the cold-junction

sensor. The SCXI-1303 also includes circuitry for open-thermocouple detection as well as

automatic ground referencing for floating (nongrounded) thermocouples.

SCXI-1304 ........................................................................................................................777687-04

The SCXI-1304, for the SCXI-114x modules, includes AC coupling circuitry, with switches on

each channel. Each channel also includes a switchable connection to ground through a 100 k

Ω

bias resistor to provide a reference for floating input sources.

SCXI-1305 (see Figure 2) ................................................................................................777687-05

Includes convenient BNC connectors for use with the SCXI-1120/D, SCXI-1121, SCXI-1125,

SCXI-1126, and SCXI-114x. Functionally equivalent to the SCXI-1304 terminal block, the

SCXI-1305 includes switchable AC coupling circuitry and ground referencing on each channel.

SCXI-1306 ........................................................................................................................779698-01

Terminal block for the SCXI-1503 RTD module. Provides 16 pairs of screw terminals for

differential input signals and 16 pairs of screw terminals for current excitation signals. You

can configure each channel for voltage or resistive measurements.

SCXI-1308 ........................................................................................................................777687-08

Current input terminal block for the SCXI-1100 and SCXI-1102/B/C analog input modules. Each

input includes a 249

Ω precision resistor so you can read 0 to 20 mA and 4 to 20 mA current

inputs.

SCXI-1310 (see Figure 3) ................................................................................................777687-10

Connector and shell assembly used to create custom cabling solutions from the SCXI-1100,

SCXI-1102/B/C, SCXI-1104/C, SCXI-114x, and SCXI-1181 to custom terminations. A low-cost

alternative to SCXI terminal blocks, it consists of a hardened plastic enclosure and one

connector with solder pins for signal connections.

SCXI-1313A ....................................................................................................................777687-13

programmatically through software commands. The SCXI-1313A also includes an onboard

temperature sensor for thermocouples cold-junction compensation.
