NI TB-4322 Terminal Block

The National Instruments TB-4322 (Part Number: 154226-01L) is an 8-channel Terminal Block specifically designed for the PXIe-4322 Analog Output Module. This Terminal Block comes with a keying feature that prevents accidental latching with incompatible modules. The NI TB-4322 is a feedthrough Terminal Block and does not require calibration. The screw terminals incorporated in this Terminal Block are designed for 16 AWG cables. The channel-to-channel rated isolation voltage for the TB-4322 is 300 Vrms. This Terminal Block can withstand up to 1500 V surge or transient voltages as well.

The maximum voltages between any two positive and negative analog output pairs should not exceed ±120 VDC. The front of the NI TB-4322 has access to signal cables; whereas the connector is provided on the back and can easily be mated with the front connector of the PXIe-4322. Since it is a hot-swappable device, the TB-4322 Terminal Block can easily be installed or uninstalled from a live and operating measurement system.
