Overview

Product overview

Key product information and technical features.

This terminal block provides accessible signal connections at the front of a compatible PXI module. It is a connection accessory, not a standalone data acquisition device.

Designed as a front-mounted connection accessory for the PXI-6115 and PXI-6120, the TB-2708 brings module I/O to accessible signal connectors. It connects directly to the module without an external interconnect cable.

Configuration switches support floating and ground-referenced analog sources. Refer to the installation guide for switch settings and signal assignments.

  • SMB connections expose AI 0–3, AO 0–1, trigger, sample-clock, and counter-output signals.
  • Analog-input configuration switches support floating and ground-referenced sources.
  • Direct mounting eliminates the cable between terminal block and DAQ module.
  • Nine SMB connectors provide accessible signal connections.
  • A 14-pin I/O connector provides digital signal access.
  • Direct attachment to supported PXI modules eliminates the module-to-terminal-block cable.
