Overview

Product overview

Key product information and technical features.

The TB-2706 brings supported multifunction I/O signals to screw-terminal wiring connections. Its integrated PCB, metal enclosure, and strain relief form a front-mounted wiring assembly.

On supported multi-connector modules, the TB-2706 attaches to Connector 0 and prevents access to Connector 1. Select the terminal block against NI's model-specific accessory guide rather than connector appearance alone.

  • Screw-terminal access for supported analog, digital, and counter/timer signals.
  • Direct module attachment eliminates an external interconnect cable.
  • Metal enclosure incorporates wiring strain relief.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the TB-2706 require a separate cable?

No. It attaches directly to the front connector of a supported PXI/PXIe module.

Can Connector 1 remain in use?

No. On supported dual-connector modules, installation on Connector 0 makes Connector 1 inaccessible.

Which pinout should be used with a PXI-6143?

Use the PXI-6143 pinout in the installation guide or S Series manual, not the M Series label inside the cover.
