National Instruments 781347-01 TB-4330 PXI Terminal Block
The National Instruments 781347-01 (TB-4330) is a front-mounting terminal block designed specifically for bridge and strain gauge input modules, such as the PXIe-4330. Serving as a high-density field wiring interface, it connects an 88-pin female screw terminal front panel directly to a 96-pin female DIN ERNI back-end connector. The terminal block supports signal connectivity for voltage ranges from 0 V to 10 V, providing a secure, highly accurate termination point for quarter-, half-, and full-bridge sensor setups in automated test systems.
Engineered for precision measurement integrity, the assembly maintains exceptional signal fidelity with a trace resistance below 20 mΩ between the screw terminals and the connector for QTR EX+ and EX- excitation lines. The heavy-duty screw terminals accommodate wire gauges up to 14 AWG, facilitating stable, long-term wiring installations. Enclosed in a compact protective housing measuring 5.10 in × 6.02 in (12.95 cm × 15.29 cm) and weighing 548 g (19.3 oz), the terminal block mounts directly to the front face of compatible PXI cards without taking up additional chassis slots.
Built for rugged industrial environments, the TB-4330 operates across an ambient temperature range of 0 °C to 55 °C (tested to MIL-PRF-28800F Class 3 low-temperature and Class 2 high-temperature limits) and handles relative humidity from 5% to 95% non-condensing (verified via IEC-60068-2-56). The module is rated for Pollution Degree 2 indoor deployments at altitudes up to 2,000 meters. Mechanical durability is validated to IEC-60068-2-27 standards, withstanding operating shocks up to 30 g peak (11 ms half-sine pulse) and random vibration levels of 0.3 grms operating (2.4 grms non-operating) from 5 Hz to 500 Hz—ensuring reliable operational performance near heavy industrial machinery and structural test equipment.
