National Instruments SCXI-1303 Isothermal Terminal Block

USED product out of original manufacturer's box

Brand: National Instruments

Model: SCXI-1303

A terminal block, also known as a connection terminal or terminal strip, is a component used in electronics and electrical systems to facilitate the connection of wires and cables. It is commonly used in industrial applications, electrical panels, electronic equipment, and other contexts where the connection and disconnection of electrical conductors is necessary.

Terminal blocks are versatile and fundamental components in electrical systems, providing an organized and efficient way to connect and disconnect wires in a variety of applications.

The 32-channel SCXI-1303 isothermal terminal block is a shielded device

with screw terminals that connect to SCXI-1102/B/C and SCXI-1100

modules. The SCXI-1303 has a high-accuracy cold-junction thermistor

temperature sensor and an isothermal copper plane to minimize the

temperature gradients across the screw terminals when you take

measurements with thermocouples.

The terminal block has 78 screw terminals for easy signal connection.

Thirty-two pairs of screw terminals connect to the 32 differential input

of the SCXI modules. One pair of terminals connects to the chassis ground

pins of the module. Three terminals connect to the SCXI module's OUT

and AOREF pins and to the SCXIbus GUARD. All other

terminals—OUT0+, OUT0–, OUT1+, OUT1–, OUT2+, OUT2–, OUT3+,

OUT3–, and AIREF—are reserved for future use.

For each input channel, the terminal block has a pullup resistor connected

between CH+ and +5 V and a bias resistor connected between CH– and

chassis ground. These resistors help detect open thermocouples by

saturating the module amplifier output.

Applications:

Data acquisition: The SCXI-1303 can be used to acquire data from temperature, pressure, voltage, current, and other types of sensors.

Process control: The module can be used in process control systems to monitor and control process variables.

Tests and measurements: The SCXI-1303 can be used in test and measurement applications to capture and analyze sensor signals.
