SCXI-1326 NI High-Voltage Terminal Block

Description SCXI-1326 NI High-Voltage Terminal Block Product Dimensions： Product Description The NI SCXI‑1326 (Part Number: 777687‑26) is a shielded high‑voltage screw terminal block designed for NI’s Signal Conditioning eXtensions for Instrumentation (SCXI) platform. It serves as a rugged, front‑mount interface between SCXI signal conditioning modules (e.g., SCXI‑1162, SCXI‑1162HV, SCXI‑1163, SCXI‑1163R) and field‑wired sensors/actuators, simplifying large‑channel‑count signal connections while ensuring safety and noise immunity[6][9]. As a non‑conditioning accessory, it provides secure, isolated wiring termination to protect precision SCXI hardware and reduce electromagnetic interference (EMI)[7][22]. 2.

Weight Approx. 0.45 kg (0.99 lb) Certifications CE, UL, IEC 61010 Warranty 3 years 3. Product Advantages High‑Voltage Safety & Isolation: Rated to 300 Vrms (CAT II) with 300 Vrms bank isolation, making it ideal for high‑voltage digital I/O, temperature, and voltage applications[6][9]. Shielded Design: Integral shielding minimizes EMI, ensuring signal integrity in noisy industrial environments[6][23]. High‑Density Termination: 48 screw terminals (8 isolated banks) enable efficient large‑channel‑count connections, reducing panel space and wiring complexity[6][9]. Secure Field Wiring: Screw terminals with strain‑relief clamps provide reliable mechanical and electrical connection, reducing loose‑wire failures[22]. Module Compatibility: Directly mates with SCXI‑1162, SCXI‑1162HV, SCXI‑1163, and SCXI‑1163R modules for seamless system integration[6][9]. User‑Friendly Operation: Front‑mount design simplifies installation, wiring, and maintenance without disrupting the SCXI chassis[23]. Industrial Reliability: Wide operating temperature range and robust construction suit harsh industrial settings[4]. 4. Precautions Power‑Off Wiring: Always power down the system before connecting/disconnecting field signals to avoid electric shock or hardware damage. Voltage Compliance: Never exceed 300 Vrms per terminal; overvoltage will damage connected SCXI modules[6][9]. Isolation Adherence: Maintain bank isolation; do not cross‑wire isolated banks to prevent ground loops or short circuits[15]. Conductor Sizing: Use 0.2–2.5 mm² (24–14 AWG) conductors and tighten screws to 0.5 Nm for reliable contact. EMI Mitigation: Ensure proper grounding of the terminal block shield and strain‑relief tab (for ≥42 Vrms) to meet safety standards and reduce noise. Environmental Limits: Operate within 0–55 °C and 5–90% RH (non‑condensing); avoid corrosive atmospheres or direct moisture[4]. Module Matching: Use only with compatible SCXI modules (1162/1162HV/1163/1163R); incorrect pairing may cause measurement errors or damage[6]. Safety Grounding: For high‑voltage applications, connect the safety earth ground to the strain‑relief tab to comply with UL 1244. 5. Product Applications Industrial Automation: High‑voltage digital I/O for PLCs, machine tools, robotics, and VFD‑driven systems; large‑channel temperature/voltage monitoring in automotive, metalworking, and packaging lines[9][23]. Power & Energy: UPS systems, battery banks, renewable energy (solar/wind) inverters, and substation equipment monitoring; insulation and switch‑state monitoring in IT power systems[10]. Test & Measurement: Automated test stands for electronic components, industrial controls, and aerospace systems; multi‑channel data acquisition in R&D labs[9][23]. Building & Infrastructure: HVAC, fire safety, and emergency power systems in commercial buildings, airports, and rail facilities; large‑sensor‑array monitoring for structural integrity[10]. Marine & Offshore: Shipboard and offshore platform systems (compliant with marine safety standards); harsh‑environment sensor wiring for propulsion and process control.
