NI SCXI-1313A Terminal Block – Screw‑Terminal Connectivity for NI SCXI Measurement Modules
The NI SCXI-1313A is a front‑mount terminal block for the SCXI platform, designed to bring field wiring cleanly and reliably onto your NI SCXI analog input modules. From my experience, the 1313A is the kind of hardware you install once and forget: stable connections, clear labeling, and a form factor that fits neatly on the module face without fighting for panel space. You might notice that it keeps wiring straightforward for multi-channel applications—exactly what you want in maintenance-heavy test racks or long-running monitoring setups.
Typical use cases include multi-point temperature or voltage logging on SCXI analog input modules, retrofitting legacy benches where screw-terminal access is a must, and quick sensor swaps during troubleshooting. One thing I appreciate is how it shortens the “last inch” between sensor leads and the SCXI module, which in many cases helps reduce noise pickup compared to flying leads or improvised adapters.

Key Features
- Direct front‑mount design – Attaches to the face of the compatible SCXI module, minimizing wiring distance and simplifying panel layout.
- Screw‑terminal connectivity – Tool-friendly terminals for dependable field wiring; ideal for frequent sensor changes and service work.
- Clear channel labeling – Channel marks and reference points help reduce wiring mistakes during installation or rework.
- Low‑noise routing – Short internal paths to the module input reduce the chance of pickup compared with longer fly leads.
- SCXI system fit – Works within the established SCXI chassis/module ecosystem, which is still widely used in legacy test stands.
- Passive, no external power – Nothing to configure or power; once mounted and tightened, it’s ready to use.

Quick feedback from a lab maintenance lead: “Swapping sensors on the 1313A took minutes, not hours. The channel labeling saved us a round of rewiring during commissioning.”
Installation & Maintenance
- Mounting – Power down the SCXI chassis. Align the SCXI‑1313A with the module faceplate and tighten the captive screws evenly. Avoid overtightening.
- Cabinet and ventilation – Install the SCXI chassis in a cabinet that respects airflow paths. Keep low‑level signal wiring away from high‑voltage or high‑current lines.
- Wiring practice – Use consistent wire types and lengths per channel group. Maintain good strain relief and shielding practices to minimize noise and ground loops.
- Safety – De‑energize circuits before touching field wiring. Follow sensor/vendor wiring polarity and the SCXI module’s input limits.
- Routine checks – Periodically re‑seat terminal screws, inspect for oxidation or frayed conductors, and verify channel labeling matches your system configuration.
- Firmware/Calibration – The 1313A is passive, but keep the paired SCXI module firmware/drivers current and perform regular system calibration as required by your quality plan.
