Overview

Product overview

Key product information and technical features.

The TB-2705 provides screw-terminal wiring at the front of a supported PXI multifunction I/O module. Its construction includes a printed circuit board, 62 screw terminals, and an enclosure with strain relief.

NI identifies the TB-2705 as a PXI-mounted accessory that attaches directly to the module front connector without an intervening cable. Select it using the accessory compatibility information for the exact DAQ module rather than assuming compatibility across all PXI devices.

The TB-2705 provides screw-terminal wiring access at the front of a supported PXI DAQ module. NI identifies it as a front-mount accessory for legacy multifunction I/O hardware, including E Series and S Series devices.

Compatibility is module-specific. NI's accessory tables distinguish supported PXI modules from PCI and PXI Express devices; a matching family name alone is not sufficient to select this terminal block.

  • Enclosure incorporates strain relief for connected wiring.
