NI TB-4339 Terminal Block

The NI TB-4339 is a Signal Conditioning Accessory. This Terminal Block is designed to work with the PXIe-4339 Universal Bridge Input Module. The NI TB-4339 Terminal Block comes equipped with a 120 Ω quarter bridge resistor and a 50 kΩ shunt calibration resistor. The TB-4339 weighs 24.7 oz. and can be attached to the host module directly. Thus, the integrity of the signals would not be compromised because of additional cabling between the accessory and the module.

The rated trace resistance for this Terminal Block is <20 mΩ (to be measured between the screw terminal and the connector). The NI TB-4339 comes with screw terminals housed inside the plastic casing and can be accessed after removal of the upper cover. The maximum wire gauge that can be held by the screw terminals of the TB-4339 is 1.5 mm 2 (14 AWG), max. This Terminal Block does not require any calibration.
