XNX-UTSI-NNNNN Honeywell Universal Transmitter – 316SS, UL/CSA, HART Output

XNX-UTSI-NNNNN – Universal Transmitter (Base Unit)

• Honeywell XNX platform – a flexible base for infrared or 4‑20 mA sensors
• Configured for Searchline Excel (IR) or Sensepoint (4‑20 mA input)
• Output: 4‑20 mA with HART® – configurable as source, sink, or isolated
• Housing: Painted 316 stainless steel – 5 x ¾″ NPT entries
• Approvals: UL / CSA / FM – suitable for North American hazardous areas
• Power: 18‑32 V DC – flexible for most industrial supplies

Manager’s Insight – Why This Base Unit?

This unit gives you a rugged stainless steel housing without a built‑in sensor. You choose the sensor type – infrared (Searchline Excel) or 4‑20 mA (Sensepoint). The 316SS enclosure resists corrosion in offshore or chemical plants. HART® lets you calibrate and diagnose from the control room. It is a smart choice for plants that need one transmitter for different sensor technologies.

Expert Review – Flexibility & Durability

The XNX‑UTSI‑NNNNN is a true universal base. It accepts IR or 4‑20 mA inputs, so you are not locked into one sensor brand. The 316SS housing handles salt spray and chemicals. The configurable output (source/sink/isolated) matches any control system. HART® simplifies maintenance. For plant engineers, this unit reduces spare parts inventory and training time. It is a future‑proof investment for multi‑sensor sites.

Frequently Asked Questions (FAQ)

• Does this unit come with a sensor?
  No. It is a base transmitter. You need to add a separate sensor (IR or 4‑20 mA).
• Can I connect a third‑party 4‑20 mA sensor?
  Yes. The input accepts generic 4‑20 mA signals from any compatible detector.
• What is the difference between source and sink mode?
  Source mode supplies current; sink mode draws current. Choose based on your PLC or DCS input type.
• Is the stainless steel housing painted?
  Yes. The paint adds extra corrosion protection – ideal for offshore use.
• What about warranty and shipping?
  12‑month warranty. We ship within 12‑24 hours via FedEx, UPS, or DHL.

Selection Guide – Which XNX Model Do You Need?

• Need a complete detector with built‑in sensor? See XNX‑AMAV‑NNCB1 (catalytic) or XNX‑UTSV‑NNIV1 (IR methane).
• Want a base unit for your own sensor? Choose this model – XNX‑UTSI‑NNNNN.
• For North America – UL/CSA/FM approved units (this model).
• For Europe / international – choose ATEX/IECEx versions.
• Need CO₂ or toxic gas detection? Select the appropriate sensor personality.
