NI TB-4339B Terminal Block
The TB-4339B is a variant of the TB-4339. This accessory or signal conditioning device can only be used with the PXIe-4330/4331 Universal Bridge Input Modules. The NI TB-4339B is not compatible with any other data acquisition module. This Terminal Block is designed with an integrated mechanical interlock system. Thus, it cannot be coupled with an incompatible module accidentally. The captive screws of the TB-4339B keep the module securely held with the chassis.
The NI TB-4339B is intended to be deployed on the front side of the host module. The host module must be plugged into a compatible PXI chassis. You can easily install or uninstall this module without shutting down your PXIe based acquisition system entirely. The TB-4339B comes featured with a 350-ohm quarter bridge and a 100k-ohm calibration resistor. This Terminal Block has a low trace resistance. The quality of the signal remains intact as it leaves the accessory through the main connector.
