NI TB-2706 – Front-Mount Screw-Terminal Block for NI PXI/PCI Switch and Measurement Modules

The NI TB-2706 is a front-mount, screw-terminal breakout designed to make wiring to compatible National Instruments PXI/PCI modules straightforward and dependable. From my experience, teams choose it when they want fast commissioning, clear signal labeling, and a rugged, maintenance-friendly way to bring test points out to field wiring. You might notice that it’s a passive accessory—no power, no firmware—so it typically just works, as long as you match it with the NI modules that specify TB-2706 in their accessory list.

Company’s Order Placement Process and Guarantees

• Delivery time: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Front-mount design – Attaches directly to the module front panel, reducing cable clutter and minimizing signal path length.
• Screw-terminal breakout – Quick terminations for lab and production wiring; ideal for frequent changeovers or service.
• Passive and transparent – No power or configuration required; typically supports the full electrical rating of the paired NI module.
• Numbered channel labeling – Helps techs trace signals fast during bring-up and troubleshooting.
• Robust build – Suits 24/7 ATE or validation benches where vibration and repeated maintenance are common.
• ESD-safe handling – Designed for bench and rack environments where grounded handling practices are standard.

Technical Specifications

One thing I appreciate is how it speeds up first-article wiring. A customer in automotive electronics mentioned their technicians could re-route a few dozen switch lines in under an hour, which used to take a day with custom loom cables. That kind of time saving adds up across a full rack.

Related or Supporting Products

• NI PXI/PCI switch modules that specify TB-2706 – The TB-2706 is purpose-built for the NI modules that list it as the matching terminal block. Compatibility is typically called out in each module’s accessories section.
• Label kits and wire ferrules – Helpful for dense signal maps and for keeping screw terminations consistent in high-vibration racks.
• Rack accessories (cable strain relief, tie points) – Keeps wiring neat and reduces stress on terminal screws during service.
• Alternative NI terminal blocks (model-specific) – Depending on channel density and connector style, some projects opt for other NI TB series where the module specifies a different pinout or connector.

Installation & Maintenance

• Environment: Install inside a protected enclosure or PXI rack area; maintain ambient 0–55 °C with adequate ventilation.
• Mounting: Attach the TB-2706 directly to the compatible module’s front panel using the provided captive screws. Tighten evenly to avoid connector misalignment.
• Wiring: Use quality ferrules or properly tinned leads. Keep signal and return wiring twisted where practical to minimize crosstalk.
• Grounding/ESD: Follow ESD-safe handling and bond shields to a single point to avoid ground loops.
• Torque & Recheck: After initial run-in, recheck terminal screws—vibration in racks can loosen hardware over time.
• Routine care: Periodically remove dust, verify channel labeling against your test sequence, and inspect for nicked conductors. No firmware updates required.

Quality & Certifications

• Certifications: CE and RoHS compliance are typical for NI terminal accessories.
• Manufacturer Warranty: NI products commonly include a limited warranty (model-specific). Your purchase here is covered by a 365-day warranty from us.
• Traceability: We track lot and serial information upon request to support regulated industries.
