Description
The TB-4300B is a high-quality terminal block manufactured by National Instruments, designed to be fully compatible with the PXIe-4300 PXI Analog Input Module. This terminal block falls under the SC Express category and is identified by part numbers 781338-02 and 194956-02L.
One of the key features of the TB-4300B is its ability to handle a maximum voltage of up to 300 V, thanks to its 30:1 attenuation ratio. This makes it highly suitable for applications requiring high voltage measurements. Moreover, it boasts an input impedance of 1.2 MΩ, ensuring accurate signal capture and minimal distortion.
The TB-4300B supports multiple input voltage ranges, including ±30, 60, 150, and 300 Volts, providing flexibility for various testing scenarios. Its attenuator tolerance is impressively low at 0.05 %, and it has a temperature coefficient of 5 ppm/°C, ensuring reliability and precision even under fluctuating temperature conditions.
Despite its robust capabilities, the TB-4300B remains lightweight at just 1 lb and has compact dimensions of 6.01 in. x 5.09 in., making it easy to integrate into various setups without requiring significant space. It is designed to accommodate wire gauges up to 16 AWG for screw terminals, providing versatility in connection options.
To ensure long-term reliability and performance, the TB-4300B has a recommended calibration interval of 5 years, highlighting its low maintenance needs and durability over time.
