NI TB-4302C Terminal Block
Featured with a 5 Ohm built-in shunt resistor, the TB-4302C is a Terminal Block. This Terminal Block is designed for the NI PXIe-4302 and NI PXIe-4303. The NI TB-4302C enables the associated module to measure 20 mA current signals. To connect a current signal, you can use the AI terminal provided with the relevant channel on the Terminal Block.
The onboard shunt resistor covers the current signal into a voltage so it can be measured by the associated PXIe Data Acquisition Module. This Terminal Block comes with 33 terminals (labeled as VSUP) for use with an external power supply. The TB-4302C Terminal Block has 18 AISENSE terminals. This Terminal Block allows you to connect single-ended current signals, such as three-wire current transducers and loop-powered current transducers as well. This Terminal Block can be configured to operate over an input range of 0 mA to 20 mA.
