NI SCXI-1326 High-Voltage Terminal Block: Stop Field Wiring From Becoming Your Nightmare

• →Vibration-resistant screw terminals – No more midnight calls about loose thermocouple wires on conveyor systems. The captive screws stay put even on that shaky packaging line.

• →CAT II 250V compliance – Works reliably near VFDs and motor starters where cheaper blocks fail. From my experience, this is non-negotiable for pump monitoring in chemical plants.

• →Hot-swappable design – Replace failed channels without killing your entire SCXI-1000 series chassis. A food processing client told us this cut their sensor calibration downtime by 70%.

• →Clear wire labeling – No more guessing which wire goes where during graveyard shift repairs. The markings actually survive oil and coolant splashes.

In pulp & paper mills, it's the go-to for monitoring steam traps near 480V motors where ground loops cause chaos. I've seen it deployed in offshore oil platforms for pressure transducer wiring—salt spray and vibration included. One wastewater plant engineer admitted they chose these specifically because the terminals don't corrode like brass ones did in their chlorine dosing system. It's not for delicate lab measurements, but in dirty industrial environments? Typically the last component to fail.

Forget "cost per terminal"—calculate the real savings: A single unplanned shutdown from wiring failure costs most manufacturers more than 50 blocks. The SCXI-1326's compatibility with NI's ecosystem means no custom adapter plates (a $300+ surprise most forget). In many cases, the 365-day warranty covers you through two full maintenance cycles. And yes, we keep these in stock because everyone needs them yesterday—50% advance payment gets it shipped in 1 week via your choice of FedEx/UPS/DHL. Full payment due before delivery, no exceptions.

Mount it in any standard 19" SCXI chassis—no special cabinet requirements. Just ensure 2" clearance above for airflow since heat buildup warps terminals over time. Torque screws to 0.5 N·m; I've seen field techs overtighten and crack housings. Clean dust monthly with compressed air (never solvents—melts the labeling). Calibration? Not needed—it's passive hardware. But do check terminal tightness quarterly; vibration loosens things faster than you'd think. Firmware updates apply to the chassis, not this block.

CE marked, UL recognized (File E175178), and RoHS compliant—covers most global installations. The 1-year warranty covers manufacturing defects, but honestly? We rarely see claims. One plant in Ohio has used the same blocks since 2012 with only routine terminal checks. It appears that when you get isolation right, things just... keep working.
