National Instruments part number 784280-01 is an identifying part number for the TB-4300, a PXI Module Mount Terminal Block. This 96-pin female DIN to 25-pin female screw terminal adapter is designed for PXI module mounting.
The 784280-01 supports voltages up to 60 V, providing convenient and secure connections for various PXI modules. It provides an industrial PXI front-mounting Terminal Block for the PXIe-4300 PXI Analog Input Module. This Terminal Block offers screw terminal connectivity and is suitable for measurements up to 10V.
The incorporated screw terminals provide easy and fast connectivity between analog signals and the Analog Input Module. When comparing the 784280-01 with its other variants, TB-4300B and TB-4300C, notable differences can be observed in their maximum voltage and current measurement ranges. The 784280-01 offers a maximum voltage measurement range of 10 V, making it suitable for lower-voltage applications. In contrast, the TB-4300B extends this range significantly to 300 V, accommodating higher voltage measurements.
The 784280-01 also stands out with its maximum current measurement range of 20 mA, providing specialized capability for current measurements. This device supports input voltage ranges of ±1, 2, 5, and 10 V. Additionally, it provides fault voltage protection with a maximum limit of 60 V. This instrument is a hot-pluggable accessory, allowing you to connect or remove the Terminal Block without shutting down the entire measurement system. Weighing only 1 lb, the 784280-01 Terminal Block ensures convenient handling. Its mechanical alignment fins ensure proper deployment of the Terminal Block and prevent bending of the module connector pins.
